Oasis Hotel Singapore

Oasis Hotel Singapore is a lush green tower in the dense central business district, a prototype for tropical urban land intensification. Unlike the smooth, sealed skyscrapers that have evolved in warm western climates, this tropical vitality tower offers an alternative image for the genre's fashionable technology. To distinguish office, hotel, and club functions, WOHA created a series of staggered spaces, each with its own sky garden. These additional ground levels create more public recreation and social interaction opportunities within the high-density CBD. Viewed from surrounding towers, the Oasis carves out its own interior spaces and dynamic vistas rather than relying solely on exterior visuals. Each sky garden functions as an urban viewing balcony; through designed gardens at height, the building achieves open form and visual transparency. This openness also allows breezes to cross-ventilate the building. In tropical spaces filled with greenery, natural light, and fresh air, public areas become more functional and comfortable rather than closed, air-conditioned interiors. Landscaping is extensively used as the building facade treatment, forming a major material panel both inside and out. The green tower serves as a refuge for birds and animals, reintroducing biodiversity to the city with a total green ratio of 1,100 percent. This figure effectively compensates for the lack of greenery in approximately ten surrounding buildings. The tower's red aluminum mesh cladding is designed as a background wall for 21 varieties of climbing plants, with colorful flowers interspersed among green leaves to provide food for birds and insects. Vines are arranged in mosaic patterns so each type receives optimal light, shade, and ventilation. The tower roof is not flat but a tropical pavilion filled with flowers, diversity, comfort, and vitality.
