  • New residential ensemble characterises Winterthur’s urban space

    New residential ensemble characterises Winterthur’s urban space

    Cham Swiss Properties is planning an urban ensemble with the construction of the Rocket high-rise and the three Tigerli residential buildings in Winterthur’s Lokstadt. Rocket & Tigerli, as the property company is calling the construction project, will offer space for 300 rental flats in future, 30 per cent of which will be in the affordable segment, according to a press release. The ensemble with the 100-metre high-rise building will therefore not only shape the Winterthur skyline, but also alleviate the city’s housing shortage.

    A building permit was already granted by the city of Winterthur in April 2025, albeit with several conditions. For example, the city demanded that the planned hotel use in the “Rocket” be abandoned in favour of the construction of rental flats. As a result of the revision, the construction company is now planning 5,000 square metres of extra living space and is dedicating the ground floor to publicly accessible retail and restaurant space instead of a hotel check-in. The top floor will also be converted with a viewing room and an area for events and catering.

    despite the challenges posed by the conversion, the architect is confident:

    “A public zone in a residential building brings challenges in terms of privacy and security. But we are confident that we will be able to implement a good solution so that the entire population can enjoy the view from a height of 100 metres,” Thomas Aebischer, CEO of Cham Swiss Properties, is quoted as saying in the press release.

    The sustainability concept of the high-rise building has also been improved: instead of a timber hybrid construction, Rocket will now be realised with CO2-equivalent alternatives that offer advantages in terms of cost-effectiveness, plannability and material availability. Certification according to the SNBS Gold standard remains planned.

    The building permit is expected to become legally binding in 2026, with construction scheduled to begin in mid-2027. Completion is expected in 2030.

  • 170-metre tower sets the tone in the Quartier de l’Étoile

    170-metre tower sets the tone in the Quartier de l’Étoile

    Halter AG, based in Schlieren, and Fordinvest (Schweiz) Immobilien GmbH, based in Pfäffikon SZ, are realising the Tour de l’Étoile 3 in Geneva. According to a press release, the high-rise building will be located in the new Quartier de l’Étoile in Geneva and will offer more than 300 flats, spaces for public facilities, restaurants, shops and services as well as a top floor open to the public. With a height of 170 metres and an area of over 50,000 square metres, it is set to become an architectural landmark in Geneva.

    The background to the project is the Praille-Acacias-Vernets(PAV) spatial planning project in Geneva. As part of this project, nine new urban neighbourhoods with over 12,000 flats, 6,000 workplaces, public facilities and open and green spaces are to be built over an area of more than 140 hectares in the coming years. The signing of the planning agreement with the Fondation Praille-Acacias-Vernets and the Canton of Geneva has now paved the way for the development of two high-rise buildings.

    Together with the high-rise building planned by Rolex, Tour de l’Étoile 3 will form a central element of the PAV development project and contribute to the social and functional diversity of the l’Étoile neighbourhood. Fordinvest acquired the existing Tour de l’Étoile back in 2000 and initiated the development of the new tower block. Halter is assuming responsibility for the realisation of Tour de l’Étoile 3 as the overall provider. The company is also already present in the PAV project with one completed high-rise project and plans to build another in 2026.

  • Planning started for new high-rise building in St.Gallen

    Planning started for new high-rise building in St.Gallen

    Schlieren-based property developer Halter AG has announced that it can begin concrete planning for a construction project with a high-rise building on Bogenstrasse in St. Gallen. The transformed site is set to offer a broad mix of residential, commercial and catering uses in the immediate vicinity of the railway station.

    The Expert Council for Urban Development and Architecture of the City of St. Gallen has approved the project draft drawn up by Halter AG in collaboration with architects Herzog & de Meuron and landscape architects Westpol for implementation in a special utilisation plan under planning law.

    According to Halter AG, there is now an indicative project ready for realisation that will serve as the basis for the upcoming parallel procedures such as the special land use plan procedure and the zoning plan amendment procedure. These are expected to take around 18 months.

