46 West 90th Street is a 6,790-square-foot Renaissance Revival townhouse, originally designed in 1901 by Theodore E. Thomson. Currently configured as four free-market units, the property features a renovated owner’s duplex with 3 bedrooms, 3.5 bathrooms, 2 offices, a spacious kitchen with high-end appliances, and a beautifully landscaped private backyard. Original architectural details including coffered ceilings, an original wood mantel, and a grand staircase leading to the upper rental units are standout features of this home. With the owner’s unit delivered vacant and all free market unit leases expiring in 2025, the property offers exceptional flexibility—whether used as a primary residence with income-producing rentals, an investment property, or converted to a stately single-family home. Located on a picturesque tree-lined block just steps from Central Park, 46 West 90th Street is close to top Manhattan schools, acclaimed restaurants, vibrant retail, and premier cultural institutions—capturing the essence of Upper West Side living.
