Building 41 was originally constructed in 1941 as part of an ammunitions plant. The building has been upgraded to office and warehouse space over the years. Today, the two-story, red brick building offers a mix of office, conference, warehousing and food service space.

Recent changes include two new tenants into the building. GSA entered into agreements with the USGS to backfill the newly available spaces off the main lobby of Building 41. The USGS is in the planning stages to relocate a reference library off the main lobby of Building 41, and build-out is scheduled to commence within the next few months. U.S. Bank recently opened its doors in spring of 2013.