    As the project progresses, the detailed design of the facades of the new high-rise building with around 80 flats will also be determined. Once the two procedures have been finalised, a planning application will be drawn up and the building permit process will begin. Construction is expected to start in 2027 if the project runs smoothly.

  • Tower complex on Sulzerallee: all of a piece

    Tower complex on Sulzerallee: all of a piece

    A tower complex is to be built on Sulzerallee in Neuhegi – in the heart of the new urban centre. The requirements for the urban setting and the architectural design of the building ensemble are correspondingly high.

    The “Gussstück” project by Graf Biscioni Architekten and Lorenz Eugster Landschaftsarchitektur was unanimously chosen as the winner of a study commission in which six architectural firms participated.

    At the intersection between Sulzerallee and the public park strip, the project envisages a 60-metre high-rise with around 145 flats and a multifunctional and flexible office building with a rental area of around 11,000 square metres, radiating out over Neuhegi.

    the planned tower complex is to be placed “precisely like a casting” at the outer end of Sulzerallee, writes the architecture firm on its website. The two buildings are to appear as an ensemble through common alignments and span an intermediate space.

    The tower complex is to be reminiscent, with various facets, of the formerly huge Giesserei site.

    At the current planning stage, the project comprises around 145 flats with a variety of different flat types, although the exact mix is still being worked out. It is important to the developer to offer a diverse range of different flat types and sizes as well as amenities. This will also allow for differentiated pricing.

    In general, the spaces are to be planned flexibly, so that a wide variety of commercial uses are also possible. The goal is to revitalise the neighbourhood with various forms of use that meet the needs of local residents and employees, but also serve as a point of attraction for external visitors.

    A photovoltaic system will be implemented with the project. It is also planned to certify both the high-rise building and the commercial building with the SNBS Gold sustainability label after completion.

    The preliminary project will be completed by May 2023, and the next step will be to work out the details of the competition project. The building application is expected to be submitted in autumn 2023, and construction is scheduled to start at the end of 2024. The client currently expects a construction period of around two years and an occupation date at the end of 2026 at the earliest.

    The site on which the tower complex is being built is being developed jointly by Mettler2-Invest and Swiss Life. The two plots are currently owned by Swiss Life. After completion of the study contract, they will be rezoned based on the winning project. Mettler2Invest will acquire the commercial part. The high-rise building with the rental flats and a small commercial part will remain in Swiss Life’s portfolio.

  • Halter plans high-rise in St.Gallen

    Halter plans high-rise in St.Gallen

    The Schlieremer construction company Halter AG is developing plans for the redevelopment of a quarter on the edge of St.Gallen’s city centre. According to a media release, a new high-rise building with high-quality architecture is planned on the Bogenstrasse site next to Kreuzbleiche. The investment costs amount to around 60 million Swiss francs.

    The planned building is to be sustainable. According to Halter, there will be below-average land consumption per capita and a minimum number of parking spaces. The building will be supplied with district heating and will also produce energy via photovoltaic systems. The new high-rise building will mainly be used for condominium and rental living. Gastronomy will be located on the ground floor. Team offices with divided areas, such as meeting rooms and co-working zones, are also planned in the new high-rise.

    “The broad utilisation concept will create a versatile place for working, living, gastronomy and culture for a mixed public,” project initiator Rolf Geiger of Halter AG is quoted as saying. The added value for the neighbourhood and the city includes the newly created public square, which will be landscaped as much as possible.

    The special use plan procedure is to be carried out in 2024 and provides for public participation. Another year is planned for the building permit procedure, followed by realisation.

    “Building inner development offers a great opportunity to make our city fit for the future. All those involved in the project want to take advantage of this opportunity with a high-quality development that combines the tried and tested with the new,” councillor Markus Buschor of the Planning and Construction Directorate is quoted as saying.

  • Centurion Tower: Tight as an officer

    Centurion Tower: Tight as an officer

    With its clear volume, the new high-rise integrates itself as a matter of course into the urban structure of the new “Vision Mitte” quarter. It takes up the lines of the surrounding buildings and forms, so to speak, the last piece of the puzzle in the large cluster of buildings of the university of applied sciences and office and industrial buildings on this site. The building was not named after the number of flats, of course, but after the famous Roman excavation site in Windisch (Vindonissa).

