The shape of the upside-down roof resembles an open book, making it a bookstore.
The exterior of this building is upside down, but everything inside is normal.
There are bookstores on both the first and second floors, and there is a garden on the roof.
You can read a book leisurely in the rooftop garden.
There is also a toilet on the first floor.
Since the upside-down house has very few parts in contact with the floor, a lot of attention was paid to its durability. It’s made stronger than expected.
