Lt. Harold L. Clark conceived a combined structure holding offices, a theatre, signal and photo facilities and a water tower, and Atlee B. Ayres and his son Robert produced the construction drawings. It is the most prominent structure on the base and won an American Institute of Architects award in 1940.","narrative":"Building 100, nicknamed the \"Taj Mahal,\" is the administration building at Randolph Air Force Base near San Antonio, Texas. Built between July 1930 and July 1931 for about $252,000, it combines two office floors, one-story wings, a 1200-seat theatre and a 147-foot octagonal tower capped by a blue and yellow glazed tile dome. The tower encloses a 500,000-gallon water tank. Lt. Harold L. Clark, who trained as an architect, drafted the concept and merged several separately funded facilities into one structure. Local architects Atlee B. Ayres and his son Robert prepared the construction drawings and adapted the design to the Spanish style common in South Texas. The firm received a 1940 American Institute of Architects award for the work. The building has served as headquarters for the Air Corps Training Center and later flying training wings, and it remains in use with its exterior unaltered and its original terrazzo floors intact.","period_of_significance":"1930-1931","architect_builder":"Atlee B.
