  • The world’s tallest 3D-printed building is in Graubünden

    The world’s tallest 3D-printed building is in Graubünden

    The Graubünden cultural foundation Nova Fundaziun Origen has realised the world’s tallest 3D-printed building together with the Swiss Federal Institute of Technology in Zurich(ETH). The new landmark of the mountain village of Mulegns at the foot of the Julier Pass is called Tor Alva, the white tower. According to an ETH report, it was inaugurated in the presence of Federal Councillor Guy Parmelin and ETH President Joël Mesot. Parmelin expressed his conviction that the building “will become a place of cultural and touristic encounter” and can stop the place from dying out.

    Tor Alva was printed in five months on the ETH Hönggerberg campus. The parts were then assembled in Savognin GR and transported to Mulegns by heavy goods vehicle along the Julierstrasse. This pioneering building, which is reminiscent of the tradition of Graubünden confectioners, demonstrates how digital construction enables load-bearing structures without formwork. Over four storeys, 32 sculptural columns of white concrete grow upwards, becoming increasingly slender and finally joining together at the very top to form a kind of open dome.

    An industrial robot applied the concrete layer by layer. A new mix was developed at ETH for this purpose, as well as the innovation of a reinforcement that grows with the building together with the ETH spin-off Mesh and Zindel United. A second robot places ring-shaped reinforcement bars in the fresh structure every 20 centimetres. In addition, vertical longitudinal reinforcement bars were inserted after printing. In addition, the researchers developed a new test procedure that allows the load-bearing capacity of 3D-printed concrete to be reliably calculated for the first time.

    Guided tours of the White Tower will be offered daily from 23 May. From July, it will also serve as a venue for theatrical performances. The tower in Mulegns will stand for around five years. After that, it can be dismantled and rebuilt elsewhere.

  • Clean energy from the summer for the winter

    Clean energy from the summer for the winter

    The growing amount of solar power in summer holds enormous potential that has so far remained untapped in the winter months. In the pilot project in Bassersdorf, surplus solar power is converted into methanol using Power-to-X and stored in the compact Hybridbox®. This innovative energy center reliably provides electricity and heat in winter, even when conventional heating systems reach their limits.

    Methanol as the key to a secure energy supply
    “Green methanol allows us to store surplus electricity locally and use it in winter with low emissions, a crucial component for a secure energy supply,” explains Boris Meier from OST. Methanol is liquid, easy to store and climate-friendly, making the Hybridbox® a flexible energy system that adapts intelligently to individual needs. Maximum efficiency is achieved by combining it with photovoltaics, battery storage and a heat pump.

    Emergency power supply and cost control
    The system is also impressive in the event of a power failure. The locally stored methanol guarantees an uninterrupted supply to the building. In addition, the high level of self-sufficiency ensures stable operating costs in the long term, a clear advantage over rising energy prices. Especially in areas without a gas or district heating connection, the system offers a real alternative to old oil or gas heating systems.

    Successful partnership for sustainable building
    The joint project shows how practical cooperation works. “The combination of energy efficiency, security of supply and CO2 reduction makes the Methanol-Hybridbox® a sustainable solution,” says Roger Balmer.

    Bringing sustainability to life
    Buildings are responsible for around a third of CO2 emissions in Switzerland. Reason enough to break new ground. The Bassersdorf project not only provides a convincing technical solution, but also makes the energy cycle tangible for visitors to the new “Sustainable Building” exhibition in the Umwelt Arena. Developers, investors and interested parties can experience how the climate-neutral living of tomorrow can be realized today. A model that can have an impact far beyond Bassersdorf.

    ProKilowatt 2025 tenders set new standards

    The submission phase for projects and programs to increase electricity efficiency in the industrial and service sectors as well as in households has been running since November 2024. With 49 applications submitted by mid-April 2025 alone, interest is around 30 percent higher than in the previous year. A record that underlines the potential for sustainable energy savings.

    Flexibility for companies – paperless and plannable
    The uncomplicated, digital application process and prompt processing within just four weeks make it easier for companies to integrate efficiency projects into their operational planning in a way that fits perfectly. Larger projects with a subsidy of up to six million francs can also be submitted at any time from this year onwards – a milestone for ambitious projects such as the replacement of large production facilities or the bundling of smaller measures.

    Concrete savings
    A project in the retail sector has already been approved for up to six million francs. Replacing existing refrigeration units will save an annual amount of electricity equivalent to the consumption of 4,500 households. Projects in industry also range from the replacement of presses and the optimization of printing machines to more efficient blowers in wastewater treatment plants.

    Competitive tenders as an instrument for the future
    The ProKilowatt program is financed by the Swiss Federal Office of Energy and implemented by CimArk SA in Sion. The subsidy, financed via a surcharge on the high-voltage grids, provides impetus for an energy-saving and competitive economy. The next deadline for project applications is November 2, 2025 – an important date for all companies that want to reduce their energy costs with innovative measures and contribute to the energy transition at the same time.

    Das Hochhaus „Rocket“ mit 100 Metern Höhe und die drei angrenzenden Wohngebäude „Tigerli“ sollen in der Lokstadt nicht nur Wohnen und Arbeiten ermöglichen, sondern auch städtebauliche Akzente setzen. Die Stadt Winterthur hat Anfang April 2025 die Baubewilligung erteilt. Allerdings mit strengen Auflagen, die vor allem die öffentliche Nutzung von Erd- und Dachgeschoss betreffen. Cham Swiss Properties AG, hervorgegangen aus der Fusion von Ina Invest und Cham Group, nimmt diese Auflagen ernst und will in enger Abstimmung mit den Behörden Optimierungen vornehmen.

    Formaler Rekurs als Zwischenschritt
    Obwohl es von externen Seiten keine Einsprachen gab, hat die Eigentümerin selbst einen Rekurs gegen die Baubewilligung eingelegt. Hintergrund ist die Notwendigkeit, die Detailvorgaben der Stadt zu präzisieren und in einem konstruktiven Dialog mit dem Amt für Städtebau und dem Amt für Baubewilligungen abzustimmen. CEO Thomas Aebischer erklärt: „Das ist eine Formalie. Entscheidend ist für uns der inhaltliche Austausch, damit Rocket & Tigerli der städtebaulichen Bedeutung vollauf gerecht werden.“

    Zentrale Punkte der Nachbesserung sind eine attraktive, öffentlich zugängliche Dachterrasse und publikumsorientierte Nutzungen im Erdgeschoss, wie Cafés und Gastronomieangebote am Dialogplatz. Diese Anpassungen sollen die Aufenthaltsqualität und die Einbindung in die Lokstadt fördern.Ein Ziel, das auch der Stadt Winterthur wichtig ist. Der Rekurs schafft die rechtliche Grundlage, um diese Punkte sorgfältig zu prüfen, ohne den laufenden Projektplan zu gefährden.

