Welcome to a exquisite penthouse retreat in one of Brooklyn's most sought-after neighborhoods, this duplex gem offers a rare combination of soaring space, incredible light, and premier outdoor living. Located at the edge of JJ Byrne Park and perched atop a discreet 10-unit, elevatored condo, apartment B-5B is defined by its dramatic double-height ceilings and massive two-tiered windows. The result is a home bathed in natural sunlight throughout the day. Completely renovated by the owners before they moved in, the layout is excellent for modern living. A main living space includes an open kitchen with plenty of counterspace, a dry bar seamlessly built in under the stairs, room for an 8 person dining table and a cozy living room all bathed in indirect light from a double height wall of windows. There is a full width balcony right outside the sliding doors with a barbeque and sitting area. At the other end of the apartment are two spacious bedrooms, a long hallway of closets, a walk-in laundry room with side-by-side vented units and overhead storage, and a shared bathroom. Walk up the dramatic staircase to the primary suite where you'll find a lofted space with room for home office and/or reading nook. Through a door you enter the primary suite with two large custom closets and a renovated en-suite bathroom. There is room for a king bed and additional furniture. Don't need 3 bedrooms? This also makes an excellent den and extension of the living space with separation available when needed. Outside the sliding doors is a southern facing, private roof deck with sweeping views of Park Slope and it's gem, JJ Byrne Park. With room for a dining table, lounge, BBQ and plantings, this can be your outdoor oasis. Is this too much sun for you? There is a motorized shade already installed to comfort while you sip a cool drink and hang with friends and family. This incredible penthouse was designed with luxury in mind. Accessed directly from a key-locked elevator, it boasts European oak floors, Nest-controlled central HVAC, a private laundry room with full-size washer/dryer, and a custom bar with a 75-bottle wine fridge, automatic shades and custom closets. The owners recently installed a new boiler and water heater for a move-in ready and worry free transition. Let's not forget, Location, Location, Location! 353 3rd Street is central to the best of Park Slope. You are directly across the street from the vibrant J.J. Byrne Park and the historic Old Stone House, giving you a ""front yard"" of lush greenery, playgrounds, and community events.
