In addition, an earthquake safety was studied and a disaster readiness plan prepared. Then the building was renovated to improve disaster preparedness and safety. The elevator facilities and the kitchen facilities were also renewed. Throughout this process, renovations were kept to a minimum and every effort was made to restore the building to its original condition. To ensure that the new structures would blend in with the historical structure, their height was matched to the eaves height and stone wall of the main building. The banquet hall was laid out among the trees on the site of the former pool, and the roof of the existing building that is located between the banquet hall and the courtyard was converted into a pond to gently connect the two structures. The chapel is invariably visible when the Seto Inland Sea is viewed from the main building, but its presence was minimized to the greatest degree possible by placing the air conditioning system beneath the floor and by using a slender 100ø structure that allows the gaze to focus on the courtyard.(Keisuke Nakamura)SITE PLAN　S=1:2000NWorks30aaCbbbdd
