Setting lush flora against stratified concrete, the exterior of Parkroyal on Pickering looks like the Hanging Gardens of Babylon. Inside, however, the hotel is all about the now. An organic palette draws influence from nearby Hong Lim Park, while textured surfaces hide doors and openings, giving rooms a slick, streamlined look. Eco smarts are another strong suit. From the use of recycled materials to filtering its bottled water, the hotel is proof that good design can be good for the planet, too.
