I never thought it would actually come to be. Last year I wrote about Jakub Szczęsny's design for a 3-footwide house in Warsaw, Poland.
Don't get me wrong, I love the idea of living in small spaces. I write about them all the time. But the Keret House is 122 cm (48.031") at its widest, 72 (28.34") at its narrowest. I know people wider than that.
Check out a video of the narrow home below.
