This building is located on the opposite side of "the 33 Earth monument " commemorating 133.33 east longitude and 33.33 north latitude. The ground height of the site was about 1m higher than the surrounding ground due to the embankment that had been done since there's grandfather's generation. In view of the fact that most of the wooden houses were washed away with only the foundations, we planned to use a high-floored concrete foundation in addition to this ground height to prevent flooding in the event of a tsunami, while maintaining the same wooden flat houses as before the reconstruction.
