We present in this paper the construction of a low-cost edible-nest swiftlet master house, the settlement of swiftlets, nesting, nest production, costs and the payback period. Data was collected from April 2010 to April 2016. The master house was constructed as a single-story building, 5m wide x 13.5m long x 4m high. Edible-nest swiftlets (Aerodramus fuciphaga), were attracted to live in the master house and build nests. The nests were attached to a plank and construction takes four to five weeks. The female bird of a pair usually lays a clutch of two eggs, which are brooded co-operatively by the pair. After hatching, the young swiftlets are reared by the parent until they are able to fly in five to six weeks. The average weight of the nests was 7.77 ± 0.48g. The air temperature and relative humidity in the master house averaged 28.27 ± 0.01°C and 82.56 ± 0.03% respectively. The specific growth rate of the bird’s nest population was 8.9 % per month. The return on investment was calculated for average prices per kilogram of USD893 and USD596, for which the payback period was 3.3 and 5.7 years, respectively.
