Description
Recently gut renovated to an exceptional standard by renowned architect Deborah Berke, founder of TenBerke, this extraordinary 25.5-foot-wide single-family townhouse seamlessly blends timeless Brooklyn Heights charm with sophisticated contemporary design. A grand stoop flanked by two gas lanterns leads to an elegant parlor level featuring soaring ceilings, two expansive living rooms, ventless fireplaces, a powder room, and dramatic floor-to-ceiling windows that fill the home with natural light. The garden level is designed for both entertaining and everyday living, offering a formal dining room, a spectacular eat-in chef's kitchen with a Lacanche range and top-of-the-line appliances, and direct access to a beautifully landscaped private garden. The third floor is dedicated to a luxurious primary suite with a spa-like en-suite bath and walk-in closet, complemented by a home office or additional bedroom. Two generously proportioned bedrooms, two full baths, and a laundry room occupy the fourth floor. Above, the fifth floor offers a flexible living or media room with a wet bar, full bath, and a spacious terrace. Crowning the home is an incredible rooftop terrace showcasing sweeping views of the Manhattan skyline, Downtown Brooklyn, and the Brooklyn Bridge. The finished cellar is equally impressive, featuring a fully equipped gym, steam shower, sauna, wine room, and abundant storage. Perfectly positioned on one of Brooklyn Heights' most picturesque tree-lined blocks, this exceptional residence is just minutes from Manhattan by car or subway.
