Riken Yamamoto

The Pritzker Laureate’s work across Tokyo, Beijing, and Hakodate is defined by a radical transparency that exposes entire multi-story interior programs to the public realm, balancing these open volumes beneath light, vaulted metal roofs supported by remarkably slender steel columns. This portfolio serves as a precise reference for detailing civic administrative buildings and art museums where structural diagonal lattices must be layered behind glazed panels to dissolve the boundary between interior workspaces and sunken public courtyards.

Yamakawa Villa by Riken Yamamoto, showing an open-air wooden deck framed by white plaster piers under a mossy gabled roof.

Yamakawa Villa

Nagano, Japan · 1977

A precedent for a low-slung, open-air pavilion that uses heavy plaster piers and a deep gabled roof to frame horizontal views of the natural landscape, blending traditional Japanese spatial concepts with modern minimalism.

What we like about this project
The roof is heavily covered with fallen pine needles and moss, integrating the building envelope directly into the forest floor ecology.

Geometry
A low-slung, symmetrical pavilion structure with a wide, gently sloping gabled roof supported by thick, rectangular plaster-clad piers. The open-air platform is elevated slightly above the forest floor, creating a framed horizontal void through the building.
Facade system
Open-air structural frame with no glazed envelope.
Structural guess
Timber post-and-beam structure clad in plaster and wood trim.
Spatial scale
A single-story residential scale pavilion, with a low ceiling height that emphasizes the horizontal plane.
Lighting
Soft, diffused overcast daylight illuminates the forest background, casting gentle shadows under the deep roof canopy and reflecting softly off the dark, polished wooden floor.
Atmosphere
Quiet, damp, and serene, with the scent of wet earth and pine needles suggested by the moss-covered roof and surrounding forest.
Environmental context
Set in a quiet, wooded landscape in Nagano, Japan, with birch trees, low shrubs, and fallen pine needles covering the roof and ground.
Spatial experience
The structure acts as an open-air breezeway or pavilion, framing views of the surrounding forest. The deep roof overhang and solid piers compress the space vertically, while the open sides maintain a direct, unglazed connection to the landscape.
Composition rhythm
Symmetrical arrangement of thick vertical piers balancing the strong horizontal lines of the roof and elevated deck.
