The five-foot wide Keret House was built in an alley in Warsaw, Poland. Working within such tight boundaries, architect Jakub Szczesny was forced to get creative with the design. The bedroom is accessed by ladder and the fridge has just enough room to fit two drinks. While the design might be too sparse for a full-time home, Szczensny’s intent was to create a temporary home for a rotating roster of artist tenants and to push the boundaries of small space living.
