Description

This exceptionally wide and lovely red brick Neo-Georgian mansion is ideally situated on one of the Upper East Side's most charming and architecturally significant townhouse blocks. The grandly scaled interiors are complimented by renowned architect Peter Marino's extraordinary taste and superb craftsmanship. A gated Entry leads to both the Front Door and a secondary Service Door. Once inside, an elegant and classic marble Gallery with an impressive staircase greets you and leads to one of two Kitchens that service this double width house. A suite of two Staff Rooms with ensuite Baths are situated beyond. There is also a huge and square 35 ft deep south facing Garden surrounded by neighboring gardens, thereby creating a verdant and unexpected oasis. Upstairs, marvelous ceiling heights and superb proportions create an artfully balanced Parlor Floor with a 30 ft wide grand Living Room with intricate period moldings and architectural detailing. Across the landing, an elegant formal Dining Room replete with a Fireplace is distinguished by four tall bay windows overlooking the superb Garden. Artfully positioned between these two rooms is a large marble clad Serving Kitchen which most efficiently works in tandem with the main Kitchen, by means of a service staircase, below to facilitate entertainment on any scale. The Master Bedroom includes a combined Bedroom and Sitting Room with a Dressing Area proceeding to a luxurious marble Bath. Adjacent is a handsome wood paneled Library with fireplace also overlooking the Garden. The fourth floor is comprised of three large Bedrooms and two Baths. Completing the layout, the spacious windowed basement includes a gym and extensive storage space. Both impressive in size and architecturally significant, this house is ideal for sophisticated living and big entertaining. Moreover, a buyer is offered an extraordinary opportunity to acquire one of the most lovely and optimally situated mansion town houses in Manhattan.

Building Information

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
