An interplay of several green triangles on a steel structure articulates the intermediate liminal spaces between the interior and exterior of the building. Architects delivered a three-story office and retail complex in the Minami Aoyama district of Tokyo in 2015.
The project is located on a hilly 750 square meter site bordered by streets to the west, east and north, the last of which is a private driveway integrated into the overall design. The design also responds to the client’s request to create an “urban oasis” in the heart of the city.

The design primarily exploits these site conditions by referencing the geometry of the triangles, which vary in materiality, hue and density as they progress from the exterior to the interior. A two-story triangular void features hanging plants, incorporating greenery into the building and providing a visual connection to the adjacent main street through its glass curtain wall.
The retail and restaurant spaces are pierced by semi-open triangular balconies around the corners of the building. A triangular bridge connects the two areas of the complex, from which exposed beams intersect on the exterior to juxtapose the building with the landscape elements.
“In particular, the linear arrangement of mirrored stainless steel, LED light, flexible panels and glass in the lobby presents an infinite play of angular shapes, where natural light spills into the many vertical gaps and bounces off the striated and reflective materials,” These elements, combined with the surrounding landscape, are projected onto the glossy tiles of the façade and the glass curtain walls, as well as the mirror-effect stainless steel that covers the interior corridor, reinforcing the idea of interpenetration.
