Impeccably designed and masterfully executed by renowned architect R.M. Stern and Molori Design, this spectacular full floor, four bedroom, five and a half bathroom is the epitome of elegant Upper East Side living.  Sprawling over 4,613 square feet, this outstanding residence boasts the finest custom finishes and fixtures, with no detail unconsidered, nor expense spared.

Stepping off the key-fobbed elevator into a private foyer, you are welcomed into the grand, sophisticated gallery.  Natural light floods the expansive dining room through massive floor-to-ceiling windows under soaring 11-foot ceilings. The adjacent living room looks east and south with sweeping city views through huge bay windows.

The custom, eat-in Christopher Peacock-designed chef's kitchen boasts the finest appliances from SubZero, Wolf and Miele and features [marble] topped counters, a separate wet bar and walk-in pantry.  Select-cut, solid white oak herringbone flooring underfoot and a discreet powder room with marble inlay round out the offerings of the entertaining space.

Intimate and serene, the private quarters sit in a separate north wing.  The palatial primary bedroom suite features floor to ceiling windows facing north and east, a sizable custom 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 large fourth bedroom with custom-built shelving and an en suite bathroom sits off of the living room and can be used as an office or den. A laundry room with Electrolux washer/dryer sits tucked along the corridor of the bedroom suites.
