Description

Two corners, three exposures and wide-open city views. Completely reimagined by its architect owners, this three-bedroom, three-and-a-half-bath home brings bespoke interiors to a panorama of Manhattan rooftops, the Empire State Building and Hudson Yards. Custom millwork, Calacatta marble and other stone finishes give the interiors texture and depth, complemented by sophisticated lighting throughout. The kitchen pairs Miele appliances with a custom breakfast banquette. A built-in bar and coffee station, complete with Sub-Zero wine refrigeration, carry the home from quiet mornings to evenings with friends. A glass partition allows the living and dining spaces to open together for entertaining or close apart for work and conversation, preserving light and sightlines between them. The transformation extends to a reconfigured foyer, an expanded primary walk-in closet and a redesigned, windowed primary bath featuring a Victoria + Albert vanity and TOTO Neorest toilet. The primary bedroom occupies the northeast corner, while both secondary bedrooms enjoy open northern views. A separate laundry room includes an LG washer and vented dryer. Set within the award-winning 35XV, with its striking, sloping glass facade, the home enjoys access to private wine storage, a state-of-the-art fitness center, billiards room, residents' lounge, children's play area and a shared outdoor terrace. Maintenance includes a special assessment of $648.60.
