The building is defined by a continuous vertical wall which accommodates the units of this housing block. This element includes both the interior and exterior spaces in one definite form expressing the sense of protection around all aspects of domestic life and setting a large frame around it. Openings of various sizes on this wall provide viewpoints from the interior to the surroundings while they also function as frames which highlight moments of private life in different expressions that take place in different spaces both indoors and outdoors. Four different housing typologies are accommodated within this plain volume: a two floor house, one single bedroom apartment, three twin bedroom apartments and one large penthouse. The plurality of the apartment typologies brings diversity in co-living, thus reflecting the vibrant spirit of contemporary urban life.
