Hidden rooms inside of houses may call to mind fantasy novels and movies where the many plot point is magic, but in reality, more houses have them then you’d think. In fact, even if a house doesn’t have one, it’s not that hard to build: All you need is a little space, a little construction experience, and a cleverly placed bookshelf or two. The 31 homes and buildings below all have incredible hidden rooms. Some were built at the same time as the house, and some were added for a little extra hidden charm. Either way, after you’re done looking at these photos, having a hidden room in your house will be a new life goal.
