With 16-foot ceilings and soaring arched windows overlooking Union Square Park, this home offers scale, light, and drama that are simply unmatched. The expansive living and dining space flows into a custom chef’s kitchen with professional-grade appliances, marble island, and bespoke finishes—perfect for both entertaining and everyday living. Each bedroom features an en-suite bath with refined stone and wood finishes, while a powder room and full laundry room add convenience.