    The right type of wall for every use
    The 16 condominiums are located on the top four floors of the tower, the 116 rental flats on the 3rd to 10th floors. On the lowest three floors, the Centurion Towerhotel with 66 flats and rooms meets the needs of many regional businesses as well as the neighbouring technical college. These different uses are reflected not least in the materialisation and design within the building. The tower was raised as a skeleton structure and completely finished with non-load-bearing gypsum drywall systems.

    The (almost) all-rounder
    Hydrophobised Rigips® Habito board plays a central role in the kitchens and wet rooms of the condominiums. It is probably one of the most versatile gypsum boards available and is suitable for residential, office and commercial construction, but also for hotels, hospitals and schools. During development, the focus was on an optimal room climate and easy processing. The revolutionary product was uncompromisingly optimised for these properties and equipped with the best performance data and a wide range of applications. The board is very robust, fire-resistant, sound-insulating, ecologically sustainable and efficient to work with.

    A lot of planning and conversion freedom
    As soon as a brick wall is replaced with the Rigips® Habito system, the advantages multiply. There is no need to measure and install load-reinforcing wall inserts, because force loads such as furniture, pictures or TV screens can be screwed on directly without dowels. For the same reason, there is no need to determine the wall inserts at an early stage, which increases planning freedom. Habito is therefore as stable as a Roman legionnaire or as a conventional solid wall. With all these strengths in terms of building physics and con-
    struction, thanks to planning with gypsum drywall systems, there remains sufficient flexibility for later conversions if the utilisation requirements of individual rooms or even floors should change.

    Gypsum drywall construction has also long been able to keep up at this level.

  • Green light for the Unterfeld project in Baar

    Green light for the Unterfeld project in Baar

    The subfield is one of the last large contiguous building land reserves and has been declared a cantonal agglomeration area. The location directly on the municipal boundary between Baar and Zug is adjacent to the Lorze recreation zone and offers a lot of development potential. But sometimes such comprehensive concepts need more than one try. This is also the case with the Unterfeld area planning: After the population of Baar had spoken out against cross-border planning in spring 2017, the “Unterfeld Süd” project was waved through in September 2020 in the second attempt by the voters with 65 percent yes-votes.

    The project was redeveloped under the leadership of the Baar municipality and in a team of 50. The team consisted of experts from the fields of urban development and landscape architecture, representatives of the authorities and landowners as well as residents, supporters and opponents of the earlier project, members of specialist committees and associations as well as local parties.

    Building on the district design plan, the zoning plan and the building regulations have been coordinated. An agreement has been reached on the construction of a sustainable quarter that enables new ways of living, living and working. Four building sites are being built over in stages. Rental apartments and condominiums are planned. The creation of office and service areas as well as public-oriented uses on some of the ground floors are also planned. A neighborhood square, a spacious boulevard for non-motorized traffic and a lot of green space ensure sufficient open space. Three high-rise buildings with heights of 60, 50 and 40 meters are to be built.

    The architecture competition for the first construction phase has already started. The Baar municipal assembly is expected to decide on the development plan in 2022. The first groundbreaking is unlikely to take place before summer 2023. First of all, the 60-meter high-rise near the Lindenpark S-Bahn station and the neighboring office building are to be built. The other construction areas are being developed further in parallel.

    The owners are Implenia Immobilien AG, Ina Invest AG and the Stocker heirs. Implenia is responsible for the site development. The company is developing plots 1A and 4 as the owner and plots 1B and 3 on behalf of Ina Invest. The two local housing cooperatives, the Baar family and the Liberale Baar cooperative, continue to show interest. The Zug corporation is planning a project in the city of Zug independently of the other landowners. How this will look is still open.

