Angular cutaways create apertures through the walls, floors and ceilings of this house in the Bousou Peninsula mountains of Japan by architect Yuusuke Karasawa (+ slideshow).
Divided into eight equal portions, the wooden house was designed by Yuusuke Karasawa as a perfect cube with four rooms on each of its two floors.
Three-dimensional holes cut through the structure at the points where spaces meet one another, allowing views across different rooms as well as between storeys.
"The partition walls and ceilings of these eight spaces are interrupted by six small cubes that create gaps in the walls and ceilings, providing visual connections between the various rooms," said Karasawa.
"Although I spaced the cubes out, the interrelatedness of their angles of inclination connect them, creating a sense of continuity," he added.
The cutaway sections also help to distribute light through the house. "Beams of sunlight come from unexpected directions and crisscross within the interior, bringing out more layers of complexity to the already diverse interior condition," Karasawa said.
Positioned on the eastern edge of Tokyo Bay, the house provides a weekend retreat for a family who play golf at nearby country clubs.
The four ground floor rooms comprise a kitchen, a living room, a studio and an entrance lobby, each with white walls and timber flooring.
A steel staircase winds up to the level above, where a large hallway and two bedrooms are accompanied by a glazed bathroom.
The timber-clad facade features lopsided square windows on each side, offering views out towards the surrounding mountainous landscape.
Other Japanese residences we've featured this week include one that brings light in through the roof, one with a series of small attic spaces and a narrow timber house with paper thin shutters folding out from its walls. See more Japanese houses »
Here's some more information from the architects:
This is a weekend cottage situated within the deep mountains area of midland of Bousou Peninsula. The site is located on Kanou Mountain, Kimitsu city. Traditional Japanese painting artist, Kaii Higashiyama(1909-99) once mentioned that he was awakened to a landscape painting by the majestic ravine scenery of this site-this cottage is sitting on the slope looking down this ravine.
The exterior shape of this building appears to be a simple cube. However, the interior consists of two layers of the traditional square plan, while a cubic volume is inserted to the points of intersection produced by the wall surfaces, the floor surfaces and the ceiling that divide the space.
The intersecting angle of each cube is defined by the rule of an algorithm, producing the most prominent character of this project - that adjacent cubes are tilted in a definite angle against each other.
The rotation angle of the cubes defined by algorithmic rule dissects the interior volume into various spaces according to the header forms of the cutting plane, providing diverse spatial conditions as each individual room.
The interior produced by this method have diverse characteristics for each space although the certain sense of order is given to the whole building since the setting of the cube angle is not random.
This condition allows to experience the coexistence of the order and the diversity as antinomy based on the physical sensation of the space. It can be said that such coexistence of order and diversity is the most significant characteristic of the architectural space produced by an algorithmic rule.
The toplight on the ceiling brings in the sunlight and filled up the room during the daytime. Beams of the sunlight come from unexpected direction and crisscrosses within the interior, bringing out more layers of complexity to the already diverse interior condition.
The initial rotation angle of the cube is fixed according to the slope angle of the site, therefore the magnificent natural scenery is reflected and articulated to the spatial conditions of the interior space. The occupants of the space can feel the sense of unity to the scenery visible outside of the windows.
This weekend cottage was completed under the unique methodology of configuring the spaces - while it exists within the grand nature, and its surrounding scenery is taken into the space. The result would be the new and original physical sensation and experience of the space.
