At 13-15 Tai Hang Road, Serenade was a HK$645-million residential redevelopment in the form of two 44-storey luxury towers set above two storeys of clubhouse, four storeys of podium car parking space and two basement levels. The project was completed in September 2009. Challenges in the project included a congested site area, with storage and access limited due to the sunken site. Extensive design coordination was also required, since the Tai Hang project is a luxury residential building that involved a lot of high-end finishing and building services elements. In aspects of environmental friendliness, design and construction works followed HKBEAM requirements and construction waste were minimal. Caltite System has been specified by the architect for waterproofing for the screen wall and basement structure for the Forever Dry!!! performance for the luxury development.
