Description

A home that challenges our preconceptions of urban living—Residence 3B at 450 Warren combines light, landscape, and distinctive design into the center of everyday life. Entering the building’s light-filled atrium and crossing your own private outdoor foyer, there’s an immediate sense of intention—no conventional enclosed hallway, just open, green, thoughtfully designed space. Inside, the bright and open living area feels connected to its surroundings, with natural light and garden views drawing your eye outward. An expansive terrace off the living area extends the space for dining, entertaining, or a quiet moment outside. Considered the building’s most desirable two-bedroom line, the B-line pairs south and west exposures with views over the natural garden. Trees and greenery are visible from every window. The kitchen sits at the heart of the home, open to the living and dining areas so cooking and gathering happen together. Custom Portuguese pink marble brings a striking focal point to the space, while hardwood floors and exposed concrete add warmth and architectural character throughout. A dishwasher and the conveniences of a modern kitchen fit naturally into this carefully considered setting. Across the residence, the architecture creates an easy exchange between interior and exterior: step out to the terrace, look across the planted atrium, or simply enjoy the trees framed by the windows. The primary bedroom offers its own retreat, opening directly to a second expansive terrace. A custom wood-paneled wall brings texture, softness, and warmth to the room, while the greenery just outside lends it a sense of calm. A walk-in closet provides generous storage. That feeling of ease continues into the spacious primary bath, with double sinks, a custom marble counter, and a large, open, spa-like shower. The second bedroom is a flexible room ready to take on whatever life calls for. It works beautifully as a full-time bedroom or guest room, but could just as easily become an office, den, or creative space. An additional built-in office nook provides a dedicated place to work, leaving the second bedroom free to evolve over time. The second full bath includes a soaking tub. An in-unit washer and dryer, central air with discreet linear diffusers, and ample storage throughout the home make everyday life feel as effortless as the design. 450 Warren offers a distinct way of living. Built around a large outdoor atrium, its open-air walkways, shared gardens, and planted spaces replace the usual experience of moving through a residential building. Its architecture has made it a standout among Brooklyn’s most design-forward residences, with a seamless relationship between indoors and outdoors that carries from the common spaces into the homes themselves. Residents also enjoy a shared garden and rooftop lounge with views of Downtown Brooklyn and Manhattan, a co-working lounge, fitness room, pet washing station, and bicycle storage. Set in Boerum Hill near Cobble Hill and Carroll Gardens, the building is surrounded by some of Brooklyn’s most inviting streets. Pick up coffee or settle in with a book at Anaïs, meet friends for dinner at Rucola or French Louie, or stop by Rice & Miso for a casual lunch. The shops and restaurants along Court Street, Smith Street, and Atlantic Avenue put neighborhood favorites within easy reach. For trips farther afield, the F train at Bergen Street and the A and C trains at Hoyt–Schermerhorn offer convenient connections across the city.
