Brilliant redesign of the classic pre-war duplex coop by famed architect Peter Hawrylewicz showcases extensive craftsmanship and a stunning array of stones, woods, fixtures, and hardware. Gracious stairway entry separates the formal living room with a wood-burning fireplace and dining room. Gorgeous chef's kitchen with terrazzo floors, stone counters. Rift cut oak-paneled library leads to lux master with Waterworks/Ann Sachs spa bath. Refined classic elegance at its best.
