What makes the house in these photos so unusual is that it has moving walls in an attempt to make it as safe as possible. When the house is open to the garden toward the west and east sidewalls, an outer courtyard is created. A person can’t get in through the garden or go through the main entrance of the building. The owners must wait for a certain period of time after the opening to the security entrance. Therefore, when the house is closed, the security zone protects the building.
