The architects sought to open the views towards the north of the site, while simultaneously implementing the house's ground level one metre higher than the neighbouring road level. "It is as if the site's natural environment and the architecture coexisted at the same time," states UID's Keisuke Maeda. "The architecture has become a part of the whole landscape of undivided environment, not simply thinking about connection to the surroundings from the cut off openings in walls."
"We came up with a living form that accepts the outside environment," continues te architect, "such as the surface of the terraced land, surrounding neighbouring houses' fences and walls, residences that sit along the slope and far beyond mountains."
The volume's key principle hinges on an interior conceived as the extension of the outside space, with six types of floor levels, including a round floor, with a concrete cylinder core at the centre. Multiple branch-like columns supporting a series of floating boxes produce diverse spaces.
In the Pit House, environment and architecture are intertwined by connecting surfaces, which allow the territory to become undefined and fluid.
