All The Best Of Park Slope... 3 True Bedrooms, 2.5 Baths, 2 Private Outdoor Spaces, Ideal Location, and a Truly Impressive Building! In 2013, this historic Beaux Arts-style building was thoughtfully transformed into the Park Union, with 15 well-designed and elegant condo units facing Grand Army Plaza and just off of Prospect Park West.
