Château of the Hertford British Hospital Rehabilitation: Adaptive Reuse by Maud Caubet Architectes

In Levallois-Perret, Greater Paris, the Château of the Hertford British Hospital rehabilitation by Maud Caubet Architectes breathes new life into a Neo-Gothic landmark. Built between 1877 and 1879 by Paul Ernest Sanson, the château once served British patients, with its maternity ward operating until the late 20th century. Now, under the guidance of Maud Caubet Architectes, this historical site has been thoughtfully reimagined into a vibrant and accessible space for contemporary use.

Preserving Heritage Through Adaptive Reuse

The rehabilitation is rooted in adaptive reuse architecture, balancing preservation with innovation. Extensive historical research, including archival documents, original drawings, and photographic studies, guided the restoration process. Rather than creating a replica of the past, the project highlights key heritage elements while adapting them to modern functionality. The stone and brick façades were carefully restored, PVC windows replaced with historically faithful designs, and the 1879 entrance door reinstated to its original form.

Contemporary Transformation of Interiors

Inside the château, the interiors have undergone a complete reconfiguration. New staircases, a modernized elevator, and discreet accessibility features ensure universal use while preserving historic proportions. Previously unused attic areas are now transformed into dynamic workspaces, offering light-filled, vaulted rooms that celebrate the building’s architectural richness. Ribbed vaults, arches, and moldings are meticulously revealed, honoring the original craftsmanship while meeting the demands of modern work environments.

Sustainability and Energy Performance

Sustainability plays a central role in the rehabilitation. Thermal insulation is introduced internally to protect the façades, while structures are selectively reinforced to ensure long-term stability. Materials are sourced from bio-based and geo-based industries, aligning with ecological responsibility. The château is designed to achieve high energy performance while respecting the integrity of the historic building.

Reinterpreting the Historic Garden

Landscape designer Lynda Harris reimagines the château’s historic English-style garden. Mature trees are preserved, new drought-resistant plantings introduced, and pathways redesigned using permeable materials. Technical service zones are transformed into fully greened areas, creating a peaceful and vibrant environment that enhances the architectural restoration. The garden now offers both tranquility and fluid movement, reconnecting the site with its urban surroundings.

Integration into a Larger Urban Vision

The château’s rehabilitation is part of a broader urban redevelopment of the Hertford British Charitable Fund site. Adjacent office buildings have been harmonized with new façades, and the former maternity ward is converted into residential housing with continuous balconies. This integration ensures that the project not only preserves heritage but also enriches community life, blending historical architecture with modern urban living.

The Château of the Hertford British Hospital rehabilitation by Maud Caubet Architectes is a model of adaptive reuse that respects heritage while embracing contemporary needs. By restoring the château’s architectural identity and reimagining it as a place for work, learning, and community, the project demonstrates how architecture can bridge history and modernity in a sustainable and inspiring way.