    Keine Verzögerung trotz Rekurs
    Cham Swiss Properties zeigt sich zuversichtlich, dass der Zeitplan eingehalten wird. Bereits jetzt ist klar; Rocket & Tigerli bleiben Meilensteine für den urbanen Holzbau in der Schweiz. Das Ensemble nutzt das Potenzial des zukunftsweisenden Holzhybridbaus und steht für nachhaltige Stadtentwicklung mit hoher architektonischer Qualität. Bis Ende 2028 soll das Projekt abgeschlossen sein, mit Wohnungen im Hochhaus und Hotelnutzungen in den unteren Geschossen.

    Bedeutung für Winterthur
    Für die Stadt Winterthur bedeutet das Projekt nicht nur ein neues Wahrzeichen, sondern auch zusätzliche Impulse für das Quartier Lokstadt. Als Teil einer umfassenden Transformation stärkt Rocket & Tigerli die Position der Stadt als attraktiver Wohn- und Wirtschaftsstandort und unterstreicht die Bedeutung nachhaltiger, innovativer Bauvorhaben.

  • Foundation stone laid for cutting-edge biomedical research

    Foundation stone laid for cutting-edge biomedical research

    On May 23, the University of Basel celebrated the laying of the foundation stone for the new biomedicine building on the Schällemätteli Life Science Campus together with project partners and guests from politics and science. From 2030/31, around 700 researchers will have access to a state-of-the-art infrastructure here, the University of Basel announced in a press release. “With this building, we are not only creating space for excellent research, but also promoting close spatial networking between the university, clinics and industry,” Rolf Borner, Director of Infrastructure & Operations at the University of Basel, is quoted as saying in his speech at the laying of the foundation stone.

    In the new Biomedicine building, the University intends to bring together the units of the Department of Biomedicine, which are currently spread across six different locations. It conducts research at the interface between basic science and medical application, mainly on tumor diseases, the immune system, regenerative medicine and neurosciences.

    Construction work on the building, which is over 40 meters high and has eleven floors, has been underway since 2023 and the shell is due to be completed next year. In addition to laboratories, the plans include lecture halls, seminar rooms and a lounge to promote scientific exchange. The project is being realized by the construction and real estate company Implenia from Opfikon as total contractor.

    At the groundbreaking ceremony, the University of Basel also launched the new Basel BioMed Symposium conference series. The first edition on May 23 was dedicated to the value chains of biomedical research.

  • First Zurich cantonal building to be awarded platinum

    First Zurich cantonal building to be awarded platinum

    The canton of Zurich is making history. The asylum center in Adliswil, which will be completed in 2023, is the first cantonal building to be certified with the highest SNBS Platinum award. This makes it one of only a handful of construction projects in Switzerland to have achieved this level.

    Unlike many conventional sustainability certificates, the SNBS Building Construction not only takes ecological criteria into account, but also evaluates the entire life cycle of a building and its impact on society, the environment and the economy.

    Context-strong architecture and modular efficiency
    The new building impresses with a differentiated architectural approach that incorporates both functional and social aspects. The result is a place that not only offers accommodation, but also facilitates integration. Semi-open meeting zones, planted gardens and a sports field encourage interaction and voluntary commitment.

    The modular timber construction not only guarantees high quality and cost efficiency, but also contributes to ecological goals. The short construction process, ease of dismantling and high degree of prefabrication also make the project economically attractive.

    A step beyond its own standard
    With an overall score of 5.5, the project even exceeds the cantonal targets. Zurich requires at least gold certification for new buildings, but the asylum center achieved platinum. This is confirmation of the commitment of the building construction office and the teams involved in the project.

    Signal effect for public building construction
    For investors, planners and decision-makers, the project is impressive proof that sophisticated sustainability is also feasible for public buildings and pays off in the long term. The Adliswil asylum center is therefore not only a functional building, but also a forward-looking location factor.

  • STRABAG builds utility lines in Arbon

    STRABAG builds utility lines in Arbon

    The Schlieren-based construction company STRABAG AG is building new underground pipes in Arbon, according to a press release. According to the company’s press release, the service lines in Amriswilerstrasse and Egnacherstrasse in Arbon were in a state of serious disrepair. These service lines for water, electricity, gas and the Swisscom data cables are being completely renewed. A new rainwater drain will also be created as part of the work.

    According to STRABAG, the project is characterised by the cooperation between the municipality and the utility company. The construction costs will be borne jointly.

    According to STRABAG, the last renovation of the utility lines was decades ago. Surprises were therefore inevitable during the work. For example, the employees had to uncover power lines by hand. During the process, a mistake would have led to the power being switched off in the entire neighbourhood.

    At the same time, the traffic flow and the interests of neighbours had to be kept in mind. One junction leading to an agricultural machinery park was particularly tricky because there was no way to divert traffic there. However, Ivo Schlappritzi’s team found a solution and a complete closure was avoided without delaying the construction work.

    “Thanks to careful planning and close collaboration with Innoplan Bauingenieure AG, we were able to successfully overcome the challenges on this construction site. Together as a team, we ensured that the new utility lines could be handed over to the municipality of Arbon on schedule in autumn 2025,” said Schlappritzi, STRABAG construction manager for civil engineering and road construction in the Mittelland region.

    Innoplan Bauingenieure AG is an engineering office for structural and civil engineering based in Arbon.

  • New energy centre provides climate-friendly energy

    New energy centre provides climate-friendly energy

    Regionalwerke AG Baden is tackling the expansion of district heating and cooling in Wettingen. RWB’s Terrassenbad energy centre has been successfully producing heat since April last year, the company announced in a press release. The municipality of Wettingen has also granted RWB a licence for the expansion of district heating and cooling along Seminarstrasse in Wettingen. In doing so, the municipality and company want to contribute to the goal of reducing greenhouse gas emissions in Wettingen to net zero by the end of 2025 at the latest.

