A steel constructed house project has started in a traditional wooden residential built up area in Sumida ward. The client is a single woman in her twenties who brought up locally. With her attachment, she offered a residence to live with her parents with a precept of rebuilding the central room.

With 31.99sqm site area and 19.08sqm building area being extremely narrow, in order to hold sufficient inner scale, thin pre-manufactured LGS panel was inserted systematically which nullified the field wielding at comparatively low price. The studied minimum wall thickness allowed the inner space to be maximum.

Much alike previous SEVEN, vertical “one-room” is based on central stairwell. Given the condition of 3 bedrooms placed in each floor, MINI secures private. In limited space of 3.3sqm void and terrace overlaps and creates comfortable space and profundity
