Rice fields surround the site, with natural riches around such as a national park, a pond of Junsai -a kind of waterweeds threatened with extinction- and bamboo trees. Stretching out east and west, the site bends like a Japanese character ‘く’ with its corner facing north. Roads are on both northwest and south sides; the former is higher than the latter by 1 to 1.5 meters. Not to mention the natural environment, to take advantage of the height differences is the key to enhance the potential of this building.
For the fear of water damage caused by the rice fields and ponds around here after rain, the main approach of this building was taken from the higher road. The entire building, which has a widespread deck terrace, is held up altogether to 1.3 meters from ground level by using steal skeletons, and thus, under-floor-space can be used as open space like a pilotis. Since the ground always has a lot of moisture, it is best to get cross breeze in the space. The use of a lifted concrete base makes ventilation even better.