    The grid construction work is set to begin this summer. Work will begin at the railway station site and Brückenstrasse. RWB plans to connect to the Terrassenbad energy centre by the end of 2026. According to the press release, the company has already acquired several well-known major customers in the area around the Terrassenbad. RWB also plans to set up a district cooling network for efficient building cooling in selected business and commercial areas.

  • Smart City Aarau Strategy 2034

    Smart City Aarau Strategy 2034

    With “Smart Aarau 2034”, the city is pursuing a forward-looking approach. The strategy does not rely on technological impetus alone, but sees digitalisation as a tool for solving complex challenges. The focus is on the needs of the population, cooperation between departments and resource-efficient implementation. Aarau is orientated towards the city’s existing development goals and integrates smart thinking into all urban projects.

    A methodological framework for real progress
    The change in strategy also means a rethink in terms of implementation. In future, projects will no longer be planned in secret, but developed in dialogue with those affected. A municipal team will provide methodical support to employees. From the initial idea to the actual tested project. Experience from the Smart City period to date shows that this approach is effective if it is applied consistently.

    Smart means networked and usable
    The new strategy puts an end to isolated islands of innovation. Instead, projects should be systemically conceived and networked across the city in future. The goal is a city that utilises its resources efficiently, can react to changes and introduces new solutions where they are actually needed. Digital tools will only be used if they contribute to quality of life or efficiency.

    Effectiveness instead of symbolic politics
    Aarau measures success not by the number of digital projects, but by their impact. The new strategic framework focuses on measurable progress. This applies to implementation, behaviour, awareness and everyday use. This makes smart thinking the new basis for urban development – comprehensible, user-centred and climate-friendly.

  • MFO-West becomes an urban neighbourhood

    MFO-West becomes an urban neighbourhood

    The purchase of the 25,500 m² ABB site by the City of Zurich for a net CHF 106 million is more than just a land purchase. It is a strategic decision with a long-term impact. Thanks to the urban development contract concluded in 2021 and the special building regulations that come into force in 2025, Zurich can shape the future on a centrally located piece of the city. With high density, mixed uses and consistent citizen participation.

    Transformation through participation
    A key success factor is the early and transparent involvement of residents, associations and neighbourhood organisations. The needs of the neighbourhood were directly incorporated into the participatory strategy process. This turned an industrial site into an urban development concept with a high level of social acceptance. Urban planning thus not only gains space, but also trust.

    Mix of uses as a driver of innovation
    The utilisation concept envisages three new construction zones and three existing areas. A mix of non-profit housing, neighbourhood supply, creative commercial use and publicly accessible open spaces is planned. The House for Culture and Circular Economy is a flagship project for innovative urban utilisation. The combination of culture, sustainability and economic activity makes the site a catalyst for new value creation models in urban areas.

    Temporary use as an impetus for location quality
    Before construction work begins, halls and open spaces are used temporarily in a targeted manner. A strategy that brings life to the neighbourhood, promotes social contacts and creates identity even before construction begins. Interim uses are increasingly recognised as a success factor for the attractiveness of locations and resilience in transformation areas.

    Public-private partnership with a role model function
    ABB remains anchored in Oerlikon with 500 jobs and supports the development. The project shows how forward-looking urban development can work constructively with private owners. A model that can be transferred to other urban conversion sites. The combination of urban management and entrepreneurial willingness to co-operate points the way forward.

    MFO-West is not an isolated case, but an exemplary model for the urban transformation of former industrial sites. Those who invest in such development areas can help shape new urban qualities. From social integration and innovative utilisation concepts to sustainable value creation. In times of housing shortages, climate targets and new forms of mobility, sites like MFO-West are the key to the city of tomorrow.

  • Innovation campus in the heart of the Engadin

    Innovation campus in the heart of the Engadin

    The Engadin is known for its cultural diversity and breathtaking nature. At the same time, the region is increasingly focussing on innovation and sustainable development. The InnHub La Punt is a place where research, entrepreneurship and education come together.

    The centre offers a wide range of uses over an area of 7,700 square metres. These include workshop and classrooms, coworking workspaces, an auditorium with 250 seats, a sports training infrastructure, a spa, a restaurant with bar and lounge, a sports shop, a tourist information centre, 44 hotel rooms and 8 tourist flats. The multifunctional premises create a dynamic environment for innovation and interdisciplinary dialogue.

    Construction begins in spring 2025
    Following a comprehensive planning phase in which the concept was further refined, construction of the InnHub La Punt will begin in spring 2025. The municipality issued the building permit in autumn 2023. The existing buildings will be demolished first, followed by the excavation and construction of the underground car park by summer 2026. The shell will be completed by mid-2027 before the interior work begins. The opening is scheduled for the end of 2028.

    In parallel with the municipality of La Punt Chamues-ch’s future projects, including the road bypass and the renaturation of the Chamuerabach stream, the InnHub will create a new centre that will revitalise the town and provide new impetus.

    Sustainability as a central building block
    A key component of the project is its sustainable approach. The building is being constructed from local wood, granite and lime mortar and is an example of the circular economy and ecologically responsible construction. “The InnHub is a matter close to my heart, as I have lived in the Engadin for years. It is an example of sustainability and innovative construction methods,” emphasised architect Norman Foster in a video message.

    The operation of the campus is also designed to be sustainable. The initiators, including Caspar Copetti, are not focussing on short-term profits, but on long-term positive effects for the region. The InnHub is intended to create new jobs, promote year-round tourism and establish an innovation ecosystem in the Engadin.

    New impetus for the economy and the community
    The InnHub La Punt will not only attract companies, start-ups and skilled workers, but also facilitate strong networking with the local population. The municipality of La Punt Chamues-ch sees the project as an important step for the further development of the region. “The campus will create a cultural and social meeting point in our village. The projects that are being created here will inspire future generations to come to La Punt,” says mayor Peter Tomaschett.

    In addition to the long-term effects for the region, the InnHub offers an InnHub PopUp even before its completion, which can be used as a co-working and event venue for locals, holiday guests and professionals until it opens.

