DUMBO loft features two generously sized bedrooms, a beyond spacious home office (which can serve as a third interior bedroom), a secondary work from home space, and two and a half bathrooms. This home boasts breathtaking views of the Brooklyn Bridge, Manhattan Bridge, Downtown Manhattan Skyline, Empire State Building, East River, and Brooklyn Bridge Park. Surrounded by walls of oversized windows that wrap around the entire home, beautiful dark stained hardwood floors, 11’+/- high concrete beamed ceilings, and an open floorplan is a true definition of what DUMBO loft living truly is. Upon entering this stunning home, you approach a gracious gallery-style foyer leading into the main living space. The expansive, nearly 48-foot-long open living and dining area seamlessly blends everyday living with effortless entertaining. This open, airy space is framed by picturesque views and enhanced by custom built-in radiator covers with window seating. Additionally, there is a custom built-in media center with additional storage. The fully renovated, open-concept chef’s kitchen is the heart of the home, anchored by a striking 2-inch-thick Imperial Danby marble center island with generous seating. It's outfitted with top-of-the-line appliances, including Thermador double ovens, a Thermador cooktop, a Sub-Zero refrigerator, a Bosch dishwasher, a garbage disposal, and a filtered water system. Ample storage is provided by sleek custom cabinetry and a built-in pantry conveniently located just off the chef’s kitchen. The expansive en-suite primary bedroom showcases spectacular northern views, perfectly framed by oversized windows. It includes a large custom-fitted walk-in closet with additional overhead storage and custom built-in radiator covers with window seating. The en-suite bathroom features a deep soaking spa tub, a separate walk-in shower, and a double vanity with a marble countertop. The sun-drenched, west-facing second bedroom offers three oversized windows, a spacious custom-fitted closet with additional overhead storage, and CitiQuiet windows for enhanced soundproofing. The second full bathroom is conveniently located directly across the bedroom. Rarely found is the size and scale of the home office/interior third bedroom, offering exceptional versatility. Currently used as an interior sleeping space, this room features custom fitted closets and custom built-in storage throughout. Rounding out this spectacular loft is a formal laundry room featuring a brand-new LG washer and dryer with custom built-in storage throughout, a half bathroom, and an additional versatile interior room with custom built-ins—ideal for a work from home space. The home also includes central A/C and hot water heating. Originally built as a factory in 1916, The Sweeney Building is now the true classic residential loft building offering a 24-hour attended lobby, friendly staff, a bike room, a newly-renovated gym, basement storage, and a breathtaking roof deck with sweeping views. Located in the heart of DUMBO, The Sweeney Building is in proximity to the famed Brooklyn Bridge waterfront park, Janes Carousel, new Empire Stores, award-winning playgrounds, DUMBO Boulders rock climbing, the A/C/F trains, and the water taxi. Celebrated for its architecture, DUMBO features charming cobblestone streets, cozy cafes, restaurants, shops and renowned art galleries.
