"Kestävä Kerrostalo" is a solid brick housing project to be built in Oulunkylä, Helsinki. Complete with natural ventilation and solid brick structure, the construction will start in 2021. The solid brick building method has been almost forgotten in the Finnish building industry. By example we want to encourage professionals to explore the possibilities of traditional construction. The house consists of 29 apartments with large balconies. In addition there will be a communal space, sauna and a commercial space on the ground floor.
