Overview of The Tracy Mansion at 105 Eighth Avenue

The Tracy Mansion is a 1912 Park Slope condominium conversion of a 50 foot wide mansion designed by Frank J. Helme. Its landmarked neoclassical façade has a rusticated limestone base, a curved central bay framed by Corinthian columns, a bronze and glass arched entrance, and a marble paneled foyer. Originally built for the Tracy family, operators of the M & J Tracy cargo and tugboat company, the property later served as a Knights of Columbus meeting house and the Park Slope Montessori School before its conversion to seven residences in 2017.

The three story, mid block building retains its formal stoop, landscaped front yard, marble entry, wood detailing, stained glass, oversized windows, fireplaces, and high ceilings, while rear additions and a penthouse were incorporated into the residential conversion. A grand interior staircase was featured in HBO’s Boardwalk Empire. The building has central air conditioning, in unit washers and dryers, a screening room, and outdoor entertainment space.

The residences are organized in spacious layouts that include duplexes, garden apartments, and a penthouse. Apartments commonly have ceiling heights ranging from roughly 9 feet 10 inches to 12 feet, wood burning or gas fireplaces, and private outdoor space such as gardens, terraces, patios, or balconies. The penthouse occupies the top floor and opens to a large private terrace with western light and skyline views.

The Tracy Mansion is on Eighth Avenue between President and Carroll Streets, one block from Prospect Park. The surrounding area includes the Grand Army Plaza Greenmarket, Brooklyn Museum, and Brooklyn Botanic Garden, with the park and its cultural institutions forming the immediate setting.
