Bioarchitek was commissioned by the Sports Authority of Thailand for the Indoor Futsal Stadium which is a special renovation project located in Huamark, Bangkok. The main challenges were to expand the playing area, and renovate the roof and façade while maintaining the features that are essential to the character of the building. The stadium was built in the 1950’s, and no construction drawings remain. It was our responsibility to investigate the integrity of the building and renovate the leaking roof without changing the appearance of its traditional folding structure.
