Rooflight patio & restaurant - CIRN Nanterre

An urban transformation in the heart of greater Paris

In Nanterre, on the edge of La Défense business district, a former office building is being reborn as a vibrant student residence with 500 units. This ambitious redevelopment responds to the growing demand for affordable student housing while reimagining the use of an entire urban block.

The inner courtyard becomes a lively, multifunctional space — a luminous glasshouse structure that shelters shared facilities such as a restaurant, fitness area, and relaxation zones. Bathed in natural light, this central atrium creates a serene connection between greenery, community, and contemporary architecture.

Architecture of transparency and precision

The project stands out for its structural complexity: several interconnected glass roofs supported by a steel framework integrated into the existing concrete shell. The precise assembly of steel, aluminum, and glass results in a fluid, transparent, and energy-efficient space.

The varying roof slopes and the connections to inclined façades posed significant engineering challenges — met through meticulous coordination across design, fabrication, and on-site installation.

Sustainability and well-being

Designed according to the latest energy standards, the glasshouse features double glazing, thermally broken profiles, and natural ventilation to ensure optimal comfort and efficiency. The staggered façades create a soft, domestic atmosphere, reinforcing openness and a sense of place.

This oasis of calm within a dense urban fabric reflects an architectural approach where functionality, aesthetics, and sustainability come together in perfect harmony.

Engineering light and space

With this project, Forzon demonstrates its expertise in the design of complex glass structures — combining technical innovation and architectural refinement to redefine the way we live and interact with our built environment.
