The 799 9th Street project was a complete building repositioning project, consisting of a complete demolition and renovation of the exterior facade and building entrance, a two-level storefront window system, a renovation of the main level and elevator lobbies, a new fitness center, core restrooms, and all new MEP and fire safety systems throughout the building. A roof deck was also completed during the project schedule.


The demolition and re-installation of the curtain wall system on 9th and H Streets NW commanded intricate scheduling and coordination with building management and existing tenants. Additionally, the exterior work, which took place during the cold winter months, required the team work with the Department of Transportation and the DC government in order to maintain safety for the tenants and pedestrians at this busy intersection. A temporary exterior structure was built in order to house all of the curtain wall construction. The design accommodated the existing precast conditions, yet introduced all new glass for the two-story storefront system. The lobby renovations introduced all new finishes to the space while remaining fully operational. The stone in the lobby flooring is a Swiss Silver stone that was sourced in Switzerland. The team took over a dozen trips to the quarry in order to review blocks for consistency in color and veining. A complete drylay of the stone was completed for a week prior to installation, ensuring a seamless end product.
