Project DescriptionThe Marriott Marquis Convention Hotel will be located in downtown Washington D.C adjacent to Mt. Vernon Square and the Washington D.C. Convention Center. The existing historic Plumber’s Union (American Federation of Labor - AFL) building will remain on the corner of Massachusetts Avenue and 9th Street and become a separated guestroom tower connected at the lobby and at the 4th floor of the project.
The project consists of a number of subterranean floors housing meeting and assembly spaces accessed through a main hotel lobby located at grade. 1,166 hotel guestrooms will occupy 13 levels above the lobby with additional meeting and amenity space at several levels. The roof will house mechanical equipment in a penthouse. The exterior materials and the architectural character of the building will be compatible to the area and to other newer buildings on and around Massachusetts Avenue. The guestroom tower begins at level two, which will provide an executive conference area within the domed atrium space. The guestrooms are planned with full Marriott Marquis amenities and service. A full service health club “ultra-lounge” is planned within the guestroom tower with views to the atrium and to 9th street below. Parking for 400 vehicles is to be located underground.
