If you ever thought your house isn't big enough, think again. This house, designed by Centrala, is probably the thinnest house ever made. At it's widest point the construction will be just 4 feet and 28, 3 inches at it's thinnest. If you want to see it for yourself, you'll have to go to Wola in Poland. Ow and wait a year before you go, since construction will start in September.
