The embodiment of distinguished Upper East Side elegance, this incredible full floor, four bedroom, five and a half bathroom home was impeccably designed and masterfully executed by renowned architect R.M. Stern. Boasting exceptional custom finishes and fixtures, no detail has been left unconsidered, nor expense spared in this sprawling 4,613 sq.ft residence. Stepping off the key-fobbed elevator into a private foyer, you are welcomed into the contemporary, stylish gallery. Natural light floods the expansive dining room through massive floor-to-ceiling windows and under soaring 11-foot ceilings. The adjacent living room looks east and south with sweeping city views through huge bay windows and is crowned by a bespoke media cabinet framed in ebony marble and sueded paneling. Sunlight floods the custom, eat-in Christopher Peacock-designed chefs kitchen, which boasts a large Calacatta marble-topped kitchen island and a custom-built breakfast banquette, as well as the finest appliances from SubZero, Wolf and Miele and features marble-topped counters, a separate wet bar and two walk-in pantries. Select cut walnut-stained oak herringbone flooring underfoot and a chic, gilded powder room with marble inlay round out the offerings of the common spaces. Sitting in the separate north wing, the handsome and intimate palatial primary bedroom suite features floor to ceiling windows facing north and east, in addition to customized, discreet closets, a walk-in closet, and two marble-clad ensuite bathrooms - one with a soaking tub and separate glassed-in shower, and the other with an oversized rain shower. Two more light-filled bedrooms feature en suite bathrooms and ample storage space . A plush, large fourth bedroom with customized Burled Walnut shelving and an en suite bathroom sits off of the living room and can easily be used as an office. Creston AV and Lutron lighting is wired throughout the home, and a laundry room with Electrolux washer/dryer sits tucked along the corridor of the bedroom suites. 520 Park Avenue is a full-service boutique condominium with a 24-hour doorman, and 35 private, full-floor residences.
