Castaway Island Resort is located on a beautiful tiny island in Cat Ba Archipelago, a well-known tourist destination in Vietnam. The site is only accessible by boat, which takes about two hours from Hai Phong port. The resort has room for up to 160 guests.

On a private beach, engulfed on one side by a beautiful mountain range and on the other by an expansive shore of white sand, the resort consists of five huts, a restaurant, and a pavilion. The seven volumes are built using thin canes of bamboo (Tam Vong), measuring barely 50 millimeters in diameter, assembled by bamboo dowel nail and then tightened by rope. Despite using the same material, the constructions present different geometries. The restaurant features a hyperbolic-parabolic shell structure, which forms a semi-outdoor space for social gathering and interaction. Each of the thirteen bamboo shell units is composed of 80 bamboo elements, creating a wavy ceiling and rhythmical roof landscape. The five pointed huts are built with prefabricated frames that are assembled on the site, speeding up the construction process. Lastly, the pergola of the pavilion rests on ribbed bamboo umbrellas that support the thatched roofs.
