Mysterious Wreck on Bedford

I smelled this building before I saw it, on Bedford and Gates (1124 Bedford). It's the smell of damp, rotting wood. I've smelled it before when old haunted houses get pried open for renovations.

The place is huge. According to Brownstoner, the building was once the Bed-Stuy Community Mental Health Center. A Google search for the organization puts it currently at 1121 Bedford, just across the street (the same address as the YMCA). How long was this building in use? How long has it been closed?
