Just like a tea ceremony house or a Japanese sukiya garden, the view to the north looks beautiful in the sun. Although one might have the impression that a north-facing house is simply dark, in fact it is quite the opposite, with the outside space playing the leading role. It is also an ideal location for a summer mountain villa.

　The facade of the house is clapboarded in gray to match the surrounding tree trunks. There are only two openings in this wall. A large window on the right side of the front façade reveals a white interior wall illuminated by top light and Douglas-fir rafters, indicating a bright interior space. To the left is a gate-like entrance, through which one encounters the view for the first time.


The entrance is located adjacent to this terrace, and from here one enters under the roof that hangs along the slope of the mountain. As you enter, you will see a large floating wall beam on the left side.
This wall beam supports the roof and also serves as a reflector, reflecting light from the top light along this wall beam and illuminating the living room below as indirect light.

While the light from the top light is bright, the heat can be a problem, but in the plateau it has a great advantage: it brightens the room, which tends to be dark surrounded by trees.
　As you descend the staircase, the view in front of you unfolds like a gondola floating on a plateau.

　The main space with the living room is a 5.4m square section with a ceiling height and width cut diagonally across the top, and the flat surface is a 5.4m x 9.1m golden ratio rectangle. The plan is composed of a5.4 m x 9.1 m rectangle with a golden ratio. This gives the interior space a sense of fullness and richness, and the people inside feel a sense of relief as if they are being embraced. The interior wood, both structural and finished, is all reddish Douglas fir, which contrasts with the white painted walls.
