“It seem to be small space, but which cause to feel big. ” “It seem to closed space, but which is opened to other space. ” “It seem to be internal space, but which makes you feel being external space. ” We have tried to include such as conflicting sensations, and create various and rich spaces. So we considered that "Make a ‘house’ in a house". First, we designed inside liberating space like outside. Next, we designed a BOX (‘house ‘) enclose only the required privacy features in the house. Thereby, small ‘house’ with different levels are appeared in the inside space, and which create a new space rich and diverse. These new spaces gently connect family relationship and make the boundaries vague.
