Overview of The Tracy Mansion at 105 Eighth Avenue

The Tracy Mansion is a distinguished Park Slope landmark, originally designed by Frank J. Helme in 1912. This Neo-Classical building features a striking façade of marble, characterized by rich stone detailing, Corinthian columns, and a grand arched doorway. The mansion has been transformed into seven luxurious condominium residences, each offering a unique blend of historic charm and modern amenities.

Originally built for the Tracy family, who operated a cargo and tugboat company, the mansion has a storied past, including its use as a meeting house and a Montessori school before its recent conversion. The building's elegant design includes a marble-paneled entry foyer and a landscaped front yard, enhancing its appeal as a residential property.

The condominiums within the Tracy Mansion boast spacious layouts, with many units featuring high ceilings, wood-burning fireplaces, and private outdoor spaces. Notable apartments include a three-bedroom duplex with a grand great room and a master suite that spans the width of the building. Each residence is equipped with modern conveniences such as in-unit washers and dryers, central air conditioning, and high-end kitchen appliances from brands like Sub-Zero and Wolf.

Located just one block from Prospect Park and close to public transportation, the Tracy Mansion offers residents easy access to the vibrant cultural and recreational amenities of Brooklyn. This unique property combines the grandeur of a historic mansion with the comforts of contemporary living, making it a rare find in the competitive Park Slope real estate market.
