The environment at Hauskvartalet in Oslo and Eriksen Skajaa Architects have together designed an urban ecological residential projects with non-commercial rental housing in the existing buildings in Hausmannsgate 42 and in a future low energy building with natural ventilation and massive wood structure in Brenneriveien 1.

The buildings are linked by a centrally placed staircase and elevator and also shares many features: Communal Kitchen on the ground floor, small commercial premises with low rent for residents and cultural workers in the quarter, workshops, allotments on roofs, office spaces and because og the lack of private bathrooms in the apartments a spacious public bath in the basement. The project is a discussion on what the sustainable minimum dwelling is today and an examination of how to develop housing projects with a high degree of participation.