    A milestone for the Engadin
    The InnHub La Punt combines innovation, sustainability and community in a unique way. With a clear focus on responsible development, it will radiate far beyond the Engadin and serve as a model for sustainable innovation centres in the Alpine region. The combination of state-of-the-art architecture, innovative working environments and regional roots makes the InnHub a forward-looking project that will provide new impetus for the Grisons as a business location.

  • New start-up centre promotes entrepreneurship in Uzwil

    New start-up centre promotes entrepreneurship in Uzwil

    A second startup space of the IFJ Institute for Young Entrepreneurs will be built on the site of the Uzwil grinding plant, which is located on the Bühler Group premises. Uze AG, the Bühler Group’s property and family office, is working with the IFJ to develop this part of the site on the Spickel between Bahnhofstrasse and Fabrikstrasse into an innovation hub. The IFJ has already been operating its first centre of this kind in Schlieren for ten years.

    According to Uze AG, the Mahlwerk in Uzwil will be a “lively place for start-ups, entrepreneurs and creative minds” from 2027, “with modern office & engineer spaces, events & meetings and plenty of room for innovation”. According to a statement from the IFJ, construction will begin on 12 June 2025.

    As part of the densification and renovation of properties, the Bühler Group relocated the space it used to the neighbouring main site. This freed up 18,680 square metres for something new. “Uze AG is opening a new chapter here with the Mahlwerk and continuing the industrial tradition with entrepreneurial vision, innovative strength and international networking,” says the IFJ.

    The Mahlwerk creates “space for growth, encounters and movement – and above all for visibility and strong connections to companies, experts, organisations and investors”. In addition to the space for start-ups and SMEs, there will also be premises for industrial and commercial enterprises.

  • Construction of new soil treatment plant for more sustainable concrete

    Construction of new soil treatment plant for more sustainable concrete

    STRABAG has broken ground for the construction of a wet-mechanical soil processing plant in Bürglen, according to a press release. The new plant will enable the extraction of recycled concrete from soil material and construction waste. STRABAG is also investing in a new building for its subsidiary Beton AG at the site.

    According to the company, the plant works like a “washing machine for stones”. The raw material from soils and building rubble is crushed with a crusher and then washed. In the next step, the clean stone is separated from metal, plastic, glass or wood and screened.

    The processed stones are then mixed with cement and water to produce new concrete for building houses and bridges as well as for road construction. The aim is to reduce the consumption of raw materials and promote a sustainable circular economy. “This protects the environment because we don’t have to extract as much new primary gravel from the earth. It also produces less waste,” they say.

    Installation of the plant technology is scheduled to begin in November 2025, with commissioning scheduled for autumn 2026. Production is set to begin in 2027.

  • Mirror pyramid opens up new perspectives for art and architecture

    Mirror pyramid opens up new perspectives for art and architecture

    Nüssli Schweiz AG from Hüttwilen has been commissioned by the town of Monheim am Rhein to build an extension to the Mack Pyramid, according to a press release. The pyramid was designed in 1990 by artist Heinrich Mack and architect Horst Schmidges.

    Nüssli has been awarded the construction contract as general contractor by Art Hub Immobilienverwaltungsgesellschaft der Stadt Monheim. The Thurgau event construction company will realise the architectural design H Eins by students Ruth Martin and Malte Grobenstieg, whose design won a competition organised by the Kulturkreis der deutschen Wirtschaft.

    In the new building, another mirror-inverted pyramid will be placed on top of the existing Mack building. Both the two newly created floors and the renovated old pyramid will offer spacious exhibition rooms for contemporary art. Storage and exhibition space for collections will also be created.

    The topping-out ceremony for the building is scheduled for 8 March 2026, Heinrich Mack’s 95th birthday. The first exhibitions are then scheduled to begin in autumn 2026 and full operation in June 2027.

    “We are proud that the city of Monheim am Rhein is once again relying on our extensive expertise and we are very much looking forward to successfully implementing this special project together with our partners,” said Andy Böckli, Group CEO of Nüssli, in the press release. The company has already realised the construction of an eight-court sports hall in Monheim from 2023 to 2025. This sports hall, currently the largest in Europe, was inaugurated on 31 March 2025.

  • Campus in Biel/Bienne celebrates laying of foundation stone

    Campus in Biel/Bienne celebrates laying of foundation stone

    On 6 May, the foundation stone was laid for the new Biel/Bienne campus of Bern University of Applied Sciences on the former Feldschlösschen site near Biel railway station. An education and research centre for around 2,350 students and lecturers is to be built here by 2028, the Canton of Bern ‘s Department of Construction and Transport announced in a press release. Together with the federal government and a private partner, the Canton of Bern is raising around CHF 400 million for the construction of the new campus.

    The Bern University of Applied Sciences will unite its Departments of Engineering and Information Technology as well as Architecture, Wood and Construction at the Biel/Bienne campus. According to the press release, the open architecture of the new site will promote interdisciplinary exchange and creative collaboration. The campus is designed as a cloverleaf of three building wings around a common centre.

    “An inspiring environment is being created here that focuses on openness, interdisciplinarity and high standards of infrastructure and quality,” said Cantonal Councillor Christoph Neuhaus, Director of Construction and Transport of the Canton of Bern, in the press release. “The new campus is being built as a modern timber construction – a project that stands for sustainable, climate-friendly construction.” Glenda Gonzalez Bassi, Mayor of Biel/Bienne, sees the future campus “as a central location for the development of our region, for the education of our young generation and for attracting the talent that our economy needs now more than ever.”

  • Preliminary project cantonal school Ausserschwyz in Nuolen

    Preliminary project cantonal school Ausserschwyz in Nuolen

    The demolition of the 1947 school building offers a unique opportunity to redefine the urban development of the site. A new school and village square will be created that opens up towards Seestrasse and the village. The historic Patres building will be freed from extensions and staged as a solitaire, restoring it to its original splendour.

    Modern school buildings
    The new school wing will be realised as a compact timber construction that will house classrooms and a canteen with a view of the lake. The existing gymnasium will be converted into an assembly hall and can be used flexibly as a singing hall. New music rooms and improved administrative areas will complement the available space. The buildings from 1967 and 1982 will be retained and adapted to today’s requirements with targeted interventions. A new access structure ensures a clear separation between school operations and escape routes, which enables versatile use without fire safety restrictions.

