The project rethinks the concept of a modern residential building. “Sweden family” becomes a symbol of a residential building as a closed community, where the senior members of community look after the younger ones and where one can take paste time. The building is furnished with all necessary features, among which is the play school on the roof, the sports center and a small store with a café. Combination of several types of flats and public facilities turn the house in a friendly community. The form of the house varies depending on the climate and cost of the project. A special material, warm concrete, is being developed for this series.
