Completed in 2000 by renowned Japanese architect Shigeru Ban, the Naked House in Kawagoe was designed to accommodate the needs of a family of five, including two children and the owner’s elderly mother. The client desired a living space that prioritized family unity, providing minimal privacy to foster a shared atmosphere for individual activities. The Naked House represents a unique approach to family-oriented design by Shigeru Ban.

Having met the client only once, I was again considering what to do about this house’s project when the client sent me a facsimile making specific requests. What he wanted was described as a house that “provides the least privacy so that the family members are not secluded from one another, a house that gives everyone the freedom to have individual activities in a shared atmosphere, in the middle of a unified family.” After reading his fax, I knew I should take up this challenge.

The house’s site sits by a river and is surrounded by fields with greenhouses here and there. The external walls are made of two sheets of corrugated fiber-reinforced plastics, and the inner walls made of nylon fabric are both mounted on wooden stud frames and sit in parallel. In between are attached clear plastic bags, carefully stuffed with strings of foamed polyethylene for insulation purposes. A soft, diffused light fills the house’s interior through these bags.

The house consists of one unique ample space of two-story-high in which four private rooms on casters can be moved freely. To reduce weight and optimize mobility, these rooms are not very large and hold a minimum of belongings and fittings.

They can be moved according to the needs of their use. Placed against the house walls, in front of the heating or air-conditioning units, warm air or a cooling breeze can flow into it. They can also be put side by side and create a larger room when their sliding doors are removed. They can be taken outside, on the terrace, for the full use of the space inside. They can also work as a supplementary floor for the children to play on top.

Indeed, this house results from my vision of enjoyable and flexible living, which evolved from the client’s vision of living and family life.
