Numabukuro Apartment

The apartment is located on a corner plot, sandwiched between a busy thoroughfare and a side street. The building is built right up to the site boundary on three sides. On the side that faces the neighboring buildings, the unbuilt land area – left over due to Tokyo planning regulations – is used as an entrance court.

The six-story apartment’s main structure (concrete frame/slab) is situated on the periphery of the building. The exterior wall steps back slightly – 65 mm (2.6 inches) – on each consecutive level up the building.

This structural configuration allows the interior layout to be divided freely. The core of each unit is an “interior room” with timber floors. Sliding doors allow this space to be opened or closed to the outer rooms, which feel more like balconies, thanks to the generous full-height glazing and tiled floor finish.

The inner pentagonal rooms are buffered from the noise of the street by these in-between spaces, much like a traditional engawa – peripheral corridor – within traditional Japanese houses.

The concrete structure also allows the exterior walls to have larger window openings. The outer room of each unit is designed to simulate, in the words of the architect: “a garden, when plants are placed inside; a study, when a desk and computer are placed there; or a bedroom when a bed is in the space.”
