67 Franklin Street, PH-B

Offering over 6,000 square feet of seamless indoor/outdoor living, this 5-bedroom, 5-bath penthouse with four private terraces brings breezy California-style living to the NYC skyline. Designed as a true sanctuary in the sky, the residence blends expansive interiors with lush outdoor spaces to create a rare sense of openness, tranquility, and urban luxury.

Step off your key-locked elevator into the formal entry and turn the corner to an expansive open living space with soaring 20-foot ceilings, white oak and radiant-heated limestone floors, and dramatic double-height windows framing panoramic city views. Fully retractable sliding glass walls open the interiors directly onto four private terraces spanning a combined 1,431 square feet, creating an exceptional setting for al fresco dining, entertaining, sunbathing, or an urban garden. A custom dog run adds a thoughtful convenience for pet owners.

The well-appointed kitchen features an eat-in waterfall island, custom matte white lacquer cabinetry, Bianco Oro countertops, and a suite of fully integrated Gaggenau appliances. Beyond the living area, a secluded home office with a walk-in closet and en-suite bath offers a quiet retreat, while a guest bedroom with access to an additional full bath is discreetly positioned behind the kitchen.

Upstairs, a dramatic gallery overlooking the living room leads to the primary suite, featuring two windowed walk-in closets, a private terrace, and a luxurious en-suite bath with a Corian double vanity, radiant-heated marble floors, walk-in shower, and freestanding Kaldewei soaking tub. Two additional bedrooms offer generous closet space and access to another terrace, complemented by two additional bathrooms, one with a walk-in shower and the other with a soaking tub. A full laundry room with utility sink, Miele washer, and vented dryer completes the upper level.

Originally built in 1881, The Cast Iron House was transformed by Pritzker Prize-winning architect Shigeru Ban into an intimate boutique condominium of just 13 residences. Amenities include a 24-hour doorman, state-of-the-art fitness center designed by The Wright Fit, dance and yoga studio, hydrotherapy spa, steam and sauna rooms, playroom, bicycle storage, and a Green Wall courtyard.
