The ACS designed, prefabricated, and installed building features cedar siding and cultured stone rockwork. Inside, the washrooms are equipped with faucets that dispense enough water for washing when touched. Rainwater, caught from the roof, is stored in a cistern in the basement and distributed by electric pumps that are powered by batteries charged by photovoltaic panels in the roof. A ground tube air cooling system helps lower the temperature in the toilet rooms during the summer (the region is lush, but hot and humid)
