Rare Double-Width Townhouse Opportunity
Located in Prime Upper East Side Location
33.3 ft X 102 ft Lot

Built in 1878 as a row of Neo-Grec townhouses, designed by prolific Manhattan architect John G. Prague, these two continuous townhouses offer the rare opportunity to combine two single-family townhouses into one grand residence over 33 ft wide with approximately 14,000 sqft throughout while being located in one of the best locations in the Upper East Side (between Fifth and Madison Avenue).

Currently, both townhouses are in "white-box" condition with entirely demolished interiors ready for renovation with over 33 ft wide frontage, on a 102 ft deep lot including a rear private garden, along the north side of East 77th Street between Fifth and Madison Avenues.

Provided are combination floorplans crafted by Zivkovic Connolly Architects P.C, known for their award-winning portfolio of residential, institutional, commercial, and interior design projects. This proposed floorplan envisions a grand-scale residence with approximately 14,000 sqft of interior square footage with grand spaces featuring ceiling heights up to 12ft high. These conceptual floorplans include a total of eight bedrooms, twelve bathrooms, four powder rooms, with a formal living room, dining room, and kitchen with a breakfast area, two staff suites, an exercise/gym room, home theater, wine cellar, mudroom, roof terrace, and sunroom all perfectly connected by a beautiful wide center staircase with a skylight above.

Renderings and Floorplans are for visualization/conceptual purposes only; please consult with your architect/expeditor for additional information and required approvals
