Rirkrit Tiravanija's work Untitled (Tilted Tea House with Coffee Machine) was created in 2005 and was installed in the Bródno Sculpture Park in 2009. In 2010, the original work was returned to galerie neugerriemschneider, and a replica/copy of the work was created in the Bródno Sculpture Park; the design was modified by Paweł Althamer in consultation with Rirkrit Tiravanija. The modifications included, among others: lockable doors, windows that open upwards, additional steps.
