JLL Completes the $74.6 Million Sale of a Building in Boston’s Seaport for a Life Sciences Conversion


BOSTON – JLL Capital Markets announced that it has closed the $74.6 million sale of a 102,727-square-foot office building to be converted into a life sciences property at 51 Melcher St. in Boston’s popular Seaport District.

JLL arranged the sale with the seller, Zurich Alternative Asset Management, and procured the buyer, a life sciences investor. Additionally, the buyer engaged JLL to source post acquisition financing and lease the property.

The nine-floor building was completed in 1916 as a steel encased in concrete masonry warehouse. Most recently renovated in 2013, the Energy Star-Certified office building has 13.5-foot slab-to-slab clear height.

51 Melcher St. is at the epicenter of the Seaport District, steps from the intersection of A and Summer streets. Multiple transit and commuter rail stations are within a short walk from the property, which is surrounded by restaurant and retail amenities.

According to JLL Research’s recent 2021 Life Sciences Lab Real Estate Outlook, the greater Boston area is the No. 1 life sciences cluster in the U.S. Boston is the indisputable center of life sciences due to its supply of lab real estate dynamics, deep and educated talent pool, innovation and industry depth. Demand for lab space is anticipated to grow, as funding flows, talent and lab space supply grows, and the Seaport has emerged as one of the top life science neighborhoods due to its connectivity to Kendall Square via the Red Line.

The JLL Capital Markets team representing the seller was led by Senior Managing Director Coleman Benedict, Director Scott Carpenter and Associate Mike Shepard.

“Our team is grateful for the opportunity to assist our client in the successful transaction of 51 Melcher Street,” Carpenter said. “Situated in Boston’s most dynamic submarket, the property is an ideal candidate for office-to-life science conversion.”

The JLL Agency Leasing team representing the new owner in leasing the life sciences space includes Executive Vice President Ben Hux and Managing Director Patrick Nugent.
