Keret House in Warsaw, Poland

If you look closely at the small crack between the two structures in the photo above, you’ll notice the Keret House – the world’s thinnest house.

This project has garnered a ton of attention for years as nothing more than a concept, but designer Jackub Szczesny of the Warsaw-based studio Centrala has brought this thing to life. The residence was named after Israeli writer and filmmaker Etgar Keret, and measures in under 5 feet at its widest point. In fact the home is so thin, it has to be deemed an art installation under Polish law. The tiny home spans 44 square feet, and comes complete with a kitchen, bedroom and bathroom. So while it might be a micro home, it packs everything needs to live comfortably.
