Architecture studio Celeste has designed a health center in a rural area of ​​historical significance in Tremblay, Val-Couesnon, a former French commune located in the Brittany region.

The new project, developed in collaboration with healthcare professionals, incorporates high-energy-performance environmental strategies, including photovoltaic panels and biomass heating, while also utilizing biosustainable materials, reflecting an environmental approach rooted in local agricultural practices. 

The health center designed by Celeste reinterprets the local agricultural context through a composition of elemental volumes with sloping roofs, discreetly integrating into the landscape and providing continuity with the existing structure. In terms of its layout, the space is organized around the patient's path, incorporating natural light into the interior to ensure comfort.

For its construction, wood was chosen for the structure, wall framing, cladding, and fiber insulation. Marmoleum, a material made from natural raw materials, was used for the flooring.

Project description by Celeste

Designing with Healthcare Professionals
The health center project in Tremblay, Val-Couesnon, France, arose from the desire to bring together the region's healthcare professionals in a single location, creating a facility that transcends its function to contribute to a broader reflection on the architecture of care.

Located in a rural area of ​​historical significance, the building draws on local agricultural typologies, reinterpreted through a composition of elemental volumes with pitched roofs. This approach seeks a discreet integration into the landscape and a continuity with existing built forms.

Developed in close collaboration with healthcare professionals, the project is organized around the patient's journey, clearly articulating the spaces and ensuring confidentiality and comfort. Attention to natural light and materiality contributes to defining a serene atmosphere, in keeping with the care spaces.

The environmental dimension structures the entire project. The timber construction, the use of biosustainable materials, and the integration of efficient energy systems meet the stringent requirements aligned with the RE2020 objectives for 2028.

Celeste is an architecture and urban planning studio founded by Gwenaël Massot in 2015, based in Rennes, France. It primarily operates in the Brittany region of France.

The studio's work reflects on the long term and permanence, exploring a restrained and contextual architecture that is attentive to the continuities of the landscape.

Drawing inspiration from inherited territories (both natural and built), its projects seek to establish a dialogue with existing structures through precise volumes and the use of materials linked to the land, techniques, and building culture, contributing to a situated identity.

The studio develops diverse housing and public facilities, approaching them with a specific focus on use, materiality, and the relationship between architecture and landscape.
