Modeled after a traditional Welsh cottage, the mini building is two-thirds the size of a real house. It has a thatched roof and whitewashed walls, along with functional plumbing and lighting. Inside is 1930s period furniture and decor. Eighty years after it was built, it still lives on the grounds of Windsor's Royal Lodge.
