The new nursery building in Prangins is composed of four volumes gravitating around a central staircase flooded in natural light. The volumes, which form a cross-shaped geometry in plan view, are set at different levels according to the natural slope of the terrain.
The load-bearing structure consists of a conventional system of reinforced concrete walls and flat slabs. In order to free the courtyard from any intermediate support, the facade wall works like a deep beam suspending the slabs. Furthermore, the slabs are prestressed over the large windows to limit the deflections.
