The narrowest house in the world, 92-152 centimeters wide, is a sliver installed between two buildings in Warsaw. Over two floors, the house has one bedroom, a kitchen, a bathroom, and a living area. Light comes from two windows and the translucent glass panels that make up the slanted wall/ceiling. The installation, constructed in 2012, was designed by architect Jakub Szczesny. Keret House was named for Israeli writer and filmmaker Etgar Keret, who was the first artist to reside in the structure. Other artists have stayed for study visits and residencies up to 21 days long.
