Upper East Side Opportunity: Combine Two Units into Over 1,550 Sq Ft of Living Space This is a unique chance to combine two adjacent units, 4A and 4B, to create a spacious three-bedroom, three-bath home with over 1,550 square feet of living space. While the units are currently separate, this combination offers the potential to design your dream home, complete with a south-facing private terrace overlooking serene gardens. Bring your architect or contractor to explore the possibilities of transforming these units into your perfect space. The building offers great amenities, including a roof deck, central laundry, bike room, storage, garage, and a full-time doorman with a live-in superintendent. Located near Carl Schurz Park, Central Park, and top cultural landmarks, this is your opportunity to create a custom home in one of the Upper East Side's most desirable locations.
