Property Description
Welcome to 351 Union Street, Unit A. Offering the scale and privacy of townhouse living with the ease and convenience of a condominium, this exceptional triplex spans 2,124 square feet of thoughtfully designed interior space. With three bedrooms, two full bathrooms, and two powder rooms, the residence pairs refined finishes with a warm, contemporary aesthetic and a highly functional layout. Private outdoor spaces include a landscaped backyard and a spacious terrace just off the kitchen. The open Porcelanosa kitchen is beautifully executed, featuring walnut and lacquer cabinetry, quartz countertops, and a suite of premium appliances, including a Bertazzoni range and hood, Liebherr French-door refrigerator, Bosch dishwasher, Bosch speed oven, and wine cooler. A dramatic 10-foot island with a deep sink anchors the space, creating a natural focal point for cooking, gathering, and entertaining. The parlor level is defined by soaring 11-foot ceilings and an effortless flow between the kitchen, living, and dining areas. Floor-to-ceiling windows and sliding doors bathe the space in natural light while opening seamlessly to the terrace, creating an indoor-outdoor experience rarely found in condominium living. The result is an airy, inviting environment that lives like a brownstone. All three bedrooms are on the garden level, offering quiet and tranquility. The primary suite is complemented by a spa-inspired bathroom with a glass-enclosed rainfall shower and double vanity. The secondary bedrooms share a beautifully appointed full bath with a deep soaking tub and custom cabinetry. Wide-plank hardwood flooring and bespoke walnut millwork add warmth, texture, and continuity throughout. The finished cellar level has full ceiling heights and is a generous recreation space. It's an ideal space for a media room, lounge, gym, or playroom, and features a powder room, laundry room, and substantial storage. Central air conditioning and a video intercom system complete the home's modern comforts. Set on a picturesque, tree-lined block surrounded by classic brownstones, 351 Union Street is perfectly located near dining, shopping, and the café scenes of Smith and Court Streets. With Carroll Park and the subway just moments away, this residence offers the best of both worlds: elevated townhouse-style living with the simplicity of condo ownership in the heart of Carroll Gardens.
