Seperating functions
Expected kick drum peaks from the nightclub are in the bass band region where conventional building acoustics is deficient. To preserve the hotel guests their good night sleep, the hotel is therefore decoupled from the nightclub. By separating the different functions flanking transmission is reduced dramatically. Two load-bearing systems are created; the facade carries the offices and nightclub by a complex tree structure, while the hotel is carried by the elevator cores. Since the offices don’t operate at the same hours as the nightclub, it is used to add stiffness to the facade tree.
Nature suffers from urban areas expanding at a far greater speed than ever before. The Tree aims to reclaim some of the urban space by abstracting itself to blend in with the idiom of the city. Rooting in the ground plaza, it gathers nourishment and energy from water before it majestically rises to the sky. A complex branch structure carries the simple cuboid that holds the functions of a typical urban skyscraper. Travelling upwards, the experience becomes more and more appealing as the tree structure encounters the human scale. The grammar of a tree inspires everything from the load bearing system to the finest interior detail. By planting The Tree in Hong Kong, nature will at last get its revenge.
Reducing vibrations
The low frequency vibrations from the nightclub are transmitted through the facade tree structure. Due to impedance mismatch at each branch junction and material damping treatment on the load bearing structure, a natural attenuation provides sufficient vibration isolation at the hotel facade.
HVAC
Absorbing and isolating sound
Wood is loved due to its complex anisotropic structure and variety of uses. It has great acoustical features and is easy to work with, making it possible to accomplish predetermined design objectives. Wood is in a large extent used in The Tree design, e.g. irregular shaped wall diffusors, absorbing slatted wood panel and wood ceiling reflectors. Combined with heavier materials it is also used for isolation purposes.

Refining the site
Situated in the very dense and somewhat declined district of Mong Kok in Hong Kong, The Tree certainly stands out from the surroundings. Amongst the damp and shady roots of the tree, one will find a welcoming shelter from sun and traffic. This area is built much like a plaza, encouraging people of the city to pass through as well as serving as an embracing entrance for visitors To create a convenient public space with low annoyance, three simple principles are applied:
