The theme of circling, flowing movement runs through every project by Grupo Aranea. Based in the coastal city of Alicante in southeastern Spain, the studio is led by architect Francisco Leiva Ivorra and his wife, landscape architect Marta García Chico, who draw inspiration from curving natural forms. Their first building, a library in San Vicente del Raspeig completed in 2004, is a continuous spiraling ramp. And both a seaside spa in Gijón and an Environmental Observatory in Alicante spin around themselves in open-ended loops. Their Lude House sits like a hard white seashell atop an existing building in the town of Cehegín, rippled inside and out by the curving, rising movement of its stair and double-height living area.

Even a completely orthogonal design, a public high school in the village of Rafal, is organized around circular movement: a pink-carpeted bleacher opposite the entrance, which doubles as a wide stair and meeting point, kicks off a sequence of corridors and outdoor spaces that circle back over the entry and around a playing field to connect classroom pavilions.
