Located in the heart of Paris’s 8th arrondissement, in close proximity to the Arc de Triomphe, the project at 52 avenue Hoche involves the construction of an office complex of nearly 12,000 m², designed by FS Braun & Associés. Conceived as a high-performance and contemporary building, it meets demanding thermal requirements and is part of an HQE (High Environmental Quality) approach. The project notably incorporates semi-transparent photovoltaic sunshades on the façade, combining energy production with dynamic solar protection.

Following a detailed thermal analysis of the existing building, the project evolved toward the creation of a new “open-book” volume, located at the corner of rue Beaujon and avenue Hoche. This intervention is accompanied by the reconstruction of the 18th-century pavilion at the rear of the courtyard, transformed into a meeting space, in an approach that reconciles heritage with contemporary architecture.

In this context, the choice of ACRYTHERM® monolithic slabs with a stone-textured finish, combined with the Portland color, anchors the project in material continuity with the existing architecture. The mineral tone and texture of the façades extend the palette of the reconstructed pavilion, contributing to a harmonious integration of the whole while asserting a contemporary architectural expression. The building envelope was the subject of a comprehensive approach to insulation, both in the design of openings and in the selection of materials.

Within this framework, Rebeton designed and manufactured the ACRYTHERM® mineral slabs for façade and flooring applications, fully bespoke to meet the complexity of the project. The project also includes the development of specific components, such as bespoke drainage slabs and planters, designed to meet the building’s technical and functional requirements, particularly in terms of water management and landscape integration.

This project illustrates Rebeton’s ability to contribute to complex developments combining façades, flooring, and technical elements, by delivering bespoke mineral solutions in support of demanding, durable, and context-driven architecture.
