Sharma Springs, Green Village, Bali. Ibuku, 2012 From above, this building looks like dry petals on a bed of moss. It is in fact a six-storey forest home made entirely of bamboo. Each lanceolate leaf is a roof covering an open wing of the house; the thick grey stalk is a tunnel that crosses a green ravine and leads to the building’s fourth floor. Photograph © Errol Vaes
