CONDOP. Not a co-op. This is a favorable land lease building. Resident lounge coming soon! Currently presented via virtual renderings; scheduled for completion July 2026. The Fourth Floor at 1228 Madison Avenue is a 4-bedroom, 3.5-bath full-floor home spanning 3,136 ft (291 m), with desirable east and west exposures. A private elevator vestibule leads to a dramatic 8' white oak entry door, opening into an elegant foyer with custom-stained white oak flooring in a chevron pattern. This distinctive flooring continues through the main living spaces, culminating in a nearly 30' great room bathed in natural light from five oversized windows overlooking Madison Avenue. Adjacent to the great room and separated by pocket doors, the sunny eat-in kitchen features white matte lacquer Molteni cabinetry with white oak tambour detailing, and honed Calacatta Estremoz slab countertops, backsplash, and seating at a built-in breakfast counter. Top-tier appliances include a Lacanche 7-burner range, along with Wolf, Miele, and Sub-Zero appliances, wine refrigerator, and full-height pantry. The bedroom wing features 7" white oak plank flooring throughout. The spacious primary suite offers two oversized closets and a luxurious windowed 5-fixture bath with Bianco Oro marble slab walls and radiant-heated floors, a limed oak millwork vanity, custom medicine cabinets and lighting by Kelly Behun Studio, and Waterworks fixtures in burnished nickel. Secondary bedrooms each have en-suite baths with radiant-heated honed Calacatta marble floors, glazed white ceramic wall tiles, arched tiled surrounds, white matte lacquer vanities, and Waterworks polished nickel fixtures. The powder room makes a striking impression with honed Italian Burlesque marble slab floors and wainscot, a matching marble sink and countertop, and Waterworks burnished nickel fixtures. A brass-framed arched mirror and aged brass pendant sconce complete the design. Additional conveniences include a generous laundry room with side-by-side washer and dryer, custom millwork cabinetry with stainless steel sink, a discreet refuse room for contactless deliveries, private storage, and multi-zone heating and cooling throughout. No detail has been overlooked in this meticulously designed and thoughtfully appointed residence. 1228 Madison Avenue is a boutique 13-unit co-p with condo rules, crafted by the talented artisans at Robert A.M.
