The 10 Largest Lab/Office Leases In The Boston Area In 2020

For owners of Boston commercial space, 2020 was a year of bifurcation.

The coronavirus pandemic affirmed life sciences' place as the dominant force driving major leasing activity in Boston and nearby suburbs, with anchor tenants securing significant footprints at incoming projects.

But only four office deals topped 75K SF in downtown Boston, the lone bright spots in a rough year marked by rising vacancies, skyrocketing sublease space and employers largely mandating remote work.

“We’re beyond levels we saw in the tech bust,” Colliers Boston Director of Research Aaron Jodka said, noting sublease space in downtown is at a level beyond the Great Financial Crisis of 2008. “That’s probably a better comparison in terms of vacancy.”

Here are the largest 10 lease deals from 2020 in Boston, Cambridge and their immediate suburbs, compiled using data from Newmark, Lincoln Property Co., Colliers and Cushman & Wakefield.

Size: 360K SF
Landlord: DivcoWest
Type: New lease

The year's largest deal came in the midst of the pandemic, with New York-based BMS signing this deal for office and lab space in August. BMS is heading to the project at 250 Water St., which is expected to deliver in 2022, developer DivcoWest said.

The deal is among the largest at the 45-acre site, which earlier this week announced the topping off of the adjacent 350 and 450 Water St. buildings, the future 900K SF home of biopharmaceutical tenant Sanofi.

BMS will use the space to accommodate its business following its $74B acquisition of Celgene in 2019.

The Cambridge-based gene-editing company committed to fully occupy this spec lab building 18 months ahead of a scheduled delivery. The project is the first by Breakthrough, a joint venture of Tishman Speyer and biotech investment firm Bello Capital. Breakthrough purchased the site for $80M in July 2019.

The deal was the largest of the year in the expanding Seaport lab market, with massive purchases by life sciences titans but no nearby lease deals topping 100K SF in 2020.

Lexington-based Translate Bio is moving into a more spacious site in 2021 after signing a 10-year lease with Boston Properties, it announced last month. The messenger RNA therapeutics company will depart the growing life sciences hub in Lexington, representing a difficult loss for the city, Lexington Economic Development Director Sandhya Iyer told Bisnow.

“It’s a homegrown company for us, but they’re moving out to Waltham,” Iyer said. "More money equals more space."
