BOSTON — Columbia Property Trust has secured more than 50,000 square feet of new leasing activity at 116 Huntington Avenue, underscoring continued demand for high-quality office space in Boston’s Back Bay as companies in artificial intelligence, life sciences and professional services expand their footprints in the city.
The six recently completed leases at the 273,000-square-foot boutique office tower include two major expansions from long-term tenants and four additional commitments from fast-growing firms across the AI, pharmaceutical and healthcare sectors.
“This momentum is a reflection of the quality of the building, the thoughtfully cultivated environment we’ve created, and the strength of the Back Bay market,” said Ted Koltis, Executive Vice President and Head of Real Estate at Columbia Property Trust. “The addition of cutting-edge AI and life sciences companies alongside expanding long-term tenants is exactly the kind of tenant mix that makes this building a top choice in the market.”
The largest transaction came from Karen Clark & Company, a software development firm that has operated at 116 Huntington since 2017. The company expanded its headquarters by 8,022 square feet and now occupies the entire 20,286-square-foot 10th floor. Karen Clark also signed a four-year lease extension that will keep the company in the building through at least 2032.
Longpoint Partners, a real estate private equity firm and tenant since 2015, also expanded its presence at the tower. The firm signed a 3,031-square-foot headquarters expansion and relocated to the 12th floor, where it will occupy 11,053 square feet under a new 10.5-year lease extension.
The remaining deals highlight growing demand from innovation-driven industries.
Formation Bio, an AI-native pharmaceutical company, signed a 6,172-square-foot lease for a newly built preconfigured suite on the second floor. SciVida, a life sciences-focused management consulting firm, leased 5,462 square feet on the third floor, while OnCorps, Inc., an AI platform specializing in fund operations, doubled its office footprint by relocating to a 4,155-square-foot suite on the ninth floor.
MD2 International, LLC, a concierge medical provider, also signed an 11-year lease for 3,306 square feet on the ninth floor.
The leasing activity comes as Columbia continues investing in tenant amenities at the 15-story property. In 2025, the company unveiled The Clubhouse, a 6,400-square-foot amenity center featuring a fitness facility, conference and meeting rooms, lounge space, kitchen facilities and a Full Swing Golf Simulator.
The recently LEED Gold-certified tower also includes efficient floorplates, on-site parking and a two-story atrium lobby with direct access to Jaho Coffee. Existing tenants at the property include Silversmith Capital Partners, CVS and The Segal Company.
Located in Boston’s Back Bay neighborhood, 116 Huntington Avenue sits within walking distance of the Prudential Center, Boston Common and the Freedom Trail, while offering direct access to MBTA subway and commuter rail stations, major highways and regional transit connections.
Columbia Property Trust handled the transactions in-house through Ted Koltis and Maria Blake alongside JLL brokers Dan Cavanaugh, Patrick Nugent and Maeve Cleary. Tenant representation across the deals included brokers from JLL, Colliers, Hughes Marino and other firms.
