Not only is it unique from the outside, but walking through its doors, you can experience what it's like to see the world from a bat's perspective, and see its interior upside down, making it an interesting experience for all ages.
Of course, the interior of the house has been turned upside down, and every detail of the interior is inverted. And during their time there, they can enjoy the effect of an upside-down world on their sense of balance.
Come and play with gravity!
