At peak flow, the new regional airport at Limbang can handle three planes and 180 passengers (half of them arriving, the others departing). Its main concourse has a high ceiling, for improved ventilation, and a mezzanine level with a viewing gallery overlooking the parking apron and runway. The dynamic roof form expresses the idea of a 'gateway' - the airport is a point of entry to the northern region of Malaysia. The metal roof is double-insulated and rests on steel trusses supported by concrete columns and beams. Extended roof eaves provide protection against weathering. Below them, the airside facade has full-height glazing.
