Overview of 84 Sixth Avenue

84 6th Avenue is a historic Neo-Grec brownstone built in 1884, located in the Park Slope Historic District of Brooklyn. The four-unit boutique condominium building underwent a meticulous renovation that preserved its architectural heritage while incorporating modern amenities. The original 20-foot-wide structure features restored period details including wainscoting and a historic interior vestibule.

The building was thoughtfully converted to condominiums with landmark-approved modifications including custom French doors with Emtek brass hardware. Each residence features high-end finishes including Bertazzoni appliances, wide-plank white oak floors, and marble bathrooms. Modern building amenities include central HVAC, private storage units, and a ButterflyMX virtual doorman system.

The building's units range from full-floor residences to duplexes, with some featuring private outdoor spaces. The penthouse unit boasts 13-foot ceilings and two private terraces with 360-degree views of Brooklyn and Manhattan. All apartments feature open-concept layouts with expansive living spaces measuring over 30 feet from kitchen to front windows.

Situated between Prospect Place and St. Marks Avenue, the building offers prime access to Park Slope amenities including Prospect Park, Grand Army Plaza, and multiple transit options. The location provides easy access to the 2/3, B/Q, and 4/5 subway lines at nearby stations, as well as the LIRR at Atlantic Terminal.
