The humid forest of Brazil’s Costa Verde is the setting for this unusual small house. Nicknamed “Arca” (“Ark”) by the locals for its resemblance to an overturned vessel, the arched house was built as a getaway by architect Marko Brajovic. He designed it as a place where small groups could go to relax or to work while inspired by nature.
Wanting to minimize site disturbance, the architect started with a prefabricated metal building typically used for storage or industrial purposes. This particular building was designed to be assembled by hand, and it took only a week to complete the shell on the concrete pier foundation.
As the shell is entirely self-supporting, there are no support columns to impose constraints on the interior layout. In addition, since the end walls are non-structural, the architect could fully glaze both ends with a grid of aluminum-framed windows and sliding doors.
