The project is conceived as an architecture blossomed from the landscape itself, gently resting on the natural slope of the site. It is an ode to water and the waterfall that characterise the landscape and the lush rainforest of Yakushima Island. The house is defined by water: it is its counter-shape and it’s regulated by its flow and states. It is a contemporary living space rooted in tradition and ecosystem. It is an intimate architecture that offers a transformative experience to who inhabits it, by exposing the house to the forest, and by strengthening the relationship between water and the site. It is a hybrid architecture spanning several scales, from the domestic to the territorial, becoming an inhabitable landscape embedded in the local ecosystem. By carefully orienting and positioning the building at the heart of the boundary lines, we identified an opportunity to create a unique spatial and sensorial experience, re-establishing a meaningful link to the ocean along the south-facing coastline. The intention was to establish a tangible connection with water, and it materializes through the rooftop swimming pool: a suspended drop of water above the built space. The water and its container – the roof - provide shelter and anchor the project to the idea that water is the central mediator between architecture, landscape, and daily life.
