□Prerequisite The lot is located in a residential area and is surrounded by neighboring housings, with a mother's house on its west. Requests for the house include: encourages the family to spend time together (rather than isolating anyone) / spatial / bright with plenty of natural light.
□Plot The family space is arranged at the center of the site. （fig.01） The private space is arranged at the edge of the site , and they connect gradually by the one volume. （fig.02） Distance among rooms and curved spaces provide adequate privacy. （fig.03） Each rooms are indistinctly connected to each other via central space. （fig.04）
□Indistinct That indistinct connection is the key concept of this house, expressing the spatial relationship (not on/off relationship) among the rooms. Like a photo out of focus.
□Invisible one room You can grasp the space visually if the entire space is visible. You can let your consciousness develop the space if not all is visible. Like walking in a path, not sure of what is ahead.
□Ambiguously Spaces divided by straight lines relate to rationally. Spaces connected with curving lines relate to ambiguously. Like a drop of milk in coffee.
□Connection What interests us is how rooms connect to each other, more than how a room is made. What interests us is the “air” that curves, crosses, and diffracts. Like a cloud, constantly moving without having definite shape.
