Salar de Uyuni (or Salar de Tunupa) is the world's largest salt flat at 10,582 square kilometers (4,086 sq mi). It is located in the Potosí and Oruro departments in southwest Bolivia, near the crest of the Andes, and is elevated 3,656 meters (11,995 ft) above mean sea level. The Salar was formed as a result of transformations between several prehistoric lakes. It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar.

British designer Alex Chinneck created the installation - called From the Knees of my Nose to the Belly of my Toes - by removing the facade of a detached four-storey house that had been derelict for eleven years and replacing it with a brand new frontage that leaves the crumbling top storey exposed, then curves outwards so the bottom section lies flat in front of the house.
