This is a house designed by Igarashi Architects called Case House. It looks simple on the outside with clad that get smaller in height as they get closer to the ground. But when you enter the house, you can see that it looks fun with curving staircases. These staircases connect wooden loft-like floors that spread all over the house. It may looks not save, but it definitely fun to live in this house.
