I.M. Pei

The portfolio of this Pritzker Laureate, spanning monumental cultural institutions in Boston, Syracuse, and Washington, DC, is characterized by a tense dialogue between razor-sharp, precise geometric masses and the highly tactile, board-formed or bush-hammered textures of their concrete and stone surfaces. This body of work serves as a vital reference when detailing the structural expression of vast public atriums, particularly where massive concrete blocks must appear to float effortlessly over multi-story voids or where delicate, curved glass walls intersect rigid orthogonal frames.

A premier precedent for Brutalist civic architecture, demonstrating how massive board-formed concrete can be sculpted with dramatic cantilevers and large-scale voids to frame views and reduce visual weight.

What we like about this project
The way the massive upper concrete block appears to float effortlessly over a multi-story open-air void.

Geometry
A massive, sculptural concrete volume featuring a dramatic, high-level cantilevered block supported by a thick vertical pier, creating a large, open-air void or 'window' in the building's upper profile.
Facade system
Exposed structural concrete walls with deeply recessed ribbon glazing.
Structural guess
Reinforced concrete core and deep cantilevered concrete girders.
Spatial scale
Monumental civic scale, towering over the pedestrians walking on the pathways below.
Lighting
Bright, direct daylight casting sharp shadows that accentuate the deep recesses, cantilevered volumes, and the texture of the concrete.
Atmosphere
A striking contrast between heavy, permanent concrete geometry and the soft, changing textures of the surrounding nature.
Environmental context
Situated on a grassy slope surrounded by mature deciduous trees, adjacent to older brick campus buildings.
Spatial experience
The building acts as a monumental gateway or frame, where the massive concrete forms frame views of the sky and landscape through a giant elevated void, contrasting heavy mass with empty space.
Composition rhythm
Asymmetrical balance where a heavy, solid vertical tower on the right supports a massive horizontal bridge that floats over a large open void.
