A verdant tower of green in the heart of Singapore’s dense Central Business District (CBD), Oasia Hotel Downtown is a prototype of land use intensification for the urban tropics. This tropical “living tower” offers an alternative image to the sleek technology of the genre. WOHA created a series of different strata of offices, hotel and club rooms, each with its own sky garden. These additional “ground” levels allow generous public areas for recreation and social interaction throughout the high-rise, despite the inner city high-density location.
