Structure in general
- Highcliff has a passive wind-damper on top.
- With the developer's brief of setting a target size of 3,000 square feet per residential unit, the architects embarked on this now characteristically narrow and single tower design.
- The design allows for 2 units per floor on what was described as a very tight building site.
- Because of the height of the building and future maintenance concerns, screw-on metal cladding and glass curtain walling has been used in this project.
- While building damper systems have been applied to minimise building movements in Japan, they are typically computer controlled - at Highcliff, the project team decided on a passive and maintenance-free system.
- The damper system is the first of its kind for a residential building anywhere in the world.
- Experiments have shown that the damper system is capable of reducing movements from eight seconds each to just 4.7 seconds, making for a significant difference in residents’ comfort - by the time someone notices any movement it has stopped.
- The inclusion of such a damper system is mainly due to typhoons that plague the region -usually in the late summer and where winds can gust up to 100 mph not to mention sudden changes in wind direction as well as wind shear.
- Elevators to the residential units do not feature a typical high-zone/low-zone configuration as the project team felt it was unnecessary in this setting.
- In this design, there is purposely no readily identifiable rear to the tower which makes a difference to residents living in the other adjacent buildings - located as they are in one of Hong Kong's premier high-income districts.
