text: Treasury officials said the Archives building was their top priority, followed by the Internal Revenue building, two Department of Agriculture projects, and the Commerce building last. At that time, no provision was made to construct a new building for the Department of Justice and no sites were named for construction of the three announced buildings. Preliminary plans for the Commerce building were presented to the Commission on Fine Arts and Public Building Commission in mid-June. On July 7, the Treasury Department and Commission of Fine Arts announced sites and sizes for the three previously announced structures.  The Department of Commerce building would contain 1 million square feet (93,000 square metres) of office space and be sited on the south side of B Street NW (now Constitution Avenue NW) on the National Mall. The Internal Revenue building would contain 650,000 square feet (60,450 square metres) of office space and take up two whole city blocks between 10th and 12th Streets NW and B and C Streets NW (cutting off 11th Street NW). The National Archives would contain 2.3 million square feet (213,900 square metres) of office space, and take up one city block between 12th and 13th Streets NW and B and C Streets NW (cutting off the last block of Ohio Avenue NW). The government owned three of the four plots needed for the Internal Revenue site, but none of the land beneath the proposed Archives building. Purchasing both sites, officials estimated, would cost $700,000 each.  Treasury officials also proposed at this time adding a Justice building on Pennsylvania Avenue between 14th and 15th Streets NW, and a Labor building (facing 15th Street) between 14th and 15th Streets NW and D Street NW and Ohio Avenue NW. Preliminary plans for these buildings were expected to be presented in three months.
