Wedged into the narrow space between two buildings in Warsaw, Poland, the Keret House is considered the narrowest home in the world. At just 36 inches across at its narrowest point and 48 inches at its widest, the house is barely large enough for one person to move around.
The unique living space is the brainchild of Israeli writer and film maker Etgar Keret. The gap between the two buildings was discovered almost six years ago, by Polish architect Jakub Szczęsny. He realized that it was just enough room to fit a house, so he decided to go ahead and build one. Coming up with a design for the tiny available space was tough, but the real challenges were ownership issues, building regulations and financing. Luckily, he managed to raise 70,000 euros (over $80,000) for the project and began the construction in collaboration with the Polish Art Foundation.
