The farmlands in the meadows of memu, near hokkaido, enjoy beautiful natural scenery accompanied by extremes in climates. kengo kuma and associates therefore modeled their 'experimental house' after the traditional chise dwellings, or earth houses, that used natural materials to insulate and recover the heat created from the indoor fireplace to maintain comfortable temperatures throughout the entire winter. the construct recalls a barn typology, but differs vastly in material use.  a double skin membrane is composed of a polyester fluorocarbon tarp on the outside and a glass-fiber cloth membrane on the interior, insulated with polyester insulation from recycled PET bottles. the idea is not to create the thickest,most solid insulation possible, but rather to use the material properties to perform in the desired way. allowing light to create a diffuse day-lit glow, the interior enjoys a perfectly lit space that exposes the larch frame structure of the home, all the while maintaining a constant temperature.at night the house is illuminated from the interior, as the radiant floor heating is only necessary to acclimatize the space once every few days. the house becomes a member of its context, changing with the seasons and responding to the different conditions inside and out.
