Keret House, Postmodern building in Wola district, Warsaw, Poland.
Keret House is a two-story structure wedged between two existing buildings with a width ranging from about 92 centimeters to 152 centimeters at different points. Inside, the space contains basic furnishings including a small refrigerator, seating for two people, and a ladder connecting the upper and lower floors.
The site sits at the intersection of Chlodna and Zelazna streets, where two ghettos existed during World War II. The structure was built in 2003 at this historically significant location as a form of commemoration and reflection.
Polish architect Jakub Szczesny created this structure as a functioning art installation and temporary home for visiting writers. The space serves as a living artwork that invites people to think about how creative people use and inhabit spaces.
The building is accessible from the street and visitors can view the entrance and exterior, though the interior is extremely confined and requires careful movement. It's best to visit during daylight hours when natural light enters through small openings, making it easier to appreciate the space and take photographs.
This structure holds a Guinness World Record as the world's narrowest house, with a width of only 92 centimeters at its thinnest point. The extreme tightness of the space became internationally famous and draws attention to creative problem-solving in urban architecture.

Warsaw combines medieval architecture with modern districts and offers visitors a look at several centuries of Polish history. The Old Town was reconstructed after World War II and includes the Market Square, the Royal Castle and the Barbican. The Palace of Culture has defined the skyline since the 1950s, while Wilanów outside the center displays baroque grandeur. The city stretches along the Vistula River, whose banks provide space for walking. Łazienki Park combines gardens with neoclassical buildings, while the Saxon Garden counts among Poland's oldest public parks. The POLIN Museum documents the history of Polish Jews, and the Neon Museum preserves postwar commercial signs. Praga on the right bank of the Vistula retains prewar buildings and has become an emerging arts district. Zabkowska Street shows preserved 19th-century tenements. Scientific institutions like the Copernicus Center and cultural venues complement the historical sites.
