80 M Street, SE is located in Washington DC’s Navy Yard neighborhood. The first of its kind in the city, the project scope includes a mass timber vertical extension to an existing seven-story building. The renovation adds two full floors of trophy-class office space with 16’-0” floor-to-ceiling heights. An occupied penthouse level will add additional office density as well as a rooftop terrace and shared amenity space.

Valued for its biophilic and sustainable qualities, global interest in mass timber has spiked since it was first developed in Europe in the 1980s. Due to a robust lumber supply, the engineered material has already garnered a significant following in parts of Canada and the Pacific Northwest. Now, as mass timber construction gains momentum along the east coast and within major metropolitan areas, members of the real estate and urban planning communities seek to advance their knowledge of the material’s structural requirements, capabilities, and benefits.

Recognizing the enormous potential of mass timber, architecture and design firm Hickok Cole launched an internal research program exploring its viability in the District of Columbia. Following a series of DOEE-funded grant reports, design prototypes, and studies, Columbia Property Trust presented the firm with an opportunity to put their research to the test, resulting in the development of 80 M Street, Washington, DC’s first-ever mass timber addition to an office building. As mass timber advocates, Hickok Cole and its partners, including Arup and Davis Construction, have continued working with local jurisdictions to educate the industry and progress the city’s building codes to further facilitate the material’s widespread use.
