Estonia-based firm Kodasema creates creative tiny Koda house. This thing is essentially a nice big concrete box with one side made primarily from glass. That isn’t to put this down at all – much of the appeal of the home comes from its simplistic design. Taking just seven hours to build, this minimalist 326 square foot concrete home contains a full bathroom, laundry room, and loft bedroom space. Designed to be energy efficient and less reliant on the grid than your common home, the Koda comes with solar panels and glazed glass. Kodasema has recently announced that they will be exploring options to use similar construction methods to build office and retail spaces so while you may never live in one, you may start seeing some around in the near future. Prices for the homes start at $111,000.
