The project at 600 13th Street NW required a complete building repositioning effort. The original structure was built in 1996 and needed significant upgrades in order to re-enter the downtown DC marketplace as a Class A structure. A series of paralleled projects included the main level and lower level lobby renovation, elevator replacements, a new roof terrace, core restroom renovations, and a new fitness center.


Highlights of the project include a new curtain wall and main building entryway. The state-of-the-art curtain wall system was designed and constructed to integrate an LED panel behind frosted glass which wraps the interior of the archway entrance. The new lobby areas feature new stone, wood, metal and glass finishes, such as the Travertine flooring and the limestone wall paneling. An existing curved stairway was demolished and a new metal and glass feature stair connects the two lobby levels. The build-out of the new fitness center on the concourse level received all new finishes and MEP systems for the work-out area and dressing and shower facilities. There was also significant structural alterations to the roof area for the construction of a new terrace with custom decking, lighting and public space upgrades.