    Open space design with a historical reference
    The open space concept connects the school site with its surroundings and creates high-quality recreational areas. The newly designed square with numerous trees and a water basin is reminiscent of the site’s history as a former spa hotel. The existing sports area will be retained, supplemented by car parking spaces and equipment rooms. A metal footbridge crosses the Mühlebach canal and connects the campus with the lakeshore.

    Construction method and energy supply
    The new building fulfils the high sustainability standards and is certified according to SNBS and Minergie-A. Heating is provided by a groundwater heat pump, which also enables recooling in summer. In addition, the roof area is equipped with photovoltaic elements to generate part of the operating energy itself. Efficient mechanical ventilation ensures a pleasant indoor climate.

    An educational centre with a future
    With the renovation and partial new construction of the Ausserschwyz cantonal school in Nuolen, a future-oriented school centre is being created that combines tradition and modernity. At the same time, the new school site blends harmoniously into the townscape and will become an open, lively meeting place for the whole community.

  • Historic site becomes new cultural and educational centre

    Historic site becomes new cultural and educational centre

    The city of Schaffhausen is pursuing an ambitious goal with the redevelopment of the Kammgarn site: to transform the historic area into an attractive location for culture, education and socialising. The Schaffhausen electorate approved this project back in August 2020.
    The comprehensive redesign not only creates a better connection to the urban fabric, but also new utilisation options. In addition to the existing entrances from Baumgartenstrasse, Rheinuferstrasse and Rheinstrasse, a new passageway will be created along Klosterstrasse. This strengthens the connection with the old town and increases the attractiveness of the neighbourhood. The Kammgarn area will become part of a “string of pearls” of meeting places along the banks of the Rhine, which will enhance the area in the long term.

    More quality of stay through new open spaces
    The redesign of the Kammgarnhof will transform the inner courtyard, which was previously used as a car park, into a car-free zone. Green spaces, seating and a water feature will increase the quality of stay and turn the courtyard into a central meeting place. The redesign will enable a variety of uses for events, culture and recreation.

    Another core element of the development is the construction of a single-storey underground car park with around 90 parking spaces under the courtyard. This will make the entire area above ground car-free and open up new possibilities for use. A pergola will be erected in front of the west wing, while a spacious terrace will be created in front of the north wing.

    Modern infrastructure for culture and education
    The west wing of the Kammgarn site is being prepared for new uses as part of the refurbishment. The library and toy library will move into the ground floor and first floor. Glazed façades offer passers-by a glimpse into the world of books and games.
    The Schaffhausen University of Teacher Education will move into the second and third floors, while the fourth floor will be available for other tenants. The diverse use of the site reinforces its importance as an educational and cultural centre.

    Construction progress and archaeological work
    Construction officially began in September 2024 with the symbolic ground-breaking ceremony. Prior to this, archaeological rescue excavations were carried out, during which significant finds from the last 1000 years were discovered.

    Work is currently underway on the underground car park and the redesign of the courtyard. At the same time, the renovation of the west wing is progressing. In addition to structural measures, the façades and roof are being renovated and preparations are being made for the interior work.

    The first floor slab for the new courtyard was concreted in January 2025. To protect the valuable trees, a retaining wall (Rühlwand) is being erected around the large chestnut tree in the courtyard.

    A new meeting place for Schaffhausen
    After the remodelling, the Kammgarnhof will be an attractive place for locals and visitors to the city. Reading, meeting friends or enjoying concerts – all this will be possible in the redesigned surroundings.

    The construction of the underground car park is being financed jointly with IWC Schaffhausen, the direct neighbour of the site. This close collaboration will result in a sustainable solution that improves both the flow of traffic and the quality of life.

    A lively neighbourhood with a future
    The comprehensive renovation and redesign will transform the Kammgarn site into a modern cultural, educational and meeting centre. The connection to the old town and the Rhine will be strengthened, while new uses will enrich Schaffhausen’s cityscape. The project is scheduled for completion at the end of 2026 – a significant step for the long-term development of the city.

  • House of wood in Sursee shows the future

    House of wood in Sursee shows the future

    With six storeys made of wood, complemented by a variety of uses including offices, flats and communal areas, the Haus des Holzes impressively demonstrates the potential of modern timber construction. The entire construction, apart from the basement, is made of Swiss timber, 94 per cent of which comes from local forests. The building material grows back within just 80 minutes, a strong testament to the ecological sustainability of regional resources.

    Circular thinking consistently implemented
    The building is designed in such a way that future generations can dismantle it and reuse the building elements used. This recyclability is a key innovation driver for companies in the timber and construction industry, making sustainability tangible in practice and increasingly asserting itself as a sales argument to a climate-conscious clientele.

    Digital methods as a driver for efficiency
    A special feature of the project is the consistent use of digital planning methods. The entire building was modelled, planned and implemented using building information modelling. Tradesmen worked directly with digital models on mobile devices, an approach that raises the use of materials, construction coordination and efficiency to a new level.

    Regulatory freedom as an innovation advantage
    Switzerland offers an ideal environment for progress in timber construction with practical training, material-independent fire protection standards and flexible SIA guidelines. These framework conditions enable engineers to develop creative solutions that would be held back by rigid standards elsewhere.

    Global pioneering role in view
    The project sees itself as a driving force for the international future of timber construction. With expertise, innovative spirit and the intelligent use of digital tools, Switzerland is positioning itself as a global trendsetter. This is also evident in the largest ongoing project, the planned Dock A at Zurich Airport, where Pirmin Jung Switzerland is playing a key role in the timber-based planning.

  • Zurich Stadelhofen is open to the public

    Zurich Stadelhofen is open to the public

    With 80,000 travellers a day, Zurich Stadelhofen is a central transport hub in the city. However, the three existing tracks are overloaded and limit the growth of the S-Bahn. The construction of a fourth track and an additional tunnel in the direction of Tiefenbrunnen will massively increase capacity. An expansion that will have an impact far beyond the city limits.

    More capacity, better connections
    The expansion should enable up to 50 per cent more train movements. It paves the way for a comprehensive quarter-hourly service throughout the entire Zurich S-Bahn network. An improvement that will benefit not only the city of Zurich but also the 6 neighbouring cantons. The project involves several sections, including a new main access, improved passages and additional platform access in the Kreuzbühl-/Mühlebachstrasse area.

