the ‘32.4° house’ in japan is an intriguing sight from the outside. this project began with a unique design process. ‘the largest possible square floor plan was first drawn within the almost square lot of the house,’ architect akio nakasa explains. ‘then, a slightly smaller square plan was drawn inside the outer square, and rotated around the center of the square clockwise by 32.4 degrees, creating four right triangles inside the outer square.’

 

but why? it’s actually a clever solution to stay under budget and to satisfy the statutory building coverage ratio, plus a number of interesting spaces and features resulted from this. the home-inside-a-home creates a sort of internal courtyard, which even includes a tiny car park.

the sections not part of the inner square are left open. sun shines down these chasms and reflects defused light into the inner living spaces. while the outer square of the home has very few windows, the only view available to the residents is that of the exterior white walls; yet, without anything picturesque to look at, this doesn’t seem like much of a shame. akio nakasa of naf architect & design orchestrated this sleek building to have sharp edges for a distinct impression; aside from the white of the walls, the only other color is the soft brown of wood. the interior spaces play with the angles created as a result of the superimposing of geometric shapes — a dissection of a typical house typology.
