Anne Lacaton and Jean-Philippe Vassal

This Pritzker Laureate practice, working across Paris, Bordeaux, and Cap Ferret, establishes a distinct visual identity by pairing ultra-lightweight, translucent glass and corrugated metal envelopes with raw structural elements, allowing domestic life and natural elements to dynamically alter the building facades. This portfolio serves as a vital reference for detailing high-performance, low-cost envelopes in multi-family social housing and cultural centers, particularly when designing thin-slab structures that utilize movable fabric awnings, industrial greenhouse components, and integrated preservation strategies to maximize interior volume.

The concrete facade of the Nantes School of Architecture by Lacaton & Vassal, featuring external ramps and a roof deck.

A precedent for institutional architecture that utilizes a raw concrete structural frame and external circulation ramps to create a highly flexible, open, and public-facing educational facility.

What we like about this project
The roof level functions as a fully accessible public plaza or viewing deck.

Geometry
A long, horizontal concrete frame structure with a prominent, gently sloping ramp system that wraps the upper levels and roof. The facade is organized in clear horizontal bands with deep floor plates.
Facade system
Glazed curtain wall system set back within a deep, open concrete frame.
Structural guess
Reinforced concrete column-and-slab frame with long spans.
Spatial scale
Large-scale institutional building, roughly three to four double-height stories, with visible human figures on the roof deck establishing scale.
Lighting
Bright, direct daylight casting soft shadows under the deep concrete floor slabs.
Atmosphere
An open, active, and unpretentious educational hub integrated with its urban landscape.
Environmental context
Set back from a paved street with a row of young deciduous trees providing a soft green buffer in front of the open ground level.
Spatial experience
The building reads as an open, accessible infrastructure where circulation is pushed to the perimeter, allowing users on the ramps to look out over the city and park.
Composition rhythm
A strong horizontal grid of concrete columns and slabs, dynamically interrupted by the diagonal lines of the perimeter ramps.
Style reading
Industrial pragmatism and high-tech functionalism
