The project draws from the ecological conditions and atmospheric qualities of Yakushima Island. Situated between the dense, biodiverse forest floor and the openness of the sky, the house occupies an in-between condition that reflects the layered character of its surrounding environment.

The architecture establishes a clear relationship between ground and sky. Living spaces are lifted above the natural topography and oriented toward the highest mountain peak in Kyushu, while the roof curves downward to frame the forest canopy and sky beyond. This configuration organizes views both horizontally and vertically, allowing daylight to be drawn deep into the interior.

The roof is the key architectural element and is supported by three solid structural punctures that anchor the building to the site. These elements manage rainwater during Yakushima’s wet season, mediate the connection to the adjacent pool, and organize entry through a sequence of compression and release. Nature is central to the spatial structure of the house: the main living space is arranged around a meditation garden, reinforcing the building
