japanese residence by airhouse encloses minimalist interior of sloping floors and walls
diagonal lines make up the house in Kodaira
House in Kodaira, Tokyoby Japanese architecture studio Airhouse, is a minimalist residence defined by diagonal lines. Its geometric exterior in white hues alludes to the particular composition of the interior spaces, where floors and sloping walls come together in a playful yet rational union. On the ground floor, three-meter-high plants are installed at the entrance, while multiple steps divide the space into planes of different heights. Large custom windows let plenty of natural light into the space, which is painted in white and off-white hues. The white concrete kitchen blends with the walls, while pops of color on the fabrics and furniture add to the cheerful atmosphere of the house.

A PLAFUL INTERIOR BY AIRHOUSE
Airhouse determined the geometric shape of the residence by designing the diagonal lines of the floors and walls with dimensions divisible by 303mm, 455mm, 910mm, ‘observing the magnitude of the wooden shakkanho method.’ Additionally, by dividing the wall diagonally, the architects wanted the interior wall to be secure as much as possible for storage and workspace, while the exterior side of the wall can maximize space for greenery and to get on and off the car. Inside, the slanted walls also create a playful interplay of light and shadow that wouldn’t otherwise happen. The different steps that define the floor of the ground floor contribute to the progressive division of each spatial space. Additionally, each step provides seating and also functions as a device for communicating while sitting in various locations.
On the upper level, the private rooms are connected by a bridge wide enough to be used as a work or leisure space. ‘It looks like you can use it as a second living room, because you can feel the connection with the whole family in terms of the cross section,’ notes Airhouse.
