Historic Cast Iron Building in New York Is Turned Into Stunning ‘Architectural Gem’ That Is Causing a Serious Stir With Wealthy Buyers

A reimagined cast iron building in the heart of New York City's Tribeca has already become one of Manhattan's most sought-after residences—with buyers snapping up almost every unit inside the property before construction had even been completed.

32 Walker Street is a seven-story, five-unit property that blends historic architecture with modern luxury, courtesy of an extensive overhaul that, when completed, will see a once-crumbling street corner transformed into a hot spot of design excellence.

But while construction on the luxury residence—which combines an existing L-shaped structure with a newly built property—is ongoing, Serhant listing agent and "Owning Manhattan" star Peter Zaitzeff, who is representing all of the units, notes that interest in the finished result has already reached fever pitch.

Of the five units that will be available, three have already sold in off-market deals, while the remaining two—one priced at $11.49 million and the other, a penthouse, listed for $17.99 million—are already attracting significant interest.

According to Zaitzeff, the quick sale of the units comes down to just a few factors that help to make the building such a standout.

"There’s a bunch of things that are really special to the building. First of all, the original building was L-shaped, it’s a cast iron building, old-school Tribeca loft," Zaitzeff explained to Realtor.com®.

The buildings designers, SOMA Architecture and The Turett Collaborative, worked with the Landmarks Preservation Commission to create a concept that would marry the original architecture of the existing building with the luxurious new structure.

“We were able to get through Landmarks to reconfigure that building and merge it into the old building,” Zaitzeff said, noting that the project offers “the best of both worlds” by pairing “old-school cast iron arched windows” with “brand new” living spaces featuring “huge French doors.”

The result is a product that stands apart in a market where space is increasingly scarce.

“If you’ve followed real estate for the past 20 years, land has become smaller, smaller, and more and more hard to get,” the Netflix star revealed.

Zaitzeff explained that developers are often forced to “fit more things into smaller apartments,” leading to compromises in storage and layout—even in high-end homes.

By contrast, the residences at 32 Walker emphasize proportion and livability, including the two remaining units.

“We’re 3,300 square feet for technically a three-bedroom, but could be easily a four,” Zaitzeff said, describing the layouts as “gracious and livable—not spaces that were small and confined.”

Ceiling heights are dictated by the original cast-iron structure and further enhance that sense of scale.

“Our first apartment floor is 13.8 [feet]. Then 13.6. Then 12.6. So, like, really high ceiling heights that create a really gracious and grand feeling,” he noted, adding that such dimensions are “not typical of new development right now.”

One of the remaining units, which is priced at just over $11 million, comes complete with floor-to-ceiling arched windows, which allow natural light to flood inside, a chef's kitchen with a chic marble island, a powder room, and more.

The primary bathroom boasts a dual marble vanity and large soaking tub.

Meanwhile, the penthouse is the epitome of luxury thanks to its panoramic views of the NYC skyline, oversized closets, private terraces, outdoor grill and kitchen, and a separate kitchenette on the upper floor.

Those design elements have helped drive demand even without a formal sales push.

“There’s five units. We’ve sold 60% of the building—three of those units—and all of those units were sold off-market,” Zaitzeff revealed, describing a quiet, broker-driven process that took place “over what was probably the most brutal winter we’ve had in the last 10 years.”

Buyers span a range of profiles, from a pied-à-terre owner splitting time with Florida to both young and established New York families.

Meanwhile, interest in the remaining units, particularly the penthouse, is already strong.

“We’ve done a number of showings for the penthouse already, I think it will be a very young tech buyer. We do have an offer that we’re negotiating right now," he revealed.

Tribeca’s continued evolution has only strengthened that appeal.

“It’s where everything is,” Zaitzeff said, citing an influx of private clubs, restaurants, and lifestyle destinations downtown.

“Everybody wants to be where it’s cool, it’s fun, it’s hip, this is the best place to be," he added.

At the same time, rising renovation costs have made turnkey properties even more attractive.

“Construction costs have gone up close to 100%,” he explained. “Instead of spending two, three years of your life on a renovation, you can buy into a really beautiful, designed new development. What’s the most important thing for people, is time.”

That combination of convenience, design, and scarcity has made 32 Walker a standout—even among New York City’s crowded luxury pipeline.

"I’ve sold a lot of new developments; this project is probably the nicest project that I’ve ever sold, or ever gotten to be a part of," Zaitzeff admitted.
