Jason de Caires Taylor’s underwater sculpture garden in Cancun. Constructed out of concrete and steel, and bolted to the ocean substrate, the works here act as artificial reefs that provide “an ideal habitat for filter feeding organisms.” http://www.dedeceblog.com/2010/10/13/cancun/
"Located in the forest, close to Ubud, Bali-Indonesia, is the breathtaking Panchoran Retreat. It is inspired by nature, creating environments it is difficult to distinguish the interior from exterior. Only recycled or sustainable materials were used to create this haven. This private hideaway has 6 houses scattered amongst nature with magical views of the valley and bamboo forest."
