"The Yatsugatake Annex is a 43-square-meter weekend residence in Hokuto, Japan, designed by Takanori Ineyama Architects and completed in 2017. It was built for a couple who primarily live in Tokyo but spend weekends and holidays in the mountainous Yamanashi prefecture, and the home is intended to be a comfortable secondary base for their family of five, including three children. The design is a clever response to the surroundings, where the site is relatively large but still located in an area with villas and residences. To achieve privacy while maintaining a connection to the environment, the architects designed the house to open or close to the surroundings, a strategy described as ""closing with one wall"". The house is L-shaped and wrapped with a light-toned wooden exterior that conceals the more private areas while creating an open central living area. The layout was designed to give new value to the site by properly placing different personality spaces, such as the living and dining areas, within an environment created by the ""one wall"". Inside, the home has a minimalist and warm aesthetic, featuring light-toned wooden walls and ceilings. A mezzanine level with an open, airy feel offers unique views and an elevated space for relaxation or play.