    Ten years of construction and an investment of CHF 1.1 billion
    The project will take around ten years to complete. If everything runs smoothly and there are no objections, construction should start in the second half of the 2020s, with commissioning scheduled for the 2030s. The estimated costs amount to around 1.1 billion Swiss francs. A significant but necessary step for a sustainable mobility infrastructure.

    Transparency and participation – project open to the public at
    The project will be open to the public in Zurich and Dübendorf from 14 May to 12 June 2025. The complete plans can be viewed in Zurich and those for the Zürichberg tunnel in Dübendorf. SBB specialists will be on hand to answer questions. A planned major expansion with room for dialogue.

  • Schwamendingen gets its Ueberlandpark

    Schwamendingen gets its Ueberlandpark

    After five and a half years of construction, the Schwamendingen enclosure was officially inaugurated. With the transfer of traffic to the extended Schöneichtunnel, the motorway noise disappears and in its place a park is created that sets new standards. The overland park is around one kilometre long, thirty metres wide and connects the neighbourhood with a green ribbon.

    More than just noise protection, a symbol of urban planning courage
    Federal Councillor Albert Rösti praised the project as a prime example of national road construction that is compatible with residential areas. The enclosure was the result of clear political will at all federal levels. Government Councillor Carmen Walker Späh also emphasised the importance of great visions for the design of vibrant, resilient cities.

    Green spaces as a climate strategy and meeting place
    For city councillor Simone Brander, the park is far more than just a design element. It counteracts the overheating of the urban climate, creates a quality of stay and strengthens social cohesion. Robust, native plants were planted, a conscious decision as the park does not require artificial irrigation.

    A park for everyone and a meeting place
    The Überlandpark was opened to the public on 10 May 2025. The neighbourhood celebrated with a pavilion, information stands and a wide range of culinary delights. The new park is open to everyone. A space for recreation, encounters and the future.

  • How Lucerne is actively designing new workspaces

    How Lucerne is actively designing new workspaces

    At the beginning of April 2025, representatives from Lucerne municipalities and regional development agencies met for the third “Location and economic development in the municipalities” forum. The event was organised by Lucerne Economic Development and the Association of Lucerne Municipalities. The forum at Lucerne University of Applied Sciences and Arts focussed on the question of how municipalities can strategically secure and develop areas for economic activities.

    Cantonal framework and digital tools
    After the opening by Ivan Buck, Director of Lucerne Economic Development, and VLG President Sibylle Boos-Braun, the Business Development team presented practice-orientated tools. These included a guide and the digital tool from start.swiss, which enables automated welcome processes for new companies in the municipality. A step towards efficient administration and location management.

    Cantonal planning as a driving force
    André Duss from the canton of Lucerne presented the planned measures for the development of workplace areas in the draft cantonal structure plan. The focus was on areas for the expansion of local companies and attractive locations for new settlements. Coordination between the canton and municipalities is to play a central role in this.

    Regional practical examples provide impetus
    Specific projects were used to illustrate how municipalities are already taking action today. LuzernPlus demonstrated successful area management with LuzernNord, flanked by developments in LuzernSüd, LuzernOst and Rothenburg-Station. The Sursee Plus pilot project, presented by Matthias Senn, also showed how densified construction in work zones can also work for land-intensive companies. Florian Furrer from Schüpfheim gave an insight into the municipal process of zoning new employment areas, an example of forward-looking planning at municipal level.

    Municipalities are actively shaping the future with
    The forum made it clear that location and business promotion starts locally. Innovative approaches, digital tools and targeted cooperation between the canton, municipalities and regions are creating new spaces for entrepreneurial development. Lucerne shows how the future is being realised.

  • Ground-breaking ceremony for large-scale solar project

    Ground-breaking ceremony for large-scale solar project

    The Baden-based energy service provider Axpo is building a solar power plant above Tujetsch, in the immediate vicinity of the Lai da Nalps reservoir. According to a press release, it will generate 11 gigawatt hours of solar power with an output of 8 megawatts per year from 2028.

    At least 10 per cent of this should be connected to the grid by the end of 2025 in order to meet the requirements of the Solar Express. Further construction stages will be completed during the summer months of the following years, and the plant should reach its full production capacity in 2028. SBB will purchase the solar power for the railway power supply over a period of 20 years. This could cover the annual electricity needs of 2,000 households.

    At the ground-breaking ceremony, the importance of the solar project for the energy transition was emphasised. “Energy production in winter is key for Switzerland – alpine solar plants like NalpSolar make an important contribution when demand is at its highest,” Antoine Millioud, Head of the Solar Division at Axpo, was quoted as saying. Axpo also expects NalpSolar to provide important insights into the technology and realisation of large-scale solar projects in challenging alpine locations.

    Martin Cavegn, Mayor of Tujetsch, emphasised the potential of the plant for a sustainable energy future and value creation in the region. The location right next to the Nalps reservoir combines existing infrastructure with new climate-friendly technology. This brings advantages for local value creation and makes Switzerland’s electricity supply more secure.

  • Modernization ensures fresh water in the spa

    Modernization ensures fresh water in the spa

    Shortly before Easter, the Wellness Hotel Stoos modernized the water technology in its Wellness & Spa. Aqua Innovation GmbH was involved as a partner, as the Rotkreuz-based company specializing in water and air treatment systems explains in a post on LinkedIn. The Aqua Innovation team put in a few extra hours to ensure that the system was back in operation in time for Easter.

    Specifically, Aqua Innovation was responsible for the installation of a high-precision programmable logic controller (PLC) and the installation of a chlorine dosing system with integrated pH control. The new control system makes it possible to monitor and control all parameters from temperature, water flow and filter cycles to chemical water treatment centrally via the building management system. “We’ll save a personal test of the system for later,” writes Aqua Innovation with a wink in the article.

  • FORUM UZH Centre for Education and Research

    FORUM UZH Centre for Education and Research

    The FORUM UZH is a milestone for the structural and academic development of the University of Zurich. The new building comprises a total of 37,000 m² of usable space and will not only accommodate the predicted growth in student numbers, but also set new standards in teaching, research and sustainability. The new centre will bring together the faculties of law, economics and modern philology. These will be complemented by modern libraries, sports facilities for secondary schools and the Academic Sports Association as well as publicly accessible cafeterias and commercial areas.

