Toyo Ito

Pritzker Laureate Toyo Ito’s Japanese public works are characterized by a structural weightlessness, where hollow, organic column cages double as vertical circulation and sweeping concrete arches taper to impossibly slender points as they meet the ground. This portfolio serves as a vital reference when detailing how complex diagonal facade lines can transition seamlessly into a continuous roof skin, or when designing civic spaces where structural elements must double as light wells and utility runs.

An interior precedent showing how a structural, tree-like concrete envelope can define interior circulation and frame dynamic urban views, integrating structure and facade into a single spatial experience.

What we like about this project
The way the timber stair treads precisely follow the faceted, non-orthogonal geometry of the interior partitions.

Geometry
The space is defined by a structural concrete perimeter wall with organic, branching, tree-like openings that form irregular, non-orthogonal windows. A central staircase with timber treads and landings winds through the volume, flanked by faceted geometric partitions and thin metal handrails.
Facade system
Structural concrete load-bearing wall with integrated, custom-shaped glazing units.
Structural guess
Load-bearing reinforced concrete exterior wall acting as a structural tube with integrated glazing.
Spatial scale
A multi-level interior circulation zone with human-scaled stair flights and landings integrated within a larger commercial envelope.
Lighting
Diffused daylight enters through the large, irregular structural openings, casting soft shadows on the timber stairs and concrete walls.
Atmosphere
A bright, structurally expressive interior where the boundary between architecture and the city is blurred by organic voids.
Environmental context
An urban street intersection in Tokyo is visible through the structural glazing, showing pedestrian crossings, roads, and neighboring buildings.
Spatial experience
Descending the stairs offers dynamic, shifting views of the Tokyo streetscape through the branching structural apertures. The heavy, solid concrete envelope is dematerialized by the irregular voids, creating a complex interplay of light, shadow, and urban connection.
Composition rhythm
The diagonal lines of the stair handrails contrast with the organic, branching diagonals of the concrete structural openings.
