Architecture, Building and Structure Design Selfors Housing by Hans-Petter Bjørnådal The house is a rehabilation of a 1960 modernist villa, which was partly destroyed by a prefabricated design in the 80's. Much effort has been made in making a modern design in respect of the 60's modernist design. The house is sentered around a central staircase which functions as a air ventilation between the different stories.
