80 M Street SE

The District’s first commercial office building to feature mass timber construction, 80 M Street incorporates the use of cross-laminated timber to add two full floors of showstopping trophy class office and penthouse space to an existing 7-story building.

Build Boldly

Columbia Property Trust sought to create incremental value for investors by capitalizing on the building’s unused floor area ratio (FAR) square footage. In partnership with Davis Construction, Arup, and JLL, we successfully pitched a cross-laminated timber addition, reasoning that the increase in construction costs could be offset by a higher per-square-foot lease rate, and together, began a conceptual design to take to market.

An impressive ceiling height of 17-feet and expansive 12-foot-high windows provide unparalleled open space and natural light penetration in the DC commercial market. A floor-to-ceiling glazing wrap enhances the material’s biophilic nature and provides street views of the penthouse’s all-wood interior and exposed ceilings. A connecting stair, polished concrete floors, and nearly 4,000-SF of connected outdoor amenity space aided in attracting a high-profile tenant before design development even began.

Why Mass Timber?

The building’s lobby, shared amenities, and a collection of spec suites received an upgrade that complements the addition and highlights the use of mass timber to meet the needs of the post-pandemic workforce. The biophilic-inspired environment alludes to the timber above, including a sculpture of laminated veneer lumber panels in the entry arcade and flexible workspace maximizing natural materials balancing open and perimeter offices to maximum daylight.

We're Just Getting Started

What began as a passion project resulted in the first mass timber addition in the nation’s capital. Having realized mass timber’s potential, we’re eager to apply what we’ve learned to future projects and forge a path towards mainstreaming mass timber in the building industry.
