The project involves the construction of a new public sports facility for the town of Cormeilles-en-Parisis on a rectangular site measuring 150 × 40 m. The building is spread over two levels (ground floor and lower ground floor) and comprises two sports halls, combat sports rooms, areas for administration and toilet facilities.
At the centre of the building, a two-storey structure, comprising reinforced concrete walls and slabs, houses the combat halls, changing rooms, toilet facilities and administrative areas. The structural stability of the north and south façades is provided by concrete walls, whilst a series of vertical timber columns runs along the east and west façades.
The roofs of the two main halls are constructed from steel troughs; the roof of the central area is a composite floor structure designed to support the technical equipment installed on the roof. The roofs of the two halls, with a span of approximately 27 m, are supported by GluLam timber beams of varying cross-sections, which create the roof pitch. In the central area, a composite system of steel beams supports the composite floor. An 80-metre-long three-dimensional canopy, constructed from a steel framework, runs along the façade.
