Corbett planned a three-story memorial temple topped by a three-story tower. The first three floors (which constituted the temple and the base of the tower) would be built in the Neoclassical style, while the tower would be a variation on the setbacks popular in Modern architecture .  The structure was to be built entirely of masonry , with almost no metal used in its construction (except for reinforcing rods in the concrete).   The rationale for this decision was that a building constructed purely of stone would be the most permanent structure possible.   The firm of Osgood & Osgood of Grand Rapids, Michigan , was the consulting engineer.    Daniel E. Moran (of the firm Moran, Maurice & Proctor of New York) designed the building's foundation; Gunvald Aus was the structural engineer; the firm of Clarke, McMullen & Riley (of New York) was the mechanical engineer; and Carl Rust Parker of Olmsted Brothers was the landscape architect .  The general contractor was the Percy Cranford Co., but the actual masonry work was done by the Samuel Miller Co. (both companies were located in Washington, .).
