Crowded facilities and a desire for an expanded program led to the construction of the Fellowship Hall, which was later used as a temporary Sanctuary in 1963. Later that year, a concentrated Sanctuary building effort was begun.
The Atlanta-based architectural firm of Toombs, Amisano and Wells was selected to design the new Sanctuary. The firm was instructed by the Planning Committee to make the design "dignified, simple and contemporary, with the inside activity determining outside appearance".
