With the same modular constructive system that was used in the first libyan work in city of Misurata, we designed this multi-purpose sports center. The idea is very similar but in this case it is a closed, air-conditioned building. In order to achieve cover the stands and the pitch, we made a dome by lattice arches that meet at a central compression ring. All protected by a lightweight aluminum housing, heat insulated to ensure the comfort of the public. Aesthetically it is very similar to the stage of Misurata, only with a more pronounced volume.
