A precedent for collective housing design by Riken Yamamoto, demonstrating how modular concrete frames, external circulation, and a shared central courtyard can foster community interaction.
- What we like about this project
- The light, vaulted metal roofs contrast sharply with the heavy, monolithic concrete frames below.

- courtyard-housing
- Geometry
- A series of repeating, multi-story concrete frame blocks arranged in a linear sequence. Each block features a modular grid of balconies topped by a distinctive curved, vaulted metal roof canopy.
- Facade system
- Open concrete frame structure with recessed glazing, metal railings, and integrated external staircases.
- Structural guess
- Reinforced concrete post-and-beam frame with cantilevered floor slabs.
- Spatial scale
- Medium-density, multi-family housing scale, rising five stories above the shared courtyard.
- Lighting
- Bright, diffused daylight under a lightly clouded sky, casting soft shadows beneath the concrete slabs and curved roof canopies.
- Atmosphere
- An orderly, community-focused residential atmosphere where domestic life spills onto open-air balconies.
- Environmental context
- An organized residential complex bordering a central lawn with young, slender trees planted along a stepped concrete plinth.
- Spatial experience
- The residential blocks face a shared central courtyard, with ground-level stairs and open-air circulation creating a highly social, porous transition between public green space and private units.
- Composition rhythm
- A strong diagonal perspective created by the rhythmic repetition of identical concrete housing blocks stepping back into the distance.
