Residence 3 is approximately 3,966 SF (368 SM) and is configured as four bedrooms plus a library/fifth bedroom. A private landing with direct access from the elevator to the gallery, with its intricate, hand-laid African St. Laurent and white polished marble slab floor, opens to the entertaining rooms to the south. Sun-filled public rooms with Parisian-like mahogany double hung weight-and-chain floor-to-ceiling windows have pretty exposures of historic townhouses on East 78th Street, one of the most picturesque blocks on the Upper East Side. Adding to the charm is an impressive chevron pattern quarter sawn oak floor, designed by Peter Pennoyer Architects, which runs throughout the 57-foot long enfilade of south-facing rooms--the library, living and dining room. Double pocket doors lead from the formal dining room to the eat-in kitchen, created by Smallbone of Devises in association with Peter Pennoyer Architects. The kitchen is well thought out, with coffered ceiling, hand-painted white oak cabinetry and specially outfitted spice, cutlery, utensil and pot drawers, all finished with black walnut interiors. Two Sub-Zero refrigerators, two Miele dishwashers, a professional Wolf range with custom-designed vented range hood plus Wolf wall oven and microwave, an adjacent walk-in pantry and an island with seating are just some of the features of this special kitchen. In the private bedroom wing, the master suite has walk-in closets and a five-fixture bath with radiant heated floors, private water closet and eight-jet steam shower with bench. The apartment has a laundry room, and five full baths and conveys with storage. Among the many details that set 151 East 78th apart are olive knuckle brass hinges and doorknobs (all custom-designed and handmade by Lowe of Maine), Lefroy Brooks bath fittings, and state-of-the art mechanicals and environmental systems, including an emergency generator, humidification system, wiring for audio, communications, data ports and the most sophisticated air conditioning and heating system available.
