nagoya-based studio AUAU (akitoshi ukai) has completed ‘ysy’, a two storey residence in seto, japan. bound by a jagged road on one side and a densely populated forest on the other, the project sits on a small hill and features an asymmetrical form that complements the physical conditions of the site.
in context
finished in a matte-white material, the house is wrapped in a shell-like skin that is pushed and pulled from the main volume to create a dynamic identity. the facade is peeled back to accommodate a semi-sheltered entrance while the hitched roofline opens up to a generous window to the city below. by manipulating the verticality of the interior, the openness and privacy of each program is coordinated.
approach
exterior view
to maintain a sense of open space, the living spaces are divided and defined by changes in levels: a mezzanine loft and a kitchen / dining area that overlooks the storey underneath maintain visual connections throughout the house. expansive windows towards both nagoya and the forest provide natural daylight for the interior.
