Business is officially closing in the Steel City -- Antonio Brown's Pittsburgh mansion with a pimped-out tree house is up for grabs ... and it can be yours for $2.3 MILLION!!
Things went south REAL quick in Pennsylvania for AB ... so it's no wonder he's trying to part ways with the pad. But, aside from all the drama, the place is dope.
The home comes complete with the 2-story tree mansion, it also has a custom basketball court (which might need a makeover if a Steelers fan cops the place), a turf field, home theater, gourmet kitchen, gym and a sauna.
