House in Yamanashi – UENOA Create a Functional Home for a Family of 5

Based in the Yamanashi Prefecture of Japan, this home focuses on creating a series of functional living spaces for its occupants. The designers had to accommodate the needs of the owners and their three young children.


The project was taken on by the Japanese firm UENOA, lead by architects Yoshinori Hasegawa and Fumie Horikoshi. Together they’ve produced a quiet contemporary property, that’s fitting for the family.

The house itself is finished in a mix of white with light wood. Elements of the timber structure are also on show at various points, particularly on the upper level, where the large beams supporting the roof have been left exposed.

The house has a kinked floor plan. The ground floor contains an open plan living room, dining area and kitchen to one end. The other end features a Japanese style bathroom, entryway and a Japanese room with tatami mats.
