The Growing House project transforms a former private home into a greenhouse, nursery, and educational center about Geneva’s native flora. It works carefully within the existing building: the basement and ground floor are preserved and repurposed, while a new glass roof unites all the volumes, replacing first-floor bedrooms. Its structure is designed to avoid interference with the existing building, while providing it with heat in winter and shade in summer.

The ground floor houses a classroom, a multifunctional space, a shop, and an office. The basement provides storage, technical facilities, changing rooms, and seed germination chambers. On the new first floor under the roof, a fully functional greenhouse with passive ventilation and rainwater collection produces thousands of native plant seedlings perfectly adapted to Geneva’s microclimate.

The adjacent garden becomes a public biodiversity hub, open to the neighbourhood and home to local species. Growing House is designed as a resource for the volunteers, residents, and organizations already working to green the city — offering a sustainable, locally rooted alternative to disposable imported plants, and a place where people can learn, contribute, and reconnect with the living city around them.
