Hong Kong Prefabricated Housing
Hong Kong has relatively rich experience in prefabricated housing, including private residential projects and Simple Public Housing projects, etc.
Private Residential Project Practices
The residential project at 16 - 20 Temple Street, Yau Ma Tei, Hong Kong, is the first private residential project in Hong Kong to apply fully assembled components at residential floors. This project faced numerous challenges. The site area was only 209.4 square meters, with a minimum distance of just 0.9 meters from the adjacent building. It was also adjacent to the 161-year-old Tin Hau Temple, surrounded by a dense concentration of merchants and hawkers. To address these difficulties, the project team broke down the project into 143 independent modules. These modules underwent structural, decoration, and electromechanical integration prefabrication at a smart factory in the Greater Bay Area and were then transported to the site for piece-by-piece hoisting and assembly. Regarding module connections, the project team conducted hundreds of precise calculations and half a year of repeated testing, developing the "corrugated steel pipe vertical rebar connection" process. This process has yielded remarkable results, controlling module installation errors within 4 millimeters and significantly improving construction accuracy. At the same time, it has achieved a construction speed of "one floor every three days," greatly shortening the project duration and demonstrating the advantages of prefabricated housing in enhancing construction efficiency and quality.
Simple Public Housing Project Planning
Hong Kong has proposed the construction of 30,000 Simple Public Housing units. These public housing units are essentially detachable modular houses. Their construction makes full use of short-term government idle land. When the land lease expires, the houses can be dismantled and reused, effectively improving the utilization rate of land resources and avoiding waste. Moreover, a total of 30,000 "Simple Public Housing" units will be completed and meet standards ahead of schedule by March 2027, indicating that Hong Kong has clear goals and efficient execution in promoting the construction of prefabricated housing. The construction of Simple Public Housing not only provides more options for people with housing needs but also demonstrates the flexibility and feasibility of prefabricated housing in addressing housing shortages.
