Kazuyo Sejima and Ryue Nishizawa

This Pritzker Laureate practice defines its institutional and cultural spaces through radical geometries, utilizing absolute circularity, razor-sharp shifted metal volumes, and continuous glass walls that curve at the corners to dissolve traditional building fronts. The resulting portfolio serves as a vital reference for detailing seamless glass envelopes and undulating floor slabs that lift or bend upward to form interior landscapes, especially when designing low-profile public pavilions that must integrate softly into forested contexts and historic city grids.

An aerial precedent demonstrating how a large-scale contemporary museum can be integrated into a historic urban park using a low-profile circular glass pavilion and scattered gallery volumes.

What we like about this project
The absolute circularity of the building contrasts sharply with the irregular, organic shapes of the surrounding tree canopy and the traditional city grid.

Geometry
A low-slung, perfectly circular glass pavilion acts as a continuous base plate, from which several rectilinear white gallery volumes of varying heights and proportions emerge.
Facade system
Continuous structural glass curtain wall wrapping the circular perimeter.
Structural guess
Slender steel columns supporting a flat roof plate with independent concrete gallery boxes.
Spatial scale
A sprawling, low-profile public building that maintains a low, human-scaled horizontal datum despite its large footprint.
Lighting
Soft, diffused daylight under an overcast sky, casting gentle shadows and highlighting the white volumes against the dark green tree canopy.
Atmosphere
A serene, floating composition where heavy gallery boxes appear to float within a transparent circular ring.
Environmental context
Set within a lush, forested urban park in a mid-rise Japanese city, with distant mountains framing the background.
Spatial experience
The building reads as a transparent, non-directional pavilion nestled within a dense urban park, allowing the surrounding city and greenery to visually penetrate the ground floor.
Composition rhythm
An array of rectangular white blocks arranged dynamically within a perfect circle.
Style reading
Japanese minimalism and SANAA's signature light, transparent architecture
