House in Kodaira – A Humble, Functional Home by KASA Architects

Originally built in 1923, this small Japanese family home has undergone renovation works in order to make it suitable for a couple in their 50s. Set in the Kodaira district in the suburbs of Tokyo, the house contains a total of 850 square feet (79 square meters) of living space spread over its two levels.

The revamp was designed by local architecture studio, KASA Architects, and they’ve simply dubbed the project the “House of Kodaira”. The first task set to them by the clients was to remove all of the internal partition walls dividing up the space and to create a bright comfortable environment.

Other requirements from the clients included introducing plenty of light without compromising on their privacy. For this reason the ground floor windows were kept modest in size. On the upper level, with the balcony blocking the view from the outside, the windows are much larger; they’re effectively floor-to-ceiling windows.

From the outside the house looks quite basic – there are no architectural flairs, or decorative elements. The same applies to the interior, but a show is made of the timber structure. It’s a familiar theme in Japanese architecture; the emphasis is on simplicity, with various types of wood and the structure often being used to create a contemporary, homey atmosphere.

The first floor contains the kitchen, dining room and bathroom. There’s a short entrance hallway and a second entry to the side with a pantry. A small study/office nook has also been incorporated into the kitchen, with a timber panel acting loosely as a divider.

The upper level contains the home’s two bedrooms and a walk-in closet. The living room has been placed on this level so as to take advantage of the extra light and views (and privacy). A second toilet can be found to the rear of the living room, and to the front you’ll find a generous balcony.

  1. Japanese minimalism is so very beautiful and restful to my eye. I never find it boring or sterile. I have been unable to discipline myself to achieve it in my homes. I have too much art, too many objects on display. thank you for this post to re-inspire me.

  2. How funny. On the plans the toilets are marked as “ravatory room”, and omg they can’t blame us westerners for taking the mickey either.

    Made my day…!
