The Portals

Washington, DC

The Portals

One of the largest projects in the history of the Nation’s Capital, The Portals is a $1 billion mixed-use development representing the last major Urban Renewal project to be constructed on sites in Southwest Washington, DC. This monumental undertaking was also the largest mixed-used project offered by the DC Redevelopment Land Agency, the District’s key development arm.

The scale of The Portals required extensive negotiations and coordination with numerous government agencies and private entities in its design and development, including the Commission of Fine Arts, National Capital Planning Commission, Consolidated Rail Corporation (“ConRail”) and the DC City Council.

Development of The Portals included building an elevated extension of Maryland Avenue over railroad tracks, transforming a previously unsightly area into an elegant gateway with commanding views of the Capitol, the Jefferson Memorial, the Tidal Basin and the Potomac River. The $150 million, 440,000 square foot Phase I of The Portals is principally occupied by agencies of the United States Government, related private contractors, and CareFirst. Phase II represents a $200 million investment totaling approximately 600,000 square feet. The Phase II building is 100% leased to the U.S. Government and serves as headquarters for the Federal Communications Commission and will become the future home of the Pension Benefit Guarantee Corporation.  The Phase III building is more than 500,000 square feet located on the northeastern portion of the site, and is principally occupied by agencies of the United States Government.

In 2004, the 400-room Mandarin Oriental Hotel opened on-site, featuring luxurious and spacious accommodations including 51 suites, significant meeting space including an 8,300 square foot pillar-less ballroom, a restaurant, a lobby lounge and a cocktail bar.  The hotel further differentiates itself with the introduction of the Mandarin Oriental’s Spa Collection – a highly personalized, full-service spa and health club with indoor pool and deck.

There are two remaining phases to be delivered.  1331 Maryland Avenue, which delivers in the Spring of 2019, will be a sophisticated 373-unit, 14-story building offering sweeping views of the National Mall and the U.S. Capitol, as well as the Jefferson Memorial, the Tidal Basin and across the Potomac River to Virginia.  Designed by New York-based Robert A.M. Stern Architects (RAMSA), the distinguished design for 1331 Maryland pays homage to the architectural character of the Southwest neighborhood and the monuments and office buildings of D.C.’s Federal Center.

The final phase of The Portals is currently planned to be a Class A office building.
