Nautilus House, located near Mexico City, Mexico, is a whimsical shell-shaped house that is an extraordinary example of 'bio- architecture'. The house was designed by Javier Senosiain of Arquitectura Organica, and inspired by the work of Gaudi and Frank Lloyd Wright.

The house was named after the shells of the nautilus cephalopod, the logarithmic spiral of which the building mimics with its curved concave shapes.

The structure was created using ferro-cement and consists of a frame of steel-enforced small-diameter chicken wire which is coated with a thin layer of concrete. This material weighs less than brick and is earthquake resistant.

The technique allows rounded natural curves to be formed, which avoids the necessity of bearing walls or columns. It offers continuity between the ground plane, walls and roof, creating the impression of the building emerging organically from the ground.

The house is illuminated with natural light from above as well as from the external wall which is lined with hundreds of small rainbow-coloured stained glass windows.
