The cube house in Rotterdam is one of the Rotterdam landmarks and is probably a selling point in Rotterdam. Tickets are three euros/person, to be honest, there is nothing special inside, there is a small three-story building, the stairs are steep to death, there should be no difference in living, and the difference with a normal house is that the window is tilted, and then there will be a lot of bevels in the house, According to the Chinese habit of living is not a good house. But this square house is indeed inhabited. In my opinion, this house should be bought and opened for people to visit. It is cool to sit and wait for the money every day.
