This enchanting duplex is notably one of the very few residences in the United States designed by renowned Belgian designer, Axel Vervoordt. This exquisitely renovated apartment has been crafted to the highest standards and features lyme plaster and paint meticulously applied by European artisans under Mr. Vervoordts direction. The apartment is further defined by delightfully oversized windows with sweeping views of Park Avenue from every major room, ample southern and western sunlight, ceilings that soar to over 10 feet in height, and five fireplaces. A semi-private elevator landing opens to the gracious Gallery, anchored by an elegantly curving staircase. The impressive corner Living Room, Dining Room, and Library are arranged in a seamless enfilade, all with expansive Park Avenue outlooks. The Living and Dining Rooms both have imported 18th-century parquet de Versailles floors, and all three feature gas fireplaces. Nearby, a sleek chefs kitchen features custom stainless-steel cabinets and countertops. From the Gallery a coat closet and a Powder Room are conveniently accessible. The Upper Level, private and luxurious, boasts a generous corner Primary Bedroom clad entirely in goatskin parchment leather and is bathed throughout the day with southern and western sunlight. The adjacent spa-like bathroom is outfitted with double sinks, a separate shower, and a soaking tub. Two additional Bedrooms, each feature their own fireplaces (one is currently concealed but can easily be restored to its original form, should the new owner desire). Additionally, there are two full bathrooms, a laundry room, and very ample closets. The Lancashire is a Neo-Renaissance masterpiece, built in 1910 by architect Walter B. Chambers. This coveted, white-glove cooperative incorporates only 18 residences and offers unmatched privacy and service. Rich in history and architectural integrity and featuring an exceptional and glorious design aesthetic, this magnificent residence is splendid in every way.
