The hotel towers slope but stand on straight legs, which give the complex its unique look. Tower 1, in particular, has a slope of 26 degrees. The architecture also follows the principles of feng shui to create a perfect balance of energy and harmonisation with the environment. It is interesting to note that the number 26 – the slope of Tower 1 – is considered prosperous since the individual digits add up to 8, a lucky number in Chinese culture.
The three towers stand as individual modules, but are unified at Level 23, and again at the top of the towers by the SkyPark cantilever sitting 200 meters above the city. If that sounds awesome, then consider the area of the SkyPark – its length exceeds the height of the Eiffel Tower!
The SkyPark measures 1.2 hectares (12,000 square meters), which is enough to fit more than four A380 planes. But the space is probably better served for the restaurants, cafés, 250 trees, 150-metre long infinity pool, and viewing decks that offer 360 degree views of Singapore’s skyline and surrounding waters.
Apart from these visible architectural qualities, the complex has a plethora of design features that are not so prominent. Because the buildings are of such height, they are prone to wind sway. In other words, strong winds from the seas off Singapore cause the towers to move. That is why there are four movement joints right under the main swimming pools, to counteract these forces. These joints move an average of almost 20 inches to keep the structure steady.
And because the buildings are of such weight, the entire complex is prone to settling into the earth over time. This could lead to some serious issues in tilting, which is why there are more than 500 jacks beneath the structure to permit adjustments when required. In other words, these systems work hard to keep the infinity pool level.
Other invisible feats of architecture are the environmental systems that use rain water for the cooling systems, and the kinetic elevators that recycle parts of their motion to conserve energy. Rain water is collected at the ArtScience Museum – an architectural marvel in itself – and is recycled throughout the complex. The resort's design allows abundant natural daylight to illuminate indoor areas, reducing the need for additional lighting.
