Keret House in Warsaw, Poland
Wow! This is the "Keret House" and is considered the narrowest house in the world!! It is named after Israeli writer and filmmaker Etgar Keret, who was the house's first tenant and is located in Warsaw, Poland. The house is sandwiched between a pre-World War 2 house and a newer apartment building. Although this house represents a way to combat increasing population and house prices, Keret considered it a "memorial to his family" since his parents' families died during World War 2 when Nazi Germany occupied Poland.
