Warsaw's Most Improbable Address
Tucked into a gap between two Warsaw buildings so thin that the city refused to classify it as a conventional dwelling, the Keret House has become one of Poland's most photographed architectural curiosities. At its narrowest point the structure measures just 72 centimetres across, widening to 122 centimetres at its broadest. That is less than the width of a standard door.
The project was first reported by The Economic Times, drawing on earlier coverage by Houzz magazine and a walkthrough video posted by Indian influencer Rishabh Wadhwa.
How a Gap Became a Home
Polish architect Jakub Szczesny of the practice Centrala conceived the idea after noticing the unused sliver of space while walking down a Warsaw street. He envisioned connecting the two flanking buildings, a postwar housing cooperative on one side and a prewar former Jewish tenement on the other, with a structure that was genuinely habitable rather than merely decorative.
The house was built for Israeli writer Etgar Keret, who uses it as both a workspace and an occasional residence. Construction took roughly three years, completing in October 2012. Warsaw's building authorities presented an early obstacle: the structure's unconventional dimensions and location meant it could not be permitted as a standard building. The city ultimately classified it as an art installation, which allowed the project to proceed.
Three Levels, Every Centimetre Counted
Despite occupying approximately 150 square feet in total, the interior manages to accommodate a surprising range of functions across three distinct levels. The ground floor serves as the entrance. One level up, a kitchenette, seating area, bathroom and workspace share the available width. A ladder connects that floor to the uppermost level, where the sleeping area sits.
Natural light enters through a skylight that runs the full length of the ceiling, preventing the interior from feeling entirely cave-like. Lighting has been integrated directly into the structural frame, keeping fixtures from consuming any of the precious floor space. Storage, a shower, a toilet and a mirror are all present, each fitted into whatever geometry remained.
Access is deliberately indirect. Visitors do not approach from the main pavement; instead, a side alley leads to steel stairs that climb into the building. The entrance itself sits behind a wall roughly two metres tall, hidden from the street.
Why It Matters for Hosts
Independent accommodation operators in Warsaw can draw a practical lesson from the Keret House's enduring appeal: constraints, framed honestly and creatively, become selling points rather than apologies. Guests increasingly seek experiences that feel specific to a place. A compact room, an unusual footprint, or a building with a layered history can be positioned as part of the story rather than a limitation to manage. Consider whether your property has an architectural or historical detail that deserves its own explanation in your guest communications, rather than being left for visitors to discover or, worse, misinterpret.
