Boligbyggelag are cooperative housing associations primarily found in Norway. They are established to facilitate the construction and management of residential properties for their members. Members typically buy shares in the association, which gives them the right to live in a specific apartment or house. These associations aim to provide affordable housing options and promote community living. By pooling resources, members can benefit from lower construction costs and shared maintenance responsibilities. Boligbyggelag also often engage in long-term planning to ensure sustainable living environments for their residents.
