This full-floor 4 bedroom residence spans 3,194 square feet and embodies the refined, nature-inspired design of COOKFOX Architects. Offered as a resale, it presents a unique opportunity to acquire one of the building’s most sought-after layouts, complete with 222 square feet of planted, irrigated outdoor loggias. A private elevator opens directly into a gracious entry gallery, leading to a dramatic corner living and dining room framed by floor-to-ceiling windows with sweeping 360-degree views. The corner kitchen, surrounded by four oversized windows, is beautifully appointed with custom oak, lacquer, and ribbed glass cabinetry with brass detailing, Calacatta Lincoln marble counters and backsplashes, a large island, and a pantry, alongside a suite of premium appliances.

The residence features four well-proportioned bedrooms and four luxurious bathrooms, including a serene corner primary suite positioned along the east and north exposures. This private retreat is complete with a large walk-in closet, windowed dressing room, and a five-fixture spa bath outfitted with a custom vanity, heated marble floors, a six-foot Kohler soaking tub, glass-enclosed shower, and separate water closet.
