Set at the heart of the Federation's technical site, the new Timber Welfare Building dedicated to waste collection staff answers a long-standing need: a facility that is dignified, comfortable, and suited to the scale of the teams who keep the city running every day. Designed to accommodate up to 200 staff, the building houses 7 changing areas, 4 individual shower zones, and 7 sets of sanitary facilities, organized around a sequence of communal spaces conceived for exchange and conviviality. True to the demands of new construction, the building is adaptable, demountable, expandable, and modular—in short, capable of accompanying any future evolution of its services.
Its design follows a bio-based, low-carbon approach. The structure is mixed, with wet cores in concrete and the overall frame in timber, distinguished in particular by the use of massive timber slabs for the floors and roof. These remain exposed and help define the character of the spaces. The interiors cultivate a sense of familiarity, hygiene, privacy, warmth, and comfort—essential qualities for a building that also serves as the staff's only indoor workspace.
The spatial organization relies on a plan symmetrical along two axes, a compact volume, and optimized circulation flows, ensuring rigorous functionality. The spaces unfold along an east-west axis, whose center is marked by double height and a zenithal skylight. Externally, the Timber Welfare Building sits within a wooded fringe in contact with Strasbourg's green belt. It is clad in timber, with varying rhythms of cladding underscoring a composition of horizontal strata generated by the two peripheral glazed bands. The façade becomes a tool that is as aesthetic as it is functional, allowing for generous natural light, passive ventilation, and the preservation of interior privacy.
