80 M Street, a 286,000-sf office building in Washington, D.C.’s Capitol Riverfront district, is set to receive a 105,000-sf mass timber vertical expansion.

The project will become the first commercial office building in D.C. to feature mass timber new construction. The building will use a composite wood product engineered from hardwood grown in the Pacific Northwest. The new floors will feature 16-foot ceilings and 12-foot-high windows, a combination that will allow for double the amount of natural light penetration compared to a standard office.

The expansion will also feature exposed ceilings, polished concrete floors, and myriad connected outdoor spaces that will add nearly 4,000 sf of outdoor amenity space atop the building.
