Bjarke Ingels Group (BIG) has designed an apartment block in Copehagen for Lejerbo, a nonprofit social housing association that rents accommodation to lower-income residents. The prefab, modular design, covered with timber planking opens up small balconies and floor-to-ceiling windows for all, creating a new model for affordable housing that promotes wellbeing. Named ‘Dortheavej’ after its address in the north western area of Copenhagen – an area of car repair shops, storage units and 1930-50s industrial buildings – the five storey residence features 66 apartments ranging from 60 to 115 sq m in size. Founded by Danish urban space designer Jan Gehl, Lejerbo’s mission is to bring ‘homes for all’.
