The Bat House is a spatial installation that serves as a habitat for bats. The architectural frame of the object follows a traditional modernist structure but uses reflective materials on its surface, making it almost invisible to the naked eye. The Bat House actually displays a simulacrum of a functional form. The sculpture was initially placed in Walthamstow Marsh, a wildlife reserve close to the London 2012 Olympic site, and was later photographed as a monument against the winter sky. The invisibility of the habitat for these shy animals is there for a purpose: it challenges instability of vision as the surrounding natural and man-made landscape is reflected and obscured.
