A 1960s-inspired window wall fronts this extension to a psychiatric institute in Paris by Local firm Atelier 2+1 (+ slideshow).

Atelier 2+1 was asked to restructure the headquarters of the Paul Sivadon Institut in Paris's 9th arrondissement, and to create a 2,300-square-metre extension housing a dining hall.

The institute comprised a building from the Haussmann era facing the street, and a perpendicular 1960s addition flanking one side of a dingy central space that was being used for parking.
The stylings of these building provided the starting point for the new design.

"The project's objective was to rehabilitate the courtyard, the core of the establishment, while creating a public square, linking the patient space to the township," the architects told Dezeen. "Our aim was to create a reassuring cocoon for the patient."

Planning regulations permitted any alterations to the existing structures, so the project team focused on the introduction of an extension that lines the rear of the new courtyard.
A vaulted porch in the Haussmann building leads from the street into the bright central space, which is now surrounded by glazing.

The two-storey extension contains the restaurant on its ground floor, with doors opening onto the patio to encourage patients to spend time there.
