About four years ago, New York real estate agent Jessica C. Campbell brought together a star-studded team of architect Eric Sheffield, interior designer Paris Forino and ink Construction to convert one of her clients’ residences—a five-bedroom pied-à-terre on the sixth floor of Manhattan’s Porter House luxury condo building—into Residence 6 (66ninthave6thfloor.com). What emerged is a chic, one-of-a-kind dream home chock-full of bespoke designer furnishings, accessories and midcentury modern treasures now on the market for $26.96 million.

“We wanted this residence to stand out,” says listing agent Campbell of Nest Seekers International. “Materials, craftsmanship and design were taken to an unprecedented level—from the moment one crosses the threshold, you know you are walking into something very special and not like anything else on the market today. Every square inch is more beautiful than the next and perfectly executed.”

Situated at 66 Ninth Ave. in the Meatpacking District, the exclusive abode features 5,000-plus square feet of timeless yet contemporary living space spanning the entire sixth floor. Among the showstopping details: a keyed elevator that opens to reveal a 200-pound front door (made with a rose mirror, gunmetal steel and hand-burnished brass at a cost of about $40,000); a massive gourmet kitchen equipped with a 399-pound solid cast-bronze sink crafted by Rocky Mountain Hardware (along with Gaggenau and Sub-Zero appliances); and a grand salon that leads to a 120-square-foot terrace offering breathtaking views of the city.

Also over the top is a lavish wet bar featuring a duo of solid brass custom shelves

and bleached walnut millwork that serves as the centerpiece of the warm and cozy den, as well as a sumptuous southern-facing master retreat sporting floor-to-ceiling windows; dual, spalike baths (one with a Kaldewei cast-iron tub and separate glass-encased shower, and the other outfitted with a walk-in steam shower); and custom dual showroom-inspired closets by Italy’s Porro Furniture. Adding to the property’s enticing appeal? A cutting-edge Savant home-automation system, and specially designed windows that render the surroundings pin-drop quiet via 11 layers of glass and gel.

“Residence 6 is a masterpiece—a work of art in every detail, in every square inch,” says Campbell. “It’s the new definition of an ultraluxurious, tailor-made private residence, just waiting to be discovered, adored and acquired by one lucky buyer.”
