One of the Upper West Side’s most historic estates, the famed Kleeberg Residence offers gilded age opulence overlooking Riverside Park with Hudson Bay sunset views. Built in the 19th century and lovingly restored, this nearly 11,000-square-foot French Renaissance Revival mansion on a 37-foot wide lot features 18 rooms, four terraces, eight bedrooms (including a two-bedroom suite), nine and one half bathrooms, and nine gaslit fireplaces. Designed by society architect Charles Pierrepont H. Gilbert, classic gothic details adorn the exterior while modern amenities, including a sleek cobalt-blue-accented kitchen, spa area with gym, expansive master suite with marble-clad bath and walk-in closet, as well as a sublime indoor resistance pool, celebrate the best of Manhattan living.
