This Upper East Side townhouse is built around a skylit elliptical staircase.

On a classic tree-lined block, this 1899 brick and limestone townhouse was meticulously renovated in 2023 to blend original character with modern ease. A gracious foyer flows to a marble gallery and the skylit elliptical stair, with an elevator for easy vertical circulation. The parlor floor impresses with ceilings over 11 feet, herringbone parquet, and wood-burning fireplaces. The eat-in chef's kitchen brings marble countertops, extensive custom cabinetry, and a fireplace, opening to a landscaped bluestone garden with irrigation and a built-in barbecue. A custom library by Dakota Jackson adds a wet bar and zebrawood. The entire third floor is a private retreat: primary bedroom with fireplace, a fully outfitted dressing room, a spa-like marble bath, and a private gym. Upper floors add four en-suite bedrooms, a terrace, expansive dressing areas, and a dramatic skylight that pours light through the home. A landscaped roof terrace with mature plantings and an auxiliary kitchen crowns it, with a lower-level media room, bar, wine storage, laundry, and updated systems including a new roof, multi-zone AC, and advanced security and media.