  • Another skyscraper characterizes Zurich Oerlikon

    Another skyscraper characterizes Zurich Oerlikon

    The foundation stone for the project was laid in 2014 with a multi-stage general planning competition. Armon Semadeni Architects, Zurich emerged as the winner. SBB is investing around 96 million francs in the Franklinturm at Zurich Oerlikon station. The almost eighty meter high new building will have 14,800 square meters of office space on 21 floors and shops and restaurants on the ground floor on 200 square meters. In addition, a bicycle ramp will be integrated into the Franklinturm, which will connect Hofwiesenstrasse with the Velostation Passage Oerlikon. The sales and catering areas on the ground floor will be marketed in 2021. With the project, SBB wants to further improve the quality of work and life in Zurich Oerlikon. The building, together with the Andreasturm, will have a significant impact on the cityscape in north Zurich, emphasize those responsible for the project. As with previous SBB buildings, the Franklinturm will also be realized according to the "DGNB / SGNI Platinum" standard of the Swiss Society for Sustainable Real Estate Management. The system evaluates the ecological, economic, socio-cultural and functional qualities of a building. ■

  • Wolkenkratzer sollen Solarstrom produzieren

    Wolkenkratzer sollen Solarstrom produzieren

    Gebäude gehören zu den grössten Energieverbrauchen. In Europa sind sie für ungefähr 40 Prozent des Stromverbrauchs und für 36 Prozent des CO2-Ausstosses verantwortlich, wie Venture Kick in einer Mitteilung schreibt. Insbesondere hohe verglaste Gebäude verbrauchen viel Energie. Im Sommer müssen sie aufgrund der grossen Fenster stark gekühlt und im Winter stark beheizt werden. Das Tessiner Jungunternehmen iWin will diesem Problem entgegenwirken.

    Die Firma arbeitet an einer Lösung, mit der vor allem grosse Gebäude mit Glasfassaden selbst erneuerbare Energie produzieren können. Konkret entwickelt sie spezielle Jalousien, welche als Photovoltaikanlage fungieren. Die zugrundeliegende Technologie wurde bereits an der Fachhochschule der italienischen Schweiz (SUPSI) validiert und zum Patent angemeldet.

    Die Jalousien von iWin sind den Angaben zufolge in einer Isolierglaseinheit versiegelt. Ein Vorteil der Lösung ist, dass sie nicht nur zur Energieproduktion dient, sondern gleichzeitig auch einen Licht- und Sonnenschutz bietet. Ausserdem stört sie die optische Erscheinung des Gebäudes nicht und kann auf einer grossen Fläche installiert werden.

    Mit seiner Entwicklung konnte das Start-up nun die Jury von Venture Kick überzeugen. Es gewinnt einen Förderbeitrag in der Höhe von 150’000 Franken. Damit will es die Entwicklung eines anwendungsfähigen Produkts vollenden, sodass es mit dem Verkauf starten kann.

  • Helvetia invests in the RhyTech quarter

    Helvetia invests in the RhyTech quarter

    The RhyTech quarter, which consists of two high-rise buildings, an apartment building and the converted historic Hall 22 of the former Alusuisse area, is intended to combine public and private uses, said Halter AG in a press release . The Zurich-based construction company will implement the RhyTech quarter as a general contractor. Construction work is scheduled to begin in November this year. Completion and occupancy of the quarter are targeted for the first quarter of 2024.

    The general contractor Helvetia Versicherungen was able to win over an investor for the smaller of the two high-rise buildings. The insurance company will realize the planned apartments as rental apartments and also market the restaurant on the 17th floor, explains Halter. "The project is perfectly tailored to the market environment and offers a sustainable investment in an up-and-coming community in the Schaffhausen region", Daniel Wehrli, the responsible project manager at Helvetia, is quoted in the press release. According to her, a tenant has already been found for the restaurant in the high-rise.

    The second high-rise and the apartment building are designed as condominiums. Of the 96 condominiums in the high-rise building, 39 and around a quarter of the apartments in the multi-family house are already taken, writes Halter. In view of the reference date, which is around three years away, this is "a very good reservation status", says Halter CEO Markus Mettler. In addition, Halter has already been able to win Migros as anchor tenant for Hall 22.
