Mexico City architects at Senosiain Arquitectos designed this house that is in the shape of a Nautilus. This bizarre example of Green Hot was commissioned by a couple who now live in the house along with their two small children. The house is as much a sculpture as it is an abode. Built using fibrocement construction, a technique involving a frame of steel-reinforced chicken wire with a special two-inch-thick composite of concrete spread over it, the house is earthquake-proof and maintenance-free. Natural forms, smooth surfaces are present throughout the interior giving the interior an organic yet unearthly theme. Aesthetically unique and structurally superior in many aspects, the house is a wonderful fusion of art and engineering.
