"Located in the coastal suburb of Chachoengsao, east of Bangkok, Thailand, Villa Backyard is a 90-square-meter single-family residence designed by TOUCH Architect and completed in 2021. The project was built on a site with an artificial pond, surrounded by an environment affected by excessive soil salinity from the nearby Gulf of Thailand. The design responds directly to these challenging site conditions with a dramatically sloping roof that channels fresh rainwater into the pond to help dilute the brackish water. The house originated from a simple cube that was diagonally sliced in half, resulting in a wedge-like volume. The steeply sloped, cantilevered roof and wall not only drain water but also shade the interior. Large glazing allows the interior to open up to views of the water, with the level of openness adjusted to the functions within. The highest level of openness is at the entrance terrace, while middle and low-level openings allow for panoramic views from the living space and bedroom, respectively, whether sitting or reclining. This creates a ""hierarchical openness"" that celebrates the water's edge. The cantilevered outdoor terrace features a steel grating floor, which allows rainwater to fall directly into the pond below and helps cool the air through water evaporation. Aluminum trellis panels are used on other walls for heat protection. The interior features an open-plan living space designed for multipurpose use. The simple and functional design accommodates various activities like family gatherings and dining, and can also serve as an extended sleeping area. The house utilizes a lightweight steel structure with an asphalt shingle roof, facilitating quick construction.
