The three hundred thousand Nha Trang is the capital of the Vietnamese province of Khanh Hoa. In addition to long beaches and picturesque islands scattered in the South China Sea, the city is also popular for its thermal springs and mud baths. A project by the Vietnamese studio a21studio aims to revitalize one of the springs on the rocky outskirts of Nha Trang, which sought to provide an alternative to overcrowded bathing on the beaches. The modest project named “The Tent 2” (tent) features massive roof structures set on stones. The design lacks traditional walls or facades. The rocky terrain is skillfully used to shield or open the views. At its widest point, the wooden truss spans eleven meters. The sprawling roof made of coconut palm leaves protects bathers from the harsh western sun. The interior space of 126m² is divided into two levels. The upper part contains a bedroom with a bathroom as well as a suspended trampoline. In the lower half, there are two pools with mineral water. The smaller outdoor pool with a square footprint is screened among boulders, while the larger covered triangular pool offers panoramic views of the bay. The architects intentionally chose local building methods and utilized materials from the area.
