514 Thames St Groton, CT 06340

520 Thames Street presents a rare opportunity to acquire a highly functional, strategically located office asset in the heart of southeastern Connecticut's most dynamic employment corridor. Situated directly across from General Dynamics Electric Boat, the region's largest and most stable economic driver, this three-story, 10,510 square foot building offers a compelling investment profile for both owner-users and investors alike. With 9,575 square feet of professional office space and an additional 935 square feet of dry storage, the property is ideally suited for medical, governmental, or professional tenants seeking proximity to the submarine manufacturing hub and surrounding institutional employers such as Pfizer and Lawrence + Memorial Hospital. The building's durable construction-steel frame, brick masonry, and clear-span floor plates-along with 35 off-street parking spaces, sets it apart in a market with limited high-quality inventory. Recent growth at Electric Boat, including billions in federal contracts and site expansions to support over 15,000 employees, continues to drive robust demand for nearby office space. With updated lease rate assumptions, stable income potential, and favorable zoning, 520 Thames Street offers immediate value and long-term upside through targeted lease-up and minor cosmetic improvements.
