Voids and Vertical Space Reinterpret Traditional Japanese Machiya on a Compact Site in Tokyo

Takumi Wakui + Riho Wakui Architects have designed a four-story wooden residence in Kagurazaka, Tokyo, reinterpreting the traditional Japanese machiya for a compact 33 sqm site. The project focuses on integrating daylight, natural ventilation, and spatial openness within a dense urban environment.

The design draws inspiration from the historical context of Edo-period urban subdivisions, characterized by narrow-fronted townhouses. To address the small footprint, the architects organized the residence vertically, extending the spatial experience upwards. Each floor has a distinct function, with programs transitioning from public to private on upper levels, separating activities without relying on traditional partition walls.

A series of voids visually and spatially connect the floors, creating a continuous volume. Large openings above the living room and in the top-floor bathroom allow natural light to penetrate deeper and frame views of greenery. Projecting side walls on the exterior shield interiors from sunlight and capture prevailing breezes.

The structural system features a robust truss along the exterior walls and a double-wall spine at the building's center, providing stability and flexibility for floor arrangements and future expansion. Openings and voids establish connections between interior and exterior spaces, as well as between levels, distributing areas for occupation that respond to changing daylight, airflow, and seasonal conditions.
