Another fascinating version of trees on houses rather than houses on trees would be the Park Royal in Singapor by WOHA.
The architects statement:
“Designed as a hotel and office in a garden, the project at Upper Pickering Street is a study of how we can not only conserve our greenery in a built-up high-rise city centre but multiply it in a manner that is architecturally striking, integrated and sustainable. Located in central Singapore, the site is at a junction between the CBD and the colorful districts of Chinatown and Clarke Quay, and faces Hong Lim Park. A contoured podium responds to the street scale and is sculpted to form dramatic outdoor plazas, gardens and terraces which flow seamlessly into the interiors. Greenery from the park is drawn up the building in the form of lushly planted openings, crevasses, gullies and waterfalls, which also conceal above ground carparking, thus creating an attractive urban element.”
