Newmark Completes Sale of Four-Building Campus Park 9 in Wellesley to Beacon Capital Partners


Boston — Newmark announced the sale of Park 9, a four-building campus with life science conversion potential in the suburban Boston community of Wellesley, Massachusetts.

Newmark Co-Head of U.S. Capital Markets Robert Griffin, Executive Vice Chairman Edward Maher, Vice Chairman Matthew Pullen and Managing Director Samantha Hallowell of the firm’s Boston Capital Markets Group represented the seller, BentallGreenOak on behalf of Sun Life, and procured the buyer, Beacon Capital Partners.

Totaling 375,058 square feet, Park 9 encompasses four buildings with high-quality office interiors and abundant modern amenities plus a six-story structured parking garage. It is anchored by three long-term, credit-rated office tenants—Sun Life, Morgan Stanley and Boston Children’s Hospital—and features a 120,000-square-foot asset that is well positioned for immediate laboratory conversion.

“Park 9 offers the exact type of self-contained, amenity-rich, mixed-use campus environment that appeals to life science users,” said Maher. “The park further benefits from a highly-visible, strategic location in the southwest quadrant of suburban Boston’s key Route 128/Route 9 interchange.”

In addition to Route 128 and Route 9, Park 9 facilitates swift access to Interstate 90 (Massachusetts Turnpike), which provides a direct connection to both Cambridge (13 miles away) and Boston (16 miles away). The campus is also situated between two public transit routes—the MBTA commuter rail’s Framingham/Worcester line and the MBTA Green Line’s D branch—that connect to the city.

Newmark Senior Financial Analyst William Sleeper provided financial analysis support on the transaction.
