Presented with an impossibly narrow slice of land in Tokyo’s Ota-ku suburb, architects Takuya Tsuchida and Kano Hirano of No. 555 came up with the HSK Subako (the owners’ initials plus “birdhouse”). Known for their tell-it-like-it-is brand of design, No. 555 create dwellings that celebrate everyday materials and allow the stuff of life to be on view.
The owners of this particular perch are a product designer and architect couple. And since the former needed a place to work from home and to store his many bikes, fishing rods, and other gear, the architects accommodated with an entry that doubles as a workshop and store room. Unable to build out, the architects built up: Each of the two stories has a loft. And they detailed the house with matching birdhouse-like covered balconies on the front and back that light the living space and offer the owners a broad outlook from their little domain.
