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 will bring two new tenants into the building. GSA entered into agreements with U.S. Bank and 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.

Mobile Workspace

Building 41 has seen a remarkable transformation to a workspace that fosters a mobile work environment. Within GSA space, there are many examples of shared spaces and meeting rooms for all GSA employees to utilize.  In addition, employees work in an open floor plan with mobile workstations, allowing for maximum collaboration.  The wireless network in the building allows associates to work from anywhere.
