In mid-June 2015, Calais was in a festive mood due to the new bright pavement at Place d'Armes in the historic city center of Calais, France. Therefore, three festival days were planned to inaugurate the new multi‑purpose hall in the city center.
The hall made of steel, timber and aluminum has a modular structure and thus can be used for many occasions (weekly markets, fairs, concerts, spectacles, and other events). The clear style and the windows on the north and south side allow a lot of daylight which is reflected by the internal wood cladding.
On the west side, a folding door can be opened to have an outdoor stage with 21 meters.
The multi-purpose hall in Calais is a structure with a wide self-supporting span of 20 x 37 x 12.5 m.
On a base area of 1,000 m2, the hall has a room with 750 m2.
The gathered form of the interior wooden cladding and the exterior aluminum coating fit perfectly due to rigid metal frame beams bonded to each other which adapt perfectly to the forms.
The grid metal frame beams have a static depth of 1.75 m with a span of up to 33.5 m. In order to stabilize them laterally, shell constructions of reinforced concrete were constructed and used for the engineering rooms of the building.
