Fortis Property Group has closed on its purchase of 30 Front Street from Jehovah’s Witnesses for $91 million, according to property records.

The religious group had used the site as a parking lot, and it was the last remaining property that they had at their former Brooklyn headquarters.

Fortis plans to build a 26-story apartment building with 74 units on the site. The project will span about 250,000 square feet overall, split between 178,000 square feet of residential space and 72,000 square feet of community space.

Fortis is also planning a mixed-use project at 350 Hicks Street in Cobble Hill spanning about 120,000 square feet.

The Jehovah’s Witnesses have sold a total of 37 Brooklyn properties since 2004, according to the religious organization. Other recent deals include the $60 million sale of 74 Adams Street to developer Jeffrey Gershon and the $202.5 million sale of 21 Clark Street to Kayne Anderson Real Estate Advisors.

Neither Fortis nor the Jehovah’s Witnesses immediately responded to a request for comment.
