Experience the best of Upper West Side living in this expansive and totally renovated duplex, spanning over 4,400 square feet. Boasting five bedrooms and four-and-a-half baths, this chic residence offers a rare combination of contemporary living in a prewar space. This beautiful condominium home enjoys not only top-of-the-line finishes and 10-foot ceilings throughout, but also a convenient separation of private and public spaces. The custom-made Smallbone of Devizes open-plan chef's kitchen incorporates cabinetry in a white, hand-painted finish, accompanied with glass-fronted upper cabinets and antique brass hardware designed by Architectural Digest "AD 100" designer, Stephen Sills. An array of Miele appliances including wine refrigerator and White Carrara honed marble countertops with full-height slab backsplash complete this elegant but highly practical kitchen. Solid oak herringbone floors grace the public rooms, with plank floors found in the kitchen, bedrooms and corridors. Eastward exposure in the living room and den (formerly a formal dining room) provide one-of-a-kind views of the American Museum of Natural History. The gas fireplace adds warmth and focus to this large room. The main floor also offers an elegant powder room for guests and a large playroom, which could easily be converted into a private home gym. Bathrooms feature sinks, fittings, and accessories from Waterworks and Stephen Sills custom-designed millwork. The luxurious primary suite is a serene retreat with generous closet space and a spa-like, five fixture ensuite bathroom. This bedroom enjoys corner exposure, with light streaming in from the west and south. Off the primary bedroom is a laundry closet, and a windowed home office with ensuite bathroom. This can be turned into a fifth bedroom if needed. The second floor of this spacious home features three additional bedrooms and two more bathrooms. The bathrooms are beautifully renovated to the standards of the rest of this home. Designed by Emile Gruwe and completed in 1886, 101 West 78th Street is a landmark building at the corner of 78th Street and Columbus Avenue, directly across the street from its architectural contemporary, the American Museum of Natural History. This turn-of-the-century treasure has been thoughtfully restored and thoroughly modernized to preserve the historical fabric of the building and create an elegant, modern boutique condominium for the 21st century. Stephen Sills has fashioned the building's lobby, and there is a 24-hour doorman, gym, playroom, and individual storage cages. 101 West 78th street is just moments from all the best the Upper West Side has to offer, including Central Park, Citarella, Fairway, Trader Joe's, Lincoln Center and more.
