Listing Notes

Park Slope luxury and charm meets modern functionality and design at 123 Sixth Avenue, a brand new boutique condominium offering four floor-through homes with private outdoor space. The building sits on a 40-ft wide lot and maintains many of the enchanting details it had when constructed in 1880. An alluring brownstone facade with a bold cornice and tall arched windows belie exquisite, spacious interiors that exemplify contemporary elegance and refinement. Each 3-bedroom home is a timeless expression of the classic Brooklyn lifestyle. Natural light spills through Pella Reserve double-hung windows onto beautiful chevron-pattern hardwood floors. Open-concept layouts accentuate decorative fireplaces and stunning eat-in kitchens equipped with massive islands, custom Marfa cabinets, sleek Cambria quartz countertops and backsplashes, chic Hansgrohe faucets, and high-end stainless steel appliances from Viking and Liebherr. Bathrooms are outfitted with stylish tilework, custom floating vanities, Toto toilets, and Hansgrohe shower fixtures. All homes come with a washer/dryer and ample private outdoor space in the form of a backyard or rooftop deck with built-in grilling stations. 123 Sixth Avenue has a virtual doorman system and private stroller and bike storage. Nestled on a quiet residential street in the northern corner of Park Slope, the building is close to Grand Army Plaza, Prospect Park, Barclays Center, BAM, Prospect Heights, Boerum Hill, and Downtown Brooklyn. There are dozens of restaurants, bars, cafes, and shops moments away, and nearby subway lines include the 2/3/4/5/B/D/N/Q/R. Pets are welcome.
