The Bloomhouse was designed and built by architects Charles Harker and Dalton Bloom when they were students back in 1984—and since then it’s been compared to everything from a seashell to a unicorn. It was restored in 2017 and has become arguably one of the world’s weirdest rental homes. Located in a wooded valley on the outskirts of Austin, Texas, the whimsical home is all sinuous curves and sweeping organic lines. As the Airbnb listing puts it: “Without one straight line or corner in the entire structure, your thoughts are free of the constraints that our angular world creates.”