    Architecture and spatial concept
    The FORUM UZH consists of a terraced base for teaching and university life, a trapezoidal structure hovering above for research and a central courtyard. The structure is set back from Rämistrasse to create a spacious front zone with city balconies that blends in with the urban surroundings. The façade design with horizontal ceiling panels and vertical brise soleils gives the building a striking depth effect and allows for flexible light regulation inside.

    At the centre of the building is the eponymous Forum, a light-flooded hall that is a lounge, meeting and work space all in one. It connects all levels and can be used for university and public events for up to 2,000 people.

    Flexible learning environment and modern infrastructure
    The FORUM UZH offers a variety of innovative teaching and learning spaces. Five lecture theatres and several seminar rooms can be used flexibly and are equipped with state-of-the-art technology to enable hybrid teaching models. There will also be a spacious teaching and learning centre with over 700 student workstations. The university library will be united under one roof on the upper floors.

    Sustainability and innovative construction
    The FORUM UZH is based on a sustainable timber-concrete hybrid construction method that reduces CO² emissions while offering a high quality of stay. The intensively greened roof not only serves as a fifth façade, but also as an ecological compensation area with a habitat for flora and fauna. A photovoltaic system supplies its own electricity, while over 50 large trees on the redesigned town square have a positive impact on the microclimate.

    Thanks to the modular design, UZH saves as much CO² as would be released by the construction of 77 detached houses. The building will be certified in accordance with the SGNI Gold standard and Minergie P.

    Integration into the urban environment
    The FORUM UZH will not only be open to the university community, but also to the city’s population. The libraries, catering areas and neighbourhood shops will be open to the public and the Gloriaterrasse will be a green meeting place where people can linger. The urban design will create a direct link between the university quarter and the surrounding neighbourhoods.

    Construction schedule and next steps
    Following the completion of the preliminary project, construction work began in August 2024. Completion is scheduled for 2028 and the building will be occupied in 2029. Until then, students and researchers at the University of Zurich will be able to follow the development of this project of the century at close quarters.

  • Opening of the sound house at Schwendisee

    Opening of the sound house at Schwendisee

    With the Klanghaus, Toggenburg has gained a cultural landmark that radiates far beyond the region. Built from wood and embedded in the pre-Alpine landscape, the Klanghaus is not only an acoustic space, but also a platform for encounters, creativity and sound research. Four specially designed sound rooms and two outdoor stages offer space for rehearsals, concerts, workshops and sound experiments, open to professionals and amateurs alike.

    From idea to reality
    The vision of a building that makes sounds audible and tangible was sealed in 2019 with a referendum. After intensive political and social preparatory work, construction work began in 2022. With investments of 23.3 million Swiss francs, a project was realized that embodies progress in rural areas in an exemplary manner. The Klanghaus is an expression of courage and appreciation for the cultural heritage and innovative spirit of Klangwelt Toggenburg.

    More than just a building – an impulse for the region
    The Klanghaus has an impact beyond the artistic sphere. It strengthens cultural tourism, creates resonating spaces for new guests, revitalizes local businesses and inspires people to engage with sound, space and identity. As a bridge between tradition and modernity, it promotes social dialog in the heart of nature.

    Opening with a variety of sounds and encounters
    The public is invited to the grand opening weekend on May 24 and 25, 2025. The highlight is a music marathon with twelve hours of live concerts, from yodeling and gospel to youth music and indie rock. Admission is largely free and the Klanghaus will be an experience for everyone.

  • Swissgrid invests in the grid of the future

    Swissgrid invests in the grid of the future

    The transmission grid is the basis for a secure electricity supply in Switzerland and its importance is growing. Decarbonization, decentralization and digitalization are fundamentally changing the energy system. Swissgrid is responding to these developments with the “Strategic Grid 2040” project and has identified 31 key projects that need to be implemented by 2040. Around CHF 5.5 billion is to be invested in the expansion, modernization and controllability of the grid.

    Growing demands on the grid
    The transformation of the energy supply is leading to new burdens. Electricity consumption is rising sharply due to heat pumps, electromobility and data centers. At the same time, feed-in from volatile, decentralized sources is increasing. International electricity flows are increasing due to wind farms and solar farms in Europe. To meet these challenges, Swissgrid is focusing on targeted grid reinforcements, new phase-shifting transformers to control electricity flows and the comprehensive renovation of existing infrastructure.

    Planning with foresight and consideration
    The NOVA principle (grid optimization before grid reinforcement before grid expansion) is at the heart of the strategy. The grid is only expanded when all other options have been exhausted. This minimizes costs and environmental impact. At the same time, coordinated planning with cantons and partners and early involvement of the public will increase acceptance and speed up the planning process.

    Networking beyond national borders
    Swissgrid is not only planning for Switzerland, but also for the European energy future. A closer connection to the European grid and integration into a future supergrid should help to transport electricity more efficiently across continents. A regulated electricity agreement with the EU remains crucial for this integration.

  • A visionary urban development project

    A visionary urban development project

    The new urban quarter covers an area of 125,600 square meters and will provide space for around 1,700 residents and the same number of jobs. The development is based on a sustainable urban model that combines both dense construction and natural recreational zones. The project relieves pressure on the city center and at the same time creates modern, well-developed commercial areas that strengthen Solothurn’s attractiveness as a business location.

    Living space for all generations
    The new district is based on well thought-out usage concepts that are tailored to the needs of a growing urban society. A variety of housing options for singles, families and senior citizens, modern workspaces with flexible usage options as well as high-quality green and recreational spaces that contribute to the quality of life are being created. The urban location between the Aare and the old town combines the advantages of city life with the amenities of sport and recreation in the most beautiful natural surroundings. Generous public spaces and traffic-calmed zones promote a high quality of stay and support social interaction.

    Urban development with a strong neighborhood spirit
    Solothurn Weitblick is more than just a construction project, it is a model for future-oriented urban development. The mix of different forms of housing, cooperative and private residential property and a consistent focus on pedestrians promote a strong neighborhood identity. Meeting zones, green promenades and well thought-out spatial structures invite people to linger and create a lively district that encourages active participation.

