The Boston-based developer delivered the 21-story office building in 2021 and netted $83 million by selling its stake to joint venture partner Bernstein Cos.
BXP sold a 50 percent ownership interest in the corporate headquarters building for Marriott International in downtown Bethesda, Maryland, at a $430 million valuation. The Boston-based real estate development and management firm sold its stake to joint venture partner The Bernstein Cos., generating net proceeds of $83 million. CBRE brokers Tommy Cleaver, Bill Shanahan, Dan Grimes and Chloe Neal represented BXP in the sale.
BXP delivered the 21-story office tower in 2021. Marriott fully debuted the tower in fall 2022. The building holds LEED Gold and Fitwel certifications.
The property features a rooftop terrace, a grand lobby with an LED wall and three-story atrium, a 7,500-square-foot fitness center, collaboration space, two dining offerings, an 11,000-square-foot childcare center, and an innovation center with a test kitchen. The office tower can accommodate roughly 3,500 workers across 2,842 workspaces, according to Marriott.
"This remarkable headquarters is the result of a shared vision and a strong partnership with BXP," Adam Bernstein, president and CEO of The Bernstein Cos., said. "Together, we delivered a world-class building for Marriott International's global headquarters."
BXP, formerly known as Boston Properties, is a real estate development and management firm based in Boston. The company trades on the New York Stock Exchange under the ticker BXP. The Bernstein Cos. is the acquiring partner in the joint venture.
The Deployment Angle

The transaction prices the full asset at roughly $123,000 per worker or $151 per square foot based on Marriott's stated capacity of 3,500 employees across 2,842 workspaces. That figure assumes standard office space ratios and gives a rough building size near 2.8 million square feet. The $430 million valuation on a recently delivered, fully leased corporate headquarters in a strong suburban D.C. market suggests sponsors are willing to harvest equity at pricing levels that underwrites to mid-single-digit unlevered yields, reflecting confidence in long-term anchor tenancy and the quality premium commanded by LEED Gold buildings with extensive amenity packages.
For family offices considering office exposure, this deal illustrates the route through co-GP capital alongside established developers with strong tenant relationships. BXP's $83 million net proceeds on a 50 percent stake implies the developer likely recouped most or all of its development equity while retaining a joint venture governance role through the original delivery. A family office entering at the same point would underwrite tenant credit, lease duration, and the building's operational efficiency given its high amenity load and the fixed costs that accompany childcare centers and test kitchens.
The sale also marks a recapitalization rather than a full exit, which signals BXP's view that the asset warrants holding but not sole ownership. Family offices considering similar structures should model liquidity paths and capital call obligations if the remaining partner pursues refinancing or further asset management. The valuation at this stage reflects stabilized cash flow, not speculative lease-up, so returns hinge on expense control, tenant retention through lease renewal cycles, and the ability to sustain premium rents justified by the amenity offering.
