This magnificent 6-story Upper West Side townhouse with a large private garden, terraces, rooftop gym & full basement is brimming with beauty & history. Built circa 1900 by architect Theodore E. Thomson, the Renaissance Revival-style home was restored & gut renovated in 2008, transformed into a stunning single-family reinvented with modern amenities. From stripping down to bare walls and reconstructing with steel & concrete, to finishing/expanding the cellar, to adding state-of-the-art features like an elevator to all levels, no detail was overlooked. The elegant transitional-style interior boasts over 9,000 sf of meticulously designed & appointed living space. Rich mahogany stairs, hardwood floors, raised panel wainscoting, tasteful crown moldings, millwork & built-ins, coffered ceilings & other classic details reflect the original period & lend exceptional character. Charm is met by contemporary systems that heighten the luxury experience, with one-touch home automation including Mitsubishi HVAC, radiant floor heating, Lutron lighting & high-tech Crestron security with thumb-printing & video surveillance. This jewel of a home with 5 bedrooms, 7 full & 4 half designer baths is bathed in light & perfect for every need: entertaining or comfortable living. The sophisticated parlor floor is a host's dream with airy living & dining rooms + a lovely loggia. The garden level extends the living space with a family room, office, sleek chef's kitchen & breakfast room leading out to the enchanting garden. Gracing level 3 is the luxurious master retreat with dressing room & spa bath, along with a stately library. Four more bedroom suites with walk-in closets & 2 terraces occupy 4 & 5. Use the top-floor gym then relax on penthouse terraces. The lower level is a haven for recreation w/laundry, full & half baths + loads of storage. Incredible living in a premier locale!
