Carlyle Gateway I & II is a distinctive inner-suburban office complex comprising two buildings: 333 John Carlyle and 1900 Duke Street. Positioned adjacent to key east-west commuting routes such as Duke Street and the Capital Beltway in historic Old Town Alexandria, the properties offer views of the iconic George Washington Masonic National Museum. With quality architecture and amenities, Carlyle Gateway I & II is a desired location for many businesses. 

In 2019, award-winning renovations to the lobbies, corridors and amenity spaces were completed, further enhancing the appeal and functionality of the buildings for its tenants. 

Sustainability Impact

• Since 2022, we have sourced 100% renewable energy for Landlord controlled meters via Dominion Energy. 
• Our on-site honeybee program includes two active hives. 
• A weekly composting program operates on site.
• Sponsored bike-to-work day and volunteer opportunities with a local park clean up and bagging groceries for residents suffering from food insecurity. Donations of grocery and other retailer gift cards were made to families, seniors, and foster children in need through the City of Alexandria’s holiday program as done in previous years, with more contributions from tenants, vendors, and property management staff.
