  • The Quai Vernets project in Geneva with 12,400 homes

    The Quai Vernets project in Geneva with 12,400 homes

    The Quai Vernets project in Geneva is a perfect example of forward-looking urban development focused on sustainable living spaces. This diversity of housing options contributes to an inclusive community based on the principles of the social and solidarity economy.

    The collaboration between the pilot companies Losinger Marazzi and Pillet SA, the eight developers of the ENSEMBLE team and the local authorities has resulted in a unique neighbourhood, unrivalled in Switzerland, that stands out for its innovative and sustainable character. The project is part of the PAV programme and aims to redefine the concept of “living in the city”.

    Historically, the height of buildings in Geneva has been between 18 and 24 metres. In the PAV, however, they start at 30 metres, and a residential building on the site planned for the barracks will be 80 metres high. Even so, this is still “low” compared to the office towers that will be built in the planned “Étoile” business district. These will be up to 175 metres high, making them the tallest buildings in Geneva.

    In a city with the lowest housing vacancy rate in Switzerland, it makes more sense from an urban planning point of view to have housing and service businesses in close proximity to the centre rather than garages and factories. Half of all construction projects are expected to be completed over the next twenty years. This will depend on the economic situation and changes in demand for housing and workspace.

    When building projects are implemented, the canton is in the boat, with the exception of public infrastructure. It puts building plots out to tender as part of the allocation plans, after which investors can apply for a specific project. Long-term leases are awarded by the cantonal government. The next stage is planning on the barracks site, which is currently still used by soldiers. A neighbourhood comprising several residential blocks, a school building and an office complex is planned. It will probably take half a century to redevelop the whole town.

    As well as creating housing, the project also includes sustainable infrastructure measures such as rehabilitating the banks of the Arve and converting a car park into a tree plantation. These measures will not only promote biodiversity, but also enhance the quality of life in the new district. Intensive cooperation between all the partners involved will ensure that the project blends seamlessly into the existing urban environment.

    The commitment to environmental awareness and sustainable construction methods is another key element of the project. Losinger Marazzi demonstrates by example how resources are used responsibly through the recycling of materials and the choice of sustainable technologies and methods. The provision of 3,000 bicycle parking spaces and the creation of pedestrian zones also underline the commitment to soft mobility.

    Overall, the Quai Vernets project shows how visionary planning and cooperative collaboration can give rise to a viable and liveable neighbourhood that meets the requirements of modern, sustainable and socially inclusive urban living.

  • Modular living for four generations

    Modular living for four generations

    Geneva society is facing a major challenge. The existing housing stock is not sufficient to meet the growing needs of an ageing population. The current housing stock is designed for a three-generation society and does not take sufficient account of the specific requirements of a four-generation society. This change means new housing requirements, such as flexible room layouts, barrier-free access and temporary spaces for guests or carers.

    A flexible housing prototype
    To meet these requirements, a consortium comprising public services, architects, property consultants, construction and energy engineers, building cooperatives and experts in social housing and socio-medical services is working on an innovative housing prototype. The prototype is designed to be flexible in use and to take account of the housing needs of all age groups. The adaptive elements of the model can be applied to different types of building and should highlight cross-sectoral synergies in the areas of health, housing and costs.

    Land resources and innovation laboratory
    Finding suitable land is a particular challenge in Geneva, where land resources are scarce. Identifying and using suitable land is therefore a central element of the project. In addition to developing the flexible housing prototype, a temporary laboratory hall will be created. This hall will serve as a platform for experimentation, discussion and the display of architectural models. It will be available to project participants and the general public, and will encourage discussion and consensus-building within the project.

    A look into the future
    The Geneva project shows how cities can adapt to demographic change and develop innovative housing solutions. The flexible housing prototype and accompanying innovation laboratory are pioneering approaches to adapting housing to the needs of an ageing society while making efficient use of limited land resources. This initiative represents an important step towards improving the quality of life for all generations and creating sustainable and viable housing models.
