Description
Welcome to Residence No. 1 at 511 Eighth Avenue 3 Bedrooms 2 Bathrooms Duplex Recreation Room Private Outdoor Space Residence No. 1 at 511 Eighth Avenue is an expansive three-bedroom, two-bathroom duplex offering 2,302 square feet of interior space, a generously proportioned recreation room, and two distinct private outdoor areas in the heart of Park Slope. Thoughtfully designed across two levels, the residence combines the scale and flexibility of townhouse living with the convenience of a condominium. The main living level features white oak hardwood floors throughout, complemented by a refined material palette and a layout that balances comfortable everyday living with entertaining. At the front of the residence, the living room flows seamlessly into an expansive kitchen and dining area. The kitchen features custom cabinetry, generous counter space, and a premium Fisher & Paykel appliance package. A substantial center island provides additional workspace and seating, while the adjoining dining area comfortably accommodates a full-sized dining table. Three bedrooms are positioned toward the rear of the main level, creating a natural separation between the living and sleeping areas. The primary bedroom is generously proportioned and features an en-suite bathroom. Two additional bedrooms offer flexibility for family, guests, or a home office, with a second full bathroom conveniently located nearby. Outdoor living is a defining feature of the residence. A 318-square-foot private courtyard extends along the side of the home, offering an inviting setting for outdoor dining, lounging, and entertaining. At the rear, a separate 240-square-foot landscaped yard provides an additional private retreat. Together, these two outdoor spaces offer exceptional versatility and a seamless connection between indoor and outdoor living. The lower level is dedicated to an exceptionally spacious recreation room, measuring nearly 56 feet in length. This expansive space offers tremendous flexibility for a media lounge, playroom, home gym, or additional entertaining area, with ample room to accommodate several distinct uses. A dedicated laundry area with washer and dryer, along with additional storage, completes the lower level. Situated along Eighth Avenue in the heart of Park Slope, the residence enjoys close proximity to Prospect Park, neighborhood cafés, restaurants, independent boutiques, and the conveniences of Seventh Avenue. With its tree-lined streets, historic architecture, and vibrant neighborhood atmosphere, Park Slope remains one of Brooklyn's most desirable places to call home. The complete terms are in an offering plan available from the Sponsor (File No: CD26-0124).

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
