text: The first design contract for any of the buildings in Federal Triangle was statutorily required by Congress in 1926 as part of the Public Buildings Act. A new headquarters for the Department of Commerce had been proposed in 1912 and a contract for the design work awarded to the architectural firm of York and Sawyer. Although this building was never built, Congress honored the contract and named the firm again as the Commerce building's designer. By March 1927, government officials had already decided that the Commerce building should be 1,000 feet (305 metres) long—making it the then-largest building in the District of Columbia.  The May 1927 work moratorium, however, put these plans on hold. In September 1927, the design of the Internal Revenue building was handed over to Louis Simon at the Treasury Department, and the Commission of Fine Arts met to discuss proposed plans for both the Commerce and Internal Revenue buildings. At the same time, the commission received bids on demolition of existing structures in the Triangle.
  After review by the Board of Architectural Consultants, the Public Buildings Commission gave final design approval on November 1, 1927, to the Commerce and Internal Revenue buildings. The previous sizes of both buildings was reaffirmed, as was the "Louvre plan" for a unified ring of buildings surrounding a traffic circle and plaza. The Commission on Fine Arts adopted a requirement that the planned Federal Triangle buildings have a "uniform appearance" and height (six stories), limiting the Board's deliberations. Secretary Mellon imposed a requirement that all the buildings be built in the Neoclassical architectural style. By mid-December 1927, the design of the Archives building had been approved, and the Board of Architectural Consultants was meeting again to study once more the general layout of the Federal Triangle.
