Shin-urayasu Terrace-house Renovation

This project was a renovation for a townhouse in Irifune Chuo Estate, a danchi in Urayasu City, Chiba Prefecture, Japan.

NOTE: Danchi is the Japanese term for multi-unit, residential buildings grouped together so as to provide the various kinds of infrastructure needed for domestic life and to optimize logistics.

Many danchi were built between the 1950s and the 1970s, which was the highpoint of Japanese economic development.

Irifune Chuo Estate was built in 1979. It is located about five minutes’ walk from Shin Urayasu Station on the JR Keiyo Line.

Over 35 years have passed since the building was constructed, but it possesses many of the strong points unique to old danchi, such as the generous size of the plot in relation to the size of the building and a pleasant environment with well-maintained gardens. This danchi is also popular because many of the features of its construction make it different to the standard danchi. It has two story townhouses with their own gardens, or duplex apartments, for example.

The client had spent time living in USA, and purchased this townhouse because its reminded him of the house he had lived in at that time. His wish was to renovate the residence so that it would be suitable for family living. Also, because the client is planning to move in about five years’ time and will put the property up for rent, he also expressed his desire to have the residence designed in such a way that it would appeal to people who are particular about their living space.

Another request that had a fundamental impact on the design plan was for sanwacompany products to be used as much as possible in the design of the space. We made extensive use of the company’s ready-made goods, not only for hygiene-related fixtures such as the toilet, basin, and kitchen fixtures; and for finishing materials such as flooring and tiles; but also with doors, windows and the like, which largely come in standardized sizes.

The overall design plan included the removal of a wall that originally divided the passageway and the kitchen-dining-lounge area, and the remodeling of this area so as to create a spacious and expansive space. The toilet, which had been under the stairs, was shifted to be alongside the basin. The wet areas (toilet, basin, bathtub) were brought together and made more compact, creating a simple arrangement. (The bathtub, toilet, kitchen, and basin were all replaced with new fixtures.) The area under the stairs was enlarged to create a space that could be used in as many ways as possible. It contains the washing machine area, and storage for clothes, seasonal items, cleaning equipment, and so forth.

Decking was installed outside the window that lets gorgeous sunlight into the kitchen-dining-lounge area. This allows the family to access the garden area directly, without worrying about a change of footwear, as is the custom in Japan.

So as to keep construction to a minimum on the upper floor, we removed the tatami and installed other flooring into one of the Japanese style rooms, turned the Japanese style closet into a western style wardrobe, and created a bedroom.

From the outset, the residence enjoyed plenty of sunlight and good views from both the first and second floors, but by removing the extraneous walls, we were able to create a home that is even brighter and feels even more spacious.
