Spiral Garden House designed by Ryuichi Ashizawa Architects associates
The house combines locals timber dwelling construction with a unique form, consisting of a continuous spiral that rises towards the central space. The inner and outer walls were first clad with woven bamboo lattice, its walls and floors then covered with Sanwa Earth finish. The floor uses a technique called Tataki. In the winter, during the day the earth-covered walls and floors absorb heat from the exterior. At night the heat is released, keeping the interiors warm. During summer, due to stack effect created by the height difference between the central space and the rest of the house, wind flows from the exterior towards the center and cools the interior From the entrance.
