As Pierre-André Comte, of local firm Comte & Vollenweider, explains, “We won the contract by challenging the logic of the competition recommendations.” In their proposal, the architects pivoted the sports hall 90° so it occupied one end of the site and replaced the lost classrooms from the demolished steel block by extending the concrete structure at either end. “In this way,” continues Comte, “we ensured as large a schoolyard as possible, while grouping all the pupils together more efficiently in a single wing.”

Built using a slab-and-post system, the existing concrete structure featured prefabricated, molded façades, which Comte & Vollenweider initially intended to replicate on the additions. When this proved impossible because of current seismic regulations, they opted to reproduce the bay width of the old building on their extensions – a 5½-foot bay is a useful unit for creating well-proportioned classrooms, says Comte – and to unify the new and old façades with a system of protruding, aluminum glazing frames, one in each bay. “We sought to blur the limits between inside and out by projecting the window frame into space,” explains Comte. Color-coded to indicate different functions (green for areas where there are standard classrooms, orange for IT classes, violet for the library, etc.), the glazing brings a strong visual identity to the institution.

Realized in a similar vocabulary, the sports hall is a minor feat of engineering, suspended above grade so that the schoolyard continues beneath it. (Covered playgrounds for rainy days are a staple at French schools.) Three aluminum-clad concrete towers – two containing stairs, the other equipment storage – carry the giant steel truss that forms the hall proper, which is crowned by a rooftop playing field in synthetic grass. Thanks to high-performance glazing developed by Saint-Gobain, the hall’s sun-exposed southern façade, facing the schoolyard, is entirely transparent.

Construction was carried out in phases, from February 2016 to December 2020 – the school remained in use throughout –, and included the architects’ remodeling of the yard, which they leveled and resurfaced in a non-heat-absorbing, sand-colored resin material, and planted with numerous new trees that will help reduce the effects of summer heat. In contrast to the shabby old school within a barren yard, Comte & Vollenweider’s transformation, all sparkling glass and aluminum in a verdant setting, is a far more auspicious incarnation of that old saying, “the children are our future.”
