Herbert Hoover Building, Department of Commerce Headquarters - Site Improvements and Perimeter Security
(File number 7355)

NCPC commented favorably on concept designs submitted by the General Services Administration (GSA) to add perimeter security and other site improvements to the Herbert C. Hoover Building, headquarters of the U.S. Department of Commerce.

Plans call for the majority of elements to be located inside the building's property line and not in public space including the sidewalks. Proposed elements include a cable rail system that will mostly be incorporated into stone-clad walls and piers, hardened flag poles and lights, bollards near building entrances, and vehicular barriers.

Among its comments the Commission recommended that GSA simplify the overall security design by decreasing the number of elements, develop a pattern and style so the elements better align with the building's architectural features, refine the cable rail details so they better complement the building and landscape's architectural and historic components, and modify some of the security elements' spacing to improve pedestrian passage.

Located at 1401 Constitution Avenue, NW, the Hoover Building is listed on the National Register of Historic Places. In addition to the Department of Commerce, it also houses the White House Visitor Center and the National Aquarium. When it opened in 1932 it was the largest office building in the world.
