A speculative lab conversion in Watertown that demonstrated the life science industry’s willingness to grow in Boston’s inner-ring suburbs has been sold for $157.6 million.

New York-based Clarion Partners acquired the LINX complex at 490 Arsenal Way this week from Boston-based Boylston Properties.

Construction of the building shell was completed in spring 2017 and Kendall Square-based C4 Therapeutics signed on as the first tenant in July 2017. Additional leases by Macrolide Pharmaceuticals in October 2017, Addgene in January 2018 and Aileron Therapeutics and Kala Pharmaceuticals in March 2018 brought the building’s occupancy rate to 100 percent.

HFF’s Coleman Benedict, Ben Sayles, Kerry Hawkins and Sam Campbell represented Boylston Properties in the sale, while Cushman & Wakefield was the leasing representative.

The 185,015-square-foot office and lab complex was converted from a former Verizon warehouse. Boylston Properties paid $13.5 million to buy the property from Prologis in 2014.
