The Fort Greene firehouse where Oscar-winning director Spike Lee once rented an apartment to house his production company is back on the market.

The building, converted into two loft apartments in the 1980s, is asking $4.9 million. (The listing can be purchased as a two-family spread for income potential, a single-family conversion, or as a live/work space.)

The property, at 124 DeKalb Ave. — formerly Engine Company 257 — is on the corner of Fort Greene Park. It comes with a two-car garage and old firehouse features, like a shaft that runs the height of the building that was used to hang fire hoses to dry — space that could potentially be expanded to install an elevator.

The three-story home is 5,775 square feet, 25 feet wide and 77 feet deep. Built in the 1920s, it also features original Art Deco details, like etched glass panels, oak/marble trim and barrel vaulted ceilings.

A firehouse residence is rare but not unique in New York. CNN host Anderson Cooper owns a former Manhattan firehouse at 84 West Third St., which he bought for $4.3 million in 2009.

The Fort Greene listing broker is Citi Habitats’ Sarah Adler.

Brooklyn’s legendary Gleason’s Gym — where everyone from Muhammed Ali, Mike Tyson and Floyd Mayweather have trained — is opening a residents-only boxing ring at Quay Tower (below). Champion boxer and rabbi Yuri Foreman will offer two small group classes per week and he will also be available for private lessons. He is also creating special classes for kids.
