Open-air market is the most common and simplest form of street business in the country. With the expansion of Bangkok suburb following the relocation of Bangkok airport 6 years ago, the market transforms the physicality of temporary market into a proper open-air market serving the new suburb middle-class. The building accommodates several local-global commercial activities from street venders, food & goods stalls, food courts to a franchise minimart - a mixture of the city's economy. The roof structure borrows and twists the local tent typology, which is the conventional temporary structure. Although the building is concretely established in its form, it allows the fluctuation of events, encourages the plasticity of space which is, perhaps, its genius loci.
