Welcome to one of the truest Penthouses in downtown Manhattan, the pinnacle of the condominium at the General Theological Seminary. Situated atop a boutique, 20-residence building, and occupying the entire top floors, the penthouse is a story of scale, space, privacy, light, and charm. It spans nearly 4,000 square feet inside with more than 900 square feet of highly usable terrace space across two terraces. And, as it sits above the landmarked townhomes of 20th Street and exposes into the private, tree-filled courtyard of the seminary, light abounds. The home was fully built by the current owners with the help of Alan Wanzenberg and Lewis Miller, with a fully custom layout and finish palette. It now has four bedrooms, an office (or fifth bedroom), a stunning sunroom, and four full baths. Enter into a gracious foyer and spill into the large, triple-exposure living room, surrounded by a wraparound terrace. The space has a wood burning fireplace, custom millwork, impeccable herringbone flooring, and unmatched southern light. The chef's kitchen is equipped with appliances by Wolf, Miele, and a dual Sub-Zero, two dishwashers, two wine refrigerators, stunning marble countertops and custom oak cabinetry. This space is adjacent to a service corridor with full-sized venter washer/dryer and ample pantry storage. The living area flows effortlessly out onto a wraparound, planted terrace with high glass, which has a built-in Wolf grill, dining table for eight, and multiple seating areas. There is a cozy den with built-ins and custom furnishings that could operate as a fifth bedroom or television room. Three guest bedrooms are en-suite and each come with large closets that have been custom built. The exposures are exceptional: the home sits among the treetops of the Seminary, allowing for a charming, seasonal view, and lies along the rooftop pitches of the gothic-style Highline Hotel and the Seminary buildings to the north. Each en-suite bath is clad in custom marble and tiling, and has fixtures by Dornbracht. The primary suite is private and grand, and sits in the northeast wing of the home. With its own wood-burning fireplace and corner views, it is an enviable space. There is a spacious, customized dressing room, vanity area, en-suite primary bath with deep soaking tub, steam shower, heated floors, and custom tiling. Upstairs from the primary is a sunroom, used as a wet bar, massage room, home gym, or sitting area. It has floor-to-ceiling glass with exposures up to the Empire State Building and extends out to the second corner terrace, over 400 square feet and with beautiful city views. The home enjoys Lutron lighting, multi-zoned central air (separate for each room), a built-in speaker system, custom art lighting, and automatic shades throughout. Two large storage units transfer with the sale of the penthouse. 455 West 20th Street is the architectural marriage of one of the oldest buildings in Chelsea and a new, ground-up construction, atop of which this penthouse lies. Amenities include a 24-hour doorman, ground-level fitness center, bicycle storage, and access to The Close, a private outdoor space with winding paths, stone benches, and maintained landscaping-- a true urban oasis unlike anything in the city.
