The rehabilitation project of the Carré Champerret real estate complex in Levallois-Perret, led by Baumschlager & Eberle Architekten Paris, is part of an urban revitalization and architectural renewal strategy for the Louise Michel district, located at the gateway to Paris. This 1980s building, consisting of four blocks arranged around a central garden, is being transformed to meet contemporary requirements while preserving and enhancing the qualities of the original construction.

The architectural intervention aims to provide the building with a renewed and distinct identity, establishing it as an emblematic urban landmark at the entrance of Levallois-Perret. The design of the new façades restores a rhythm of full-height glazed openings to maximize natural light, while opaque sections are constructed using insulated double-brick walls.

The ground floor, open and adaptable, features a spacious two-level central lobby, a coworking area with a restaurant, as well as a lobby and lounge on the garden level. This configuration enhances circulation fluidity, with a redesigned central hall that is both identifiable and open to the street.

The compact volumes optimize energy efficiency by limiting glazed surfaces to essential areas. Circulation spaces have been reconfigured based on the existing cores to distribute the different office blocks via transparent landing's setback from the street. This arrangement differentiates the building’s various volumes and improves movement within the complex.

Within the inner courtyard, the building’s curved forms frame a central garden, providing users with visible green spaces from the office floors.

The façades facing both the street and the courtyard are treated with a consistent architectural language, featuring a subtle interplay of different modulations, including varied brick cladding depths, staggered patterns, and precise alignment. Several shades of eco-friendly bricks were selected to minimize the carbon footprint of the façades while maintaining a durable design and tested technical solutions.
