The Teilhard de Chardin Complex is a conference-exhibition-housing facility located immediately south of the East Crescent. Its two large basilicas and  large number of smaller conference rooms will provide Arcosanti with considerable capacity for seminars and conferences. Twelve small housing units will be built along the top of the cloister, with an open-air theater below. The buildings will connect directly with the Energy Apron Greenhouse located on the south slope.
