1111 18th Street, NW

This unique building was constructed to meet the needs of a single high-security government tenant. The six-story, blast-resistant structure was designed to accommodate future building growth of five additional floors on top of the existing structure; the mechanical systems, the elevator penthouse, and other building systems were designed to allow the future five-story addition to occur cost-effectively. The building is located in the heart of the Golden Triangle with easy access to several Metro stations and numerous restaurants, hotels, and retail shops.
