Our multidisciplinary design team brings together the expertise of British practice Sergison Bates architects, acting as lead designer, and French architecture studio Atelier Hart Berteloot. Their thorough experience regarding reuse, domesticity and social housing in (sub)urban contexts forms the basis of a rich and complementary collaboration.

The team is strengthened by Richard Klein architectes, architect-historian, whose in-depth knowledge of architectural heritage enables a sensitive and informed reading of the existing building. Their contribution strongly informs a design process in which respect for the original spirit of the building is reconciled with pragmatic and carefully considered design proposals.

Atelier Jean Chevalier brings a wider vision to the team, proposing landscape strategies at the scale of both the site and the neighbourhood, grounded in a nuanced understanding of history, territory and local social dynamics.

Courtoisie Urbaine takes the lead on the development of new activities in the plinth, working out sustainable and long-term operational models. Their approach is based on active immersion in the social landscape and existing networks, ensuring proposals that respond to the needs of future residents, the inhabitants of La Grâce de Dieu and occasional visitors alike.

Espace Temps provides the team with technical knowledge. They develop efficient, responsible and sustainable solutions, both in terms of maintenance and circularity. EVP Ingénierie takes on the structural engineering, working with rigour and precision to optimise interventions while preserving the integrity of the existing load-bearing system.

Cost consultant Becquart Économiste carries out detailed financial assessments from the earliest design stages.

Finally, the collective intelligence of the team is enriched by the knowledge, experience and enthusiasm of local residents. Through regular workshops, the production of physical models and shared digital tools, the team continually exchanges ideas and refines its proposals, taking into account ambitions at multiple scales: addressing local needs, articulating a resilient vision in response to climate challenges, and developing innovative solutions with national relevance.

Rehabilitating the Langevin building means transforming what already exists into a catalyst for the future. It is about uncovering the potential of a neglected structure, asserting its heritage value and using it as the foundation for a renewed way of living—more open, more equitable, rooted in history and oriented toward the future.

The project is grounded in principles of reuse and revalorisation, engaging with an architecture that has long been overlooked and undervalued. Rather than accepting this disregard, the project proposal embraces it as an opportunity: to reveal the building’s heritage character, to re-establish it as a living witness to its time, and to showcase a renewed architectural language and purpose.

By gaining a thorough understanding of the original construction system—its logic, structure and load-bearing capacity—the project can explore carefully considered transformation scenarios. At every scale, the design process is guided by the idea of working with what is already there. The ambition is to shape the building’s future from its existing qualities, highlighting the ingenuity of the architects, engineers, landscape designers, technicians and workers who contributed to its making.

Embedded within active social networks, the project builds on local dynamics and shared uses to restore connections between architecture, residents and the wider territory.

The building’s heritage value is undeniable. Far from ordinary, it stands as a testament to a specific period that deserves recognition and care.

The approach is intentionally optimistic and places residents at the centre of the transformation, returning the building to a human scale—one defined first and foremost as a place to live.

The project rethinks the uses of the building’s plinth and anchors it in the landscape. It upgrades shared spaces, by providing ample landings and a communal roof garden for residents. It diversifies housing typologies and proposes a more permeable, open and generous living environment, in which the inherited structure becomes the framework for a renewed pleasure of dwelling.
