located in an area of japan known for its international skiing resort, ‘villa in hakuba’ is an adaptable and constantly evolving home which reacts to the region’s changing climate. designed by local practice naka architects’ studio, the dwelling is conceived as an ‘environmental device’, establishing a close relationship with its natural landscape.

contrasting neighboring houses, which set flooring 1 meter above the earth – protecting against snow fall – an uninterrupted ground plane forges a continuous connection with the scheme’s immediate surroundings. living accommodation is located primarily at ground level, where internal space opens out on to the sheltered terrace. bedrooms are found at the upper storey of the home, which provides views across the villa’s woodland setting.

during winter months, the strong double-skin roof is able to take the strain exerted by the vast quantities of snow, while in summer, the transparent polycarbonate material allows generous amounts of sunlight to enter the property. a geothermal heat store situated underneath the floor slab provides the house with a constant source of warmth, while the snow which settles on and around the structure serves as further insulation.
