Description

Welcome to 84 6th Avenue, an exquisite two-bedroom, two-and-a-half-bathroom duplex condominium where timeless Brooklyn architecture meets thoughtful, high-end renovation. Nestled within a beautifully restored 1884 Neo-Grec brownstone in the Park Slope Historic District, this nearly 1,700-square-foot home offers an extraordinary combination of indoor comfort and rare private outdoor space. Meticulous design choices abound—from the wide-plank white oak floors and soaring ceilings to the Pella windows and custom millwork that elevate every room. The open-concept great room is both welcoming and functional, anchored by a bespoke chef’s kitchen featuring custom oak cabinetry and a full suite of Bertazzoni appliances. Whether entertaining or unwinding, the seamless transition to the 734-square-foot private yard—with its mature trees, elegant fencing, and generous patio—is an undeniable highlight. The king-size primary suite is a true sanctuary, offering two closets and a serene en suite bath clad in floor-to-ceiling statuary marble, complete with a walk-in rain shower and refined brushed nickel fixtures. A well-proportioned second bedroom and beautifully appointed guest bath with soaking tub round out the main level. On the lower floor, a sprawling recreation space adapts easily to your lifestyle—as a media room, playroom, office, or third bedroom—complemented by a chic powder room, full-size washer and dryer, and custom dry bar with wine fridge. Residents of this boutique brownstone enjoy modern conveniences including Central HVAC and ButterflyMX virtual doorman system, all while being moments from Prospect Park, Grand Army Plaza, and Park Slope’s best dining, shopping, and cultural destinations. With convenient access to multiple subway lines and the LIRR, the entire city is at your doorstep. This is brownstone Brooklyn living at its most refined—classic, curated, and completely turnkey.
