Welcome to Unit 222 at the 400 building, a landmarked Modernist masterpiece by Edward Durell Stone overlooking the Atlantic ocean and beach. This sun-filled south-facing duplex blends timeless architecture with modern updates: clean lines, custom millwork, and refreshed kitchen and baths. Dramatic 10' living room windows flood the entertaining level with light, opening up to a terrace. Upstairs, you have partial ocean views in the spacious primary suite with a marble bath, built-ins and washer/dryer. The second bedroom is a guest retreat with a bath ensuite. Life at the 400 building is unmatched...a rooftop pool, patio with ocean views, and a workout gym. Located a block from Worth Avenue and a short walk to restaurants and shopping. Unit 222 is Palm Beach perfection!
