In Montpellier, a city in the southern French department of Hérault, the CCAS of Montpellier — a local social services organization — completed in 2026 the Espace Ambroise Croizat, a public space designed to encourage social interaction and inclusion. The project, carried out by the architecture firm TAUTEM, spans 1,370 square meters of usable floor space, with an additional 1,205 square meters dedicated to a garden. The total cost of the construction was 3.6 million euros, excluding taxes, according to a press release. The Espace Ambroise Croizat is located between the Arceaux and Figuerolles neighborhoods and was created by transforming the former Centre d'expérimentations et d'innovation sociales (CEIS) into a space focused on care, dignity, and social support. The design is tailored to the Mediterranean climate and honors the site’s history, offering a range of services such as a social support center, a digital hub, a community kitchen, and a shared garden. The site had a long history, once housing a nursery and undergoing various transformations over the years. Instead of demolishing the old structures, TAUTEM worked with the existing buildings, highlighting their architectural value and incorporating them into the new design. From the street, the restored facades, entrance, and copper sign give the building a visible and assertive presence while engaging with the surrounding structures. The solidarity grocery store is positioned beneath the restored arches, creating a welcoming base that connects the space with the city. On the garden side, the extension wraps around a cooling island, creating an open and flexible outdoor space. The design includes an open porch that serves as a gentle transition between the public area and the reception zone, enhancing the sense of accessibility and comfort. The building features a low-carbon concrete structure with vaulted ceilings that reinterpret the architectural forms found in the nearby Arceaux neighborhood. This design allows for flexibility and future adaptation of the space. The wooden facades, placed under the vaults, complement the more rigid concrete elements, contributing to a warm and enduring aesthetic. The integration of vegetation, natural light, and climate-responsive features ensures that the space is both comfortable and environmentally conscious. The shared garden preserves existing plants and features, while the corridors, vaulted ceilings, and wooden facades create a design that is sensitive to the local climate and promotes collective use. The project emphasizes sustainability and the reuse of existing materials. By preserving the original structures, using low-carbon concrete, and incorporating biodegradable materials, the design follows a principle of "constructive and climatic sobriety." The use of solar panels contributes to achieving a BEPOS (Net Positive Energy Building) status, meaning the building produces more energy than it consumes. The attention to detail in the design, including the use of natural light, materials, and spatial proportions, reflects a commitment to creating an environment that supports both staff and visitors. Through the Espace Ambroise Croizat, TAUTEM Architecture demonstrates that spaces serving marginalized communities can be designed with the same care and quality as any cultural or institutional building. Here, the quality of the space becomes a tool for healing, support, and inclusion.
