Facing a heterogeneous hospital estate—the main building, constructed in 1978, is no longer entirely suited to modern medical practices—the Centre Hospitalier Simone Veil in Blois is embarking on a major reconstruction guided by an ambitious and responsible vision.

The project is based on a radical choice: grouping all extensions into a single building instead of fragmenting the construction. This approach makes it possible to maintain hospital activity without interruption, gain 6 years on the initial schedule, and halve the duration of the works.

By delivering all accommodations, as well as the operating theater, in a single block, the project secures strategic functions while radically reducing the risks of hospital-acquired infections (nosocomial) and aspergillosis.

The environmental approach is at the core of the project. Rather than demolishing the main building to rebuild anew, the architecture preserves and refurbishes the existing structure.

The characteristic curved concrete panels, designed by architect Jean Seac’h, are retained thanks to high-performance interior insulation. The new facades use stone from French quarries and site concrete based on local earth, drastically reducing the carbon footprint.

To anticipate unpredictable changes in medicine over several decades, the project proposes neutral and modular architecture based on a 7.50 m orthogonal grid. The large, continuous horizontal floor plates, regularly punctuated by 15 m patios, ensure natural light and maximum flexibility. This organization allows for all future reconfigurations, both during the design phases and throughout the life of the building.

The project also aims to reintegrate the hospital into the urban fabric by extending the Mail Pierre Charlot, a structuring green artery of Blois, right to the heart of the hospital site. The plane tree alignments redefine a coherent built front and provide a strong vegetal identity. The new double-height lobbies, finished with tufa and slate terrazzo, open onto planted patios, creating a soothing atmosphere where wood and nature mingle.

The architecture decidedly places well-being at the center: generously glazed facades offer light and panoramic views, wooden loggias at the heart of each unit create genuine “village squares,” and bright breaches form breathing spaces within the departments. The modular “T” organization optimizes professional pathways, reducing the distances to be covered between the furthest rooms by up to 40%.

Ultimately, this project embodies a vision for the future that reconciles operational efficiency and quality of use: a compact hospital respectful of its architectural heritage, frugal in its means but generous in its spaces—a place that truly cares for its users and contributes to patient recovery through the quality of its architecture.
