Keret House in Warsaw: Just 72 Centimetres at Its Narrowest
The essentials: Keret House in Warsaw is a 14-square-metre house squeezed between two buildings at the corner of Zelazna and Chlodna streets in Wola. Opened on 20 October 2012, it measures 122 cm at its widest and 72 cm at its narrowest - dimensions that lead the Adam Mickiewicz Institute to call it the narrowest house in the world.

Between a pre-war tenement at Chlodna 22 and a 1970s block at Zelazna 74, in the Wola district, a slim wedge of white metal fills the gap: Keret House, described by the Adam Mickiewicz Institute culture.pl as the narrowest house in the world.

The house has about 14 square metres of floor area. It measures 122 cm at its widest point and just 72 cm at its narrowest - the dimensions behind the superlative. Inside there is a microscopic bedroom, kitchen, bathroom and work space, reached by a pull-down stair.
