A one-story sustainable house with a square floor plan of approximately 12 meters by 12 meters. The house features a central interior garden that visually and spatially connects all rooms, promoting natural light and ventilation. The architectural style is a blend of rationalist minimalism and Asian-Thai influences, characterized by clean lines, functional spaces, and a strong connection with nature. The exterior is thoughtfully designed for year-round comfort in both cold winters and hot, humid summers. Walls are insulated for thermal efficiency, and the roof features extended overhangs that provide shade in summer while allowing low winter sunlight to enter. A mix of dark wood and corrugated metal panels balances durability and aesthetics, while the use of operable louvered panels offers adjustable ventilation and privacy. The glass surfaces are strategically placed to maximize interior light without compromising privacy, incorporating frosted or shaded glass in key areas. Perimeter galleries surround the house, providing sheltered outdoor spaces to enjoy in any season. The flat roof includes a usable terrace accessible via a discreet staircase, designed to be shaded or greened for additional insulation and comfort. The single-story height of approximately 3 meters ensures spacious interiors while maintaining a human scale. The house integrates sustainable materials, passive heating and cooling strategies, and low-maintenance landscaping. It emphasizes harmony, simplicity, and adaptability to varying climates, creating a serene and practical living environment.
