Cambridge, MA Anchor Line Partners, LLC and partner Northwood Investors, LLC have completed a construction milestone for 60 First St. The team celebrated the topping off– placing the last steel beam atop the two-story addition and overall retrofit of their life sciences project located at the former Sears building within the Cambridgeside 2.0 redevelopment. According to Anchor Line, 60 First St. is now 100% leased, ahead of completion.

Located at the intersection of First and Thorndike, 60 First St. is currently undergoing a build out of the existing three stories, as well as a two-story expansion. Upon completion, the building will offer class-A lab/office, ground-floor retail, and a new walkway connecting to the Cambridgeside 2.0 ecosystem in the East Cambridge/Kendall Sq. neighborhood.

Before placing the final steel beam last week, Anchor Line was pleased to welcome two tenants to the 60 First St. community.

Prime Medicine, a biotech startup focused on gene editing, announced earlier this year that they will occupy three floors and approximately 148,000 s/f of the redevelopment.

Korro Bio, a leading RNA editing company focused on the discovery and development of novel genetic medicines, recently announced they will occupy 50,000 s/f at 60 First St.

“East Cambridge continues to prove to be the nexus for finding cures to disease and improving the quality of life for people. It is our mission to provide these companies that are on the frontier of change the environments they need to succeed,” said Andrew Maher, managing director at Anchor Line Partners. “We are thrilled to welcome Prime Medicine and Korro Bio to 60 First St.”

“We’re excited to move forward with plans to relocate Korro’s corporate headquarters to the 60 First St. development in mid-2023. The company continues to grow and we anticipate having over 100 employees collaborating in this dynamic, cutting-edge space, in the heart of the reimagined Cambridgeside area,” said Anna Barry, COO of Korro Bio”

Construction management firm Gilbane Building Company is the GC on this redevelopment.
