We do love showing small modern houses and the Japanese excel at them; this one is interesting because the architects appear to have placed it on the lot so oddly and inefficiently, to site it exactly 63.02° from the road, apparently to open up the interior to more natural light.
The Schemata Architecture Office says:
63.02°is built on a built up area in Tokyo. This small building is used as SOHO and an apartment for rent.
"This building is cut on the axis line inclined to a front road by 63.02°. The window in this building concentrates there. You can see the intersection by seeing the outside through the windows."
The interior can be described as minimalist.
Sometimes, perhaps one can be too minimalist for comfort.
