  • Kriens: Old brickworks to shine in new splendour

    Kriens: Old brickworks to shine in new splendour

    The Old Brickworks below Bellpark in Kriens is well-known in the city. It was built during the economic boom at the end of the 19th century. Between 1889 and 1899, Lucerne expanded its housing stock by 25 percent, and the demand for fired bricks was high. However, insufficient clay deposits and unsteady management led the brickyard into bankruptcy in 1900.

    After several changes of ownership, the building was converted into a residential house in the 1920s. Since then, it has undergone several structural changes and has grown historically as a result. In the meantime, it has been included in the list of buildings worthy of protection in the Canton of Lucerne. Until recently, young families, creative people, craftswomen and artists lived and worked in the Old Brickworks.

    The building is in great need of renovation. As the landowner, Schmid Immobilien AG decided to redevelop the Alte Zieglei and develop a building project in an accompanied process.

    The Alte Ziegelei is well-known in the city and has been in Kriens for over 100 years.

    An expert committee consisting of representatives of the client, the preservation of historical monuments and the city of Kriens as well as external architects and engineers evaluated the project designs of four invited architectural teams. The projects were to fulfil the reference to the history of the Old Brickworks, implement the interests of the preservation of historical monuments and take into account the economic interests of the owner. The winning project was designed by Seiler Linhart Architekten from Lucerne.

    It envisages the removal of the historically grown three-sided extensions to the building and the reconstruction of the Old Brickworks to its core. The historic façades are to be renovated and the central element of the naturally lit inner courtyard restored. On the east and west sides, the residential building is to be supplemented with an arcade construction. A total of 18 flats are planned, distributed over the three upper floors, and four studios on the ground floor. Even after the renovation, the focus will be on communal living under one roof in the Old Brickworks.

    Construction work will start in spring 2023 and should last until the end of 2024. The investment amounts to around eleven million Swiss francs.

  • Total renovation and new construction in record time

    Total renovation and new construction in record time

    The Hagenmatt housing estate in Root, with around 160 flats, is a good example of successful total renovation and redensification: the estate, built in the 1970s, offered ideal conditions for this project. For the implementation, Die Liegenschaftsverwalter AG, representing the owner Schürch Immobilien AG, engaged PP Baumanagement AG from Kriens for the overall project management, cost planning and construction management. In addition, six new buildings with a total of fourteen terraced detached houses and fourteen 2.5-room flats in timber construction were realised by Strüby Konzept AG from Seewen SZ on behalf of the owner.

    In addition to a more attractive design of the flats, the renovation also aimed at optimising the building’s appearance, redesigning the outdoor spaces and optimising energy efficiency. The latter was achieved thanks to technical measures such as triple-glazed windows and a connection to the EWL district heating system, as well as switching off the oil-fired heating system. For more living comfort, underfloor heating was installed in the existing property, the balconies were extended, the kitchens were equipped with new appliances and the wet rooms were renovated.

    The newly built single-family and multi-family houses are all two-storey and blend in harmoniously with the previously underutilised areas. They feature Minergie-compliant building envelopes, green flat roofs, generously designed roof terraces, and large windows that ensure that the houses are flooded with light. The total renovation of the Hagenmatt development and the construction of the six new buildings was completed in stages within eight months.

    The fast construction time – especially for the new buildings – is due to the chosen timber construction: The components are delivered to the construction site prefabricated, so that assembly can begin directly on site. The Strüby companies purchase around 20,000 cubic metres of wood per year directly from Swiss forest owners. The wood is sawn and glued in the respective region before it is processed further. Thanks to these short distances, grey energy is significantly reduced.

    In addition to the short construction time, the owner of Die Liegenschaftsverwalter AG, Andreas Gasser, is proud that the project’s total cost budget of 42 million Swiss francs could even be undercut. Moreover, the quality of living for the tenants, who were not yet affected by the conversion in the first stage, was not restricted at any time. Gasser emphasises that by cleverly increasing the density by adding storeys, extensions or supplementary buildings, it was possible to create more living space on existing areas and at the same time curb land wastage.
