In Indonesia’s coral-rich Anambas archipelago, about 90 minutes by seaplane northeast of Singapore, lies this five-island sanctuary built with only natural and recycled materials. Bamboo, of course, features heavily, both as a structural building material and in design elements such as latticework screens in overwater bungalows, beachfront villas and safari-tented suites.

There are other natural materials here, too. Bathtubs and washbasins were made from recycled copper, while the water heating system throughout the resort relies on solar energy. And the environmental vision goes further, with a vast permaculture garden and dishes at Tree Top restaurant made entirely from locally sourced ingredients according to a strict zero-pesticide, zero-fishing and zero-waste programme.

It’s all designed to ensure this divers’ paradise – home to turtles, octopuses and blacktip reef sharks – remains blissfully unspoilt. bawahreserve.com