    Pioneer for sustainable urban planning
    The project focuses on innovative concepts for climate adaptation. The “sponge city” principle is used to store and evaporate rainwater in order to reduce heat islands and increase resistance to heavy rainfall events. Green roofs, water systems and retention basins contribute to a pleasant microclimate and sustainably improve the district’s environmental balance.

    First construction stages successfully completed
    Development of the area has already begun. In April 2023, work began on the Brühlhof Promenade, which has been open to pedestrians and cyclists since fall 2023. Work on Oberhofstrasse and key transport links has been underway since spring 2024. The first infrastructure measures should be completed by the end of the year, creating the basis for further neighborhood development.

    A model district for the future
    The new urban quarter will create a vibrant center for modern living and working. The successful combination of city and nature and a clear vision will create a unique space for future generations. This forward-looking project sets standards for the urban development of the future and offers Solothurn the opportunity to further strengthen its identity as a liveable and innovative city.

  • District heating reaches castle on the rock

    District heating reaches castle on the rock

    BRUGG Pipes, based in Kleindöttingen, connected Vaduz Castle in Liechtenstein to a district heating network via its flexible pipe system in spring 2025. According to a press release, the logistical challenge was overcoming the steep slopes from the base station to the castle.

    When laying the 300-metre-long pipeline, a height difference of 120 meters had to be overcome to reach the castle, which is located on a rocky terrace. The installation was carried out using helicopters. The FLEXWELL-FHK pipes used were fixed to holding points previously anchored to the rock. “This innovative method made it possible to overcome the challenges of the terrain safely, quickly and efficiently,” said Daniel Schneider, Sales Manager District Heating Switzerland at BRUGG Pipes, in the press release.

    The castle grounds and the adjacent buildings will be supplied with district heating from VfA Buchs in future. The district heating will be supplied by the waste incineration plant of the Verein für Abfallentsorgung (VfA) in Buchs SG. in 2023, around 200,000 megawatt hours of district heating energy were generated and supplied here, which corresponds to the amount of energy from burning 12.5 million liters of heating oil, according to the press release.

  • Bergdietikon grants building permit for retirement and care centre

    Bergdietikon grants building permit for retirement and care centre

    The Bergdietikon municipal council has given the green light for the construction of a retirement and care centre in the Hintermatt area, according to a statement from the Oase Group. Retirement flats and care places are to be built there. The building permit is expected to come into legal force at the end of May, according to the municipality’s press release.

    Planning for the Hintermatt retirement and care centre in the Kindhausen district of Bergdietik has been ongoing for around twelve years, according to the press release. It began with a municipal assembly and the sale of the land in Hintermatt to Oase Holding AG in Baar ZG. Oase submitted the planning application in November 2023.

    The Oase Group, based in Dübendorf ZH, currently operates a wide range of residential concepts in the areas of retirement living, assisted living, care for people in need of care and long-term and palliative care at eight locations throughout Switzerland, according to the company. A further seven projects, including Bergdietikon, are in the planning stage.

    According to the guideline project on which the design plan is based, Oase will build a centre with around 64 retirement flats and 45 care places. Seven parties objected to the planning application. After the public consultation was completed in summer 2024, several objection negotiations took place between the developer and the objectors. The negotiations were concluded before Easter and the municipal council issued the building permit at its meeting on 22 April, according to a statement from the municipality.

    According to the plans of the municipality and the Oase Group, the new retirement and care home is set to open in the fourth quarter of 2027.

  • The new Lokstadt: urban, versatile, steeped in history

    The new Lokstadt: urban, versatile, steeped in history

    The “Rocket” high-rise is one of the tallest timber residential buildings in planning. With Lokstadt, Implenia is developing a new, urban and diverse district with 750 apartments for around 1500 people. Lokstadt is located south-east of Winterthur railroad station. In the past, this area was home to the workshops of the Swiss Locomotive and Machine Factory (SLM) – the most important locomotive forge in Switzerland. The neighboring Sulzer factory took over SLM in the 1960s.

    Some of the locomotives produced by SLM bear the names of the various construction fields. For example, the “Tender”: condominiums were built here, which have been occupied since mid-2023, as well as commercial space. There were also 11 “townhouses” for sale: these are four- to five-storey maisonette apartments that have already been completed. In a second construction phase, six four-storey “townhouses” were built: these comprise a total of 24 apartments and have been ready for occupancy since spring 2023. The “Elefant” office building, which is located directly on Zürcherstrasse, has also been occupied since summer 2024.

    The central Dialogplatz will be framed by three buildings in future. The first is the “Krokodil” in timber construction. Here, 254 apartments have been created to meet the diverse housing needs of three cooperatives and individual homeowners. Vertical bands of windows are reminiscent of the former industrial halls and give the building a clear structure. BIGBOY” is located at the front of Dialogplatz. The 50 meter high building with 16 floors houses 125 rental apartments as well as office and commercial space between 55 and 370 square meters. The roof terrace offers a unique view over Lokstadt and the whole of Winterthur. The industrial past of the site is reflected in the brick façade. BIGBOY was ready for occupancy in summer 2023. The third building is still under development and is currently one of the tallest planned timber residential buildings: “Rocket”, developed and realized on behalf of Ina Invest, will be 100 meters high and with 33 floors will be the landmark of the new district and the Winterthur skyline. There are plans for 272 apartments. Charitable apartments are also planned in the “Tigerli” base building. A hotel is also planned. The move-in date is planned for 2028.

    Lokstadt stands for the sustainable use of resources, a carefully planned variety of uses and the innovative revitalization of listed buildings. These include the former factory buildings. Under the leadership of Implenia, these are being transformed into spaces that reflect local history and modern city life. The district is being developed step by step in accordance with the SIA Efficiency Path 2040. Despite the dense construction, emphasis is placed on sufficient open spaces and a high quality of stay. The site will be developed with an underground car park for motorized traffic across all building plots. Above ground, pedestrians and cyclists have priority thanks to a generously designed pedestrian zone.

    With Lokstadt, Winterthur connects the 19th century with the 21st century. Here, the city’s industrial history is brought together with Winterthur’s future as a residential and service city. The district is being built for people who love city life and care about sustainability.
