65 Montague Unit 3D/4D is a home like no other. Bathed in natural light and spanning two gracious levels, this beautifully renovated duplex offers an exceptional sense of space and scale in the heart of Brooklyn Heights. With four bedrooms, the flexibility to create a fifth, a dedicated office, and three full baths, the home combines the generous proportions and versatility of a townhouse with the ease of apartment living. Fifteen windows fill the oversized rooms with light, while thoughtful custom details and elegant finishes create an atmosphere that is both sophisticated and inviting. The main level opens with a welcoming foyer featuring two large closets and flows into an expansive living and dining space. The windowed eat-in kitchen is appointed with top-of-the-line appliances, including a Sub-Zero refrigerator, paneled dishwasher, wine refrigerator, and a Bertazzoni induction range. The kitchen connects seamlessly to the living and dining room, where a coffered ceiling and custom built-ins add warmth and character. A generously sized bedroom and full bath complete this level. Upstairs, the oversized south-facing primary bedroom connects directly to a dedicated office, creating a spacious and versatile private retreat. Two additional bedrooms, two full baths, and a separate windowed play area—easily configured as a fifth bedroom—complete the upper level. Custom closets throughout provide abundant, thoughtfully integrated storage. The apartment was thoughtfully renovated by award-winning interior designer John Willey in 2022 and has been meticulously maintained ever since. Carefully selected wallpaper, custom window treatments, bespoke built-ins, and a mix of new and recessed lighting installed create a sophisticated and cohesive aesthetic. An Electrolux washer and dryer and security and sound system add modern comfort and convenience. The location is quintessential Brooklyn Heights. The famed Brooklyn Promenade is less than half a block away, with Brooklyn Bridge Park just moments beyond. Montague Street is right around the corner, offering an excellent selection of restaurants, cafés, shops, and everyday conveniences, while acclaimed destinations including Clover Hill and The River Café are nearby. The apartment also comes with two private storage units, and residents enjoy a beautiful common garden, bike storage, and a live-in superintendent.
