When construction began in 2008, Palais Royale was expected to be the India’s first super tall building. The location in the Worli area of Mumbi was traditionally a low-rise neighborhood, but like much of the city at large, has been experiencing a high-rise building boom and a rapidly emerging skyline. The luxury building was the first residential tower was the first to designed around a LEED pre-certification and from the onset of the project, the development team sought to achieve a platinum rating.

In order increase the comfort level of the occupants, the tower was designed to have as little movement as possible through the use of very robust reinforced concrete frame and a low aspect ratio of 1:3. With a wide tower footprint of 100 meters across, the structure was able to incorporate an interior atrium stretching 215 meters in height, among the tallest atriums ever constructed. Because the tower design did not have a podium or any adjoining structures, parking and amenity levels were included within the tower footprint. This required a wider spacing of columns in the lower floors and the use of an extensive load transfer, in which the reinforced concrete beams are up to 9 meters deep, among the largest ever constructed. Construction also broke a record for the largest single day concrete pour in the history of Mumbi.

The design specifies the façade cladding to be entirely made of DuPont’s Corian, the first time it has been used on a residential high-rise and was chosen for the material’s resistance to the local humid tropical climate. With the rapid growth of Mumbai, the development team included many green features working to reduce the building’s impact on the city’s often overburdened infrastructure. This includes an on-site sewage treatment plant, organic waste composting, rainwater harvesting as well as wind turbines and solar panels, all of which contribute to the ambitious design’s approach towards sustainability.
