A Fort Point office building has been sold to a San Francisco investor for $74.6 million with plans for a lab conversion.

GI Partners acquired the 102,727-square-foot office building at 51 Melcher St. from Zurich Alternative Asset Management and plans to convert the 1916 structure for lab uses, JLL said. The building was originally constructed as a warehouse and has 13.5-foot clear heights.

Zurich has selected JLL to lease the property and source post-acquisition financing.

JLL’s Capital Markets team of Senior Managing Director Coleman Benedict, Director Scott Carpenter and Associate Mike Shepard represented the seller. The leasing team includes Executive Vice President Ben Hux and Managing Director Patrick Nugent.
