It was only the fifth time the government had signed a "lease-to-own" agreement. With 1.4 million square feet (130,200 square metres) of office space and 500,000 square feet (46,500 square metres) of space for trade center activities, the planned trade center would be larger than any other federally owned building except for The Pentagon. The bill also required that the trade center be "designed in harmony with historical and government buildings in the vicinity, ... reflect the symbolic importance and historic character of Pennsylvania Avenue and the Nation's Capital, and ... represent the dignity and stability of the Federal Government." A nine-member panel was established to approve any plans, and included the Secretaries of State, Agriculture, and Commerce; the Mayor of the District of Columbia; and five members of the public.
