House located on the west edge of the plains. In this district, Mt. Yahiko and Mt. Kakuda are above sea level at about 600m as regional landmarks stand between these plains and the Sea of Japan.
The client's hope for the house was that from the window, he would be able to see two mountains that he used to see in his childhood.
However, according to the investigation before designing, we found that even at the second floor level, they could not see Mt. Kakuda due to obstructions from the other house, only Mt. Yahiko. There was a possibility of the view of Mt. Yahiko disappearing as well when if a new house was constructed between the house and the mountain in the future.
Although two mountains' view from the house will disappear, these elements still keep the important identity for this site and their existence that suggests the wider world beyond the narrow space of the site. Thus, I designed this house as a compass that always considered the existence of two mountains while living.
The front sides of the exterior wall are composed of two diagonal sides that are irrelevant with the angle of the site. One is an orthogonal, with the side of its axis toward the center of the Mt. Yahiko from the center of the house, and another is an orthogonalization side of the axis toward the center of Mt. Kakuda.
Those are the orthogonal sides that are ambiguous rather than the accurate orthogonal sides. Because, if they stand at a position away from the center, it shifts from the accurate axis. If the change in the future is assumed, the large windows change from showcasing the "Scenery of the mountain" to "Hint of the mountain" as the prototype in the region that keeps existing without greatly changing even if the surroundings are changed.
And, herein, the two mountains intersect as well.
"The first floor that was enlarged " and "The second floor that was shortened" On the first floor, both ends of the long passage were finished with the mirror. According to the effect of the mirror, the depth of the passage was enlarged far longer than an actual distance. Moreover, the perspective that became narrow toward the inner part was put on a part of the passage. Therefore, the depth was produced long in the first floor more than the actuality.
Bright light was put from the glass window of both sides, so the high illuminance was realized. While, the difference of the luminance results in the blight light emphasising the darkness of the Andean Rose wood board. this occurs because of the difference of the space between the first floor and the second floor was made larger.
The second floor is a space that opens radially toward two orthogonal sides.
The wall and furniture are radially arranged, and the ceiling has an upward inclination from the inner toward the window. According to the reverse-perspective, the depth of the second floor was shortened and they feel the outer environment closer. It makes more conscious of the orthogonal side and "Hint of the mountain" .
Two orthogonal sides with obtuse angle generated the effect that the interior entered in the outer environment. At the same time, according to thrusting out to the town with the obtuse angle, this architecture considered becoming a small landmark for an average town that was lack of the vigor.
