About the Hoover Building
When President Herbert Hoover laid the cornerstone of the Commerce Building in 1929 the employees of the Department of Commerce were scattered between twenty different buildings. Tasked with advancing economic growth, jobs, and opportunities for the American people, the Department experienced rapid growth in its first three decades (1903-1933), most significantly under the direction of Secretary Herbert Hoover. Designed by the New York architectural firm of York & Sawyer, the new Commerce headquarters building was completed in 1932 and proclaimed the largest office building in the world with over 3,300 rooms and 1.8 million square feet of office space. It covers 8 acres and 3 city blocks and boasts 5200 windows, 1.5 million face bricks, 99 acres of plastering, two tons of copper nails, and 25 tons of bronze hardware.
