Located in a quiet neighborhood in Tokyo, “The House in Sakuradai” belongs to three households. Before the house was built, a one-storied house, which eventually became two stories, had been lived in by two generations for decades. As time passed, the composition of the residents changed, and a single family remained. The structure of the house that linked the first and second floor by a staircase did not function well after the changes of lifestyle, and the gap between what was required and what existed widened.
In addition to the modification of family structure, the local societies in Japan are facing rapid change because of an aging population and low birthrate, and the effect plainly appears in the increasing ratio of vacant houses. Today, the previous form of housing no longer maintains people’s standard of living, and it is has become necessary to rethink flexibility in living environments.
The structure of both families and local societies will change inevitably. The major goal with this project is to prepare the ever-renewing living environment which enables inhabitants to create the place of living freely, and thus preventing an altered structure and estranged lifestyle.
Contributing to the house’s originality is that its residents freely select and combine the “small houses” to form the place of living by themselves and are actively open to the society around the house.
The whole architecture consists of a simple composition, and is made by the so-called “small houses.” Each small house is different in shape, size, and materials. However, upon viewing each small house block, they do not differ much from the surrounding houses, owing to the fact that a) the form of house and roofs (gable, pent, and flat) are induced from the context of neighborhood, and b) common materials are used such as lysine mortar and wood. Therefore as a whole, this architecture can easily mingle with the neighborhood’s atmosphere.
“Small houses” have openings in all directions, and are able to build new relationships with the adjoining houses. Each small house can be accessed from the outside directly, therefore the architecture has possibilities to become a triplex, a rental house, a shared house, part atelier, or a public space.
Moreover, the small houses are independent construction-wise, which enables extension, reduction, reconstruction, and remodeling simultaneously, and that allows the house to continue to exist in a transitional status. Like living cells in a human body, the series of the small houses will modify the balance of whole architecture even if inconvenient elements invade because of the change of program. Consequently, this house will connect inhabitants’ life and local community to achieve a rich social environment. People living in this house are constantly in the process of creation which enables renewal, and will blaze a trail for an unknown future.
