日本老旧住宅翻新，木结构体量打造舒适生活空间

大阪的建筑事务所OFEA（office for environment architecture）于近日完成了一个住宅的更新改造项目。该项目位于日本九州岛的佐世保市，初建于20世纪60年代，是一个建在山坡上的单层建筑体量，被一片住宅建筑所环绕着。随时时间的推移，这座住宅变得越来越老旧，更重要的是，其室内空间还会受到严寒和酷暑的影响。此外，虫害也是这座住宅所面临的问题之一。

Osaka-based firm OFEA (office for environment architecture) has renovated a house in sasebo, a city on japan’s kyushu island. The previous property, which dated back to the 1960s, was a single storey structure built into a hillside and surrounded by neighboring properties. However, the house had begun to show its age, and was affected by extreme cold in winter and extreme heat in summer. There were also problems with insect infestations.

本住宅的屋主是一位年轻的女子，她从她的祖父那里继承了这座年迈的住宅。OFEA的领导者norio yoshinaga决定帮助她对该住宅进行一次彻底的更新改造。除了要改善住宅的保温隔热性能，建筑师还希望建筑能够与它周边的环境更好地融为一体，同时让住户欣赏到山下一览无余的美景。此外，本项目还作为一个典型案例，探讨了“在闲置房屋增多和老龄化越来越严重的情况下，我们可以做些什么”的问题。

Consequently, Norio Yoshinaga, who leads OFEA, was tasked with renovating the property for its client — a young woman who inherited the residence from her grandparents. In addition to improving insulation, the architect also sought to better integrate the structure with its surroundings and offer sweeping views across the neighborhood below. The design also serves as an example of what can be done in a country that suffers from a growing number of empty houses and an aging population.

Importantly, a new timber structure has been used to reorganize the home’s interior.

这个具有保温隔热性能的体量内设有一个厨房空间和一间起居室，贯穿了原住宅的中轴线。随后，木结构自起居室继续向前延伸，形成了一个室外露台。这个露台不仅提供了绝佳的景观视野，更为重要的是，在炎炎夏日里，它还能够将凉爽的微风引入室内，拉近了居住空间与外部自然环境之间的关系。

This insulated volume runs through the center of the dwelling and contains a kitchen and living room. The corridor culminates in an external deck, which frames views of the landscape and brings cooling breezes into the home in summer — providing a closer relationship with the natural environment.

住宅的其他房间如卧室等保持原位，位于木结构体量的两侧。

Other areas of the home, including its sleeping quarters, are found in adjoining rooms that form part of the previously existing property.
