Please note floor plan coming soon! Welcome to this truly exceptional three-bedroom, three-bath duplex residence spanning nearly 1,800 square feet of refined living space. Enter into an expansive, sun-drenched living, dining, and kitchen area where south-facing windows fill the space with warm natural light throughout the day. Wide-plank white oak floors run seamlessly through a dining area that comfortably seats six, leading into a sprawling living room that features an ethanol-burning fireplace against a backdrop of wall to ceiling windows offering views of the everchanging seasonal colors. You will immediately notice that this home has been impeccably cared for by its first and only owners. At the heart of the home is a chef-caliber kitchen, appointed with crisp white stone countertops, including a dramatic waterfall-edge island, and fully outfitted with top-of-the-line Wolf and Sub-Zero appliances. Real cooks will appreciate the oversized sink with garbage disposal, instant boiling water tap, and filtered water on tap. An in-cabinet Wolf microwave and Bosch dishwasher complete this gourmet setup. Tucked toward the rear of the home, the king-sized primary suite offers a peaceful retreat with a spacious walk-in closet. The primary bathroom is marble-clad with sleek Duravit fixtures, Kohler hardware, floating vanity and toilet. Radiant heated floors and a heated towel rack ensure comfort all year long. The secondary bedroom on this level is equally as impressive offering oversized dimensions and excellent closet space. A second full bath is located off the main hallway and features a striking chevron-tiled floor, deep soaking tub, along with similarly refined Duravit and Kohler finishes. Across the hall, you'll find a proper laundry room with full-sized washer and vented gas dryer-an increasingly rare convenience. Downstairs, this dramatic third room is currently used as an office space/rec room. With soaring generous proportions, 12-foot ceilings, a full private bath, and walk in closet, and its own private entrance, this room offers incredible flexibility. And when it's time to entertain or unwind outdoors, head up to your expansive private rooftop escape-fully equipped with a gas grill featuring infrared burners, running water, irrigation, and mature juniper trees that create a lush, elevated oasis in the sky. 277 1st Street is a rare, boutique elevator condominium made up of just six homes. Built in 2017, this exclusive building offers its residents geothermal heating (included in the common charges!), Samsung SmartThings keyless entry, filtered water throughout, private storage rooms, and even a small gym. Nestled just off vibrant 5th Avenue, you're moments from Park Slope's best shopping, dining, and transit. Reach out today for a private showing of this rare and remarkable home.
