Drina River in Serbia
According its owner, “this house was built in 1968. It was not easy to build then. But I finally made it happen with the help of my friends.” Back then they were just a bunch of young boys who loved to swim in the waters of Drina River and sunbathe on the large rock that now supports the house. Its lumpy surface wasn’t the most comfortable to sit on, so one day they decided to build a proper place to rest. They started bringing in planks from a nearby derelict shed, and before long they had actually built a cosy shelter complete with walls and a roof. It may not look very sturdy, but this wooden home has survived several floods and serious storms.
