This spectacular residence is designed by one of the most celebrated architects of our time, Robert A.M. Stern. Residence 3A, with three bedrooms, three full bathrooms and a powder room, seamlessly incorporates modern finishes with traditional prewar elegance. The entry opens into an octagonal formal gallery that leads into an oversized living room complete with 11 foot ceilings and enormous East facing windows. This beautiful home enjoys custom casings and base moldings throughout. Off the gallery is situated a handsome powder room fitted with Grigio Carnico marble vanity and floors, Toto water closet and Lefroy Brooks hardware, all of which were hand selected by Mr. Stern. White Appalachian herringbone oak floors with a walnut stain graciously adorn all the public spaces, including the formal dining room. The chefs kitchen boasts custom shaker inspired millwork cabinetry, natural Brazilian quartzite countertops, Lefroy Brooks hardware, Gaggenau appliances and a center island. The master bedroom serves as a quiet reprieve with northern exposure and a luxurious walk in closet complete with a dressing table. The en suite marble master bathroom is pure sophistication with its custom designed double sink vanity and Wi Fi enabled heated flooring. Two additional bedrooms offer western exposure as well as en suite white marble bathrooms. This magnificent residence is the definition of classic elegance.
