The Hong Kong Observatory's Tai Po Kau Tidal Gauge Station, situated on the Tai Po waterfront, is inspired by the form of a sailboat and is both functional and artistic in design. The building utilizes ETFE (Ethylene Tetrafluoroethylene Copolymer) material for the windows, which is both light-transmitting and weather-resistant. The station is equipped with tide sensors, temperature sensors, solar panels and rain gauges, integrated steel walls and adjustable floors to ensure accurate data collection. The station is a towering cylindrical structure with a metal mesh safety fence and spiral ladder to enhance practicality. The design also incorporates sculptural elements, which, when combined with the seaside setting, makes it a unique stopping point for visitors to appreciate the beauty of its elegant lines and integration with nature.
