Often referred to as the skinniest house in the world, the Keret House is nestled into a narrow space between two structures in Warsaw, Poland. The unusual structure was designed by Polish architect Jakub Szczesny of Centrala as an art installation and functional living space. At its narrowest point, the structure measures just 72 centimetres (28 inches) wide, expanding to 122 centimetres (48 inches) at its widest. It occupies roughly 150 square feet of previously unused space between a postwar housing cooperative and a prewar former Jewish tenement building.
Indian influencer Rishabh Wadhwa recently visited the house and shared a walkthrough of the tiny interior. He highlighted how the space-saving design allows several functions to fit into the extremely narrow structure. The entrance is not directly accessible from the main street. Visitors have to acess it through an alley, where steel stairs lead into the building. The main entrance is also concealed from the sidewalk by a wall roughly 6½ feet high. Despite its tiny footprint, the house includes a shower, toilet, mirror, storage and work areas. A skylight running across the ceiling brings natural light into the otherwise tightly enclosed space. Lighting has also been incorporated into the structural framework, turning functional elements of the house into part of its minimalist aesthetic. The idea came to Szczesny while he was walking along the street and noticed the unusually narrow gap between the two buildings. He envisioned using the space to create a functional structure that would effectively connect them.
