Completed in the year 2000 by Japanese architect Shigeru Ban, the Naked House in Kawagoe provides shelter for a family with five members, including two children and the owner’s elderly mother. The client wanted 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.”

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 precise 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 that 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 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. Through these bags, a soft, diffused light fills in the interior of the house.
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 is a result of my vision of enjoyable and flexible living, which evolved from the client’s vision toward living and family life.
