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.

A precedent for the radical transformation of modernist social housing, demonstrating how adding lightweight wintergardens and glass balconies can completely open up a heavy concrete tower facade.

What we like about this project
The contrast between the ultra-lightweight glass tower and the heavy, unfinished concrete building under construction to its left.

Geometry
A tall, rectangular slab tower defined by continuous horizontal bands of glass balconies and wintergardens, contrasting with the heavier, punched-window masonry blocks in the foreground.
Facade system
Non-loadbearing glass and aluminum wintergarden extension system.
Structural guess
Concrete frame with cantilevered steel/aluminum balcony extensions
Spatial scale
A multi-story high-rise residential tower (approximately 17 stories) viewed from a pedestrian-scale street level.
Lighting
Overcast, diffused daylight providing even illumination across the glass facades and minimizing harsh shadows.
Atmosphere
A calm, overcast urban scene where the lightweight glass tower brings a bright, modern presence to the neighborhood.
Environmental context
Set within an urban residential enclave in Paris, framed by older masonry apartment buildings, street trees, and pedestrian infrastructure.
Spatial experience
The tower rises as a light, highly glazed volume behind a screen of mature deciduous trees, offering a sense of openness and transparency compared to the traditional solid urban fabric nearby.
Composition rhythm
Strong horizontal rhythm established by the repeating floor plates and continuous glass balustrades.
