Curinos, a global data intelligence firm serving the financial industry, is relocating to Marx Realty’s 10 Grand Central after signing a 14,000-square-foot lease, Commercial Observer has learned.

Curinos will move from its current office about two blocks north at 485 Lexington Avenue, though it is unclear when the move will happen.

The length of the lease was not disclosed. Asking rents at 10 Grand Central — which is now 98 percent leased, according to the landlord — ranges from $85 to $135 per square foot.

Adam Ardise and Rachel Rosenfeld from Cushman & Wakefield represented Curinos in the lease, while JLL’s Mitchell Konsker, Thomas Swartz, Carlee Palmer and Margaux Kelleher represented Marx Realty. Spokespeople for C&W and JLL did not immediately respond to CO’s requests for comment.

“The robust leasing activity at 10 Grand Central demonstrates the ongoing appeal of thoughtfully designed workplaces and white glove service that combine to give companies an elevated office experience,” Craig Deitelzweig, CEO of Marx Realty, said in a statement.

“Curinos’ decision to relocate within the Grand Central market speaks to the differentiated hospitality-infused experience we’ve created at 10 Grand Central and further strengthens the building’s exceptional tenant roster,” Deitelzweig added.

10 Grand Central is a hospitality-infused office building that offers tenants a variety of amenities, including a reservable house car for transportation, a lounge and cafe on the seventh floor, a 1930s French garden-style outdoor terrace, and a newly opened speakeasy-style restaurant called Highball Ltd.

Other tenants at 10 Grand Central include data center developer Edged, bank holding company Merchants Bancorp and research firm Green Street Advisors.

Niobrara Capital has inked a 10-year, full-floor lease at 545 Madison Ave. in Midtown.

The private equity firm signed for 11,000 square feet at the building owned by Marx Realty.

Niobrara Capital is relocating from its previous office at 345 Park Ave. because “they wanted to be in the Plaza District and fell in love with the building,” according to a spokesperson for Marx Realty.

Also known as the Baccarat Building, 545 Madison Ave. is home to the U.S. headquarters of luxury French crystal label Baccarat. In partnership with the brand, the building features Baccarat chandeliers, fixtures, barware and accessories. Other current tenants include private equity firms Millennium Partners, Snow Phipps, Kohlberg, Orangewood Capital and Vialto Group.

“The building’s warm, club-like sensibility, refined design and unmistakable Baccarat touches continue to resonate with premier firms looking for a workplace that feels elevated, elegant and distinctive,” said Marx Realty CEO Craig Deitelzweig in a statement.

Niobrara Capital will take the entire ninth floor of the 140,000-square-foot building. The asking rent was $145 per square foot, according to Marx Realty.

CJ Heitner and John Cilmi of Newmark represented Niobrara Capital on the deal. Tara Stacom, Peter Trivelas, Harry Blair and Remy Leibersohn of Cushman & Wakefield represented Marx Realty.

The property was built in 1955 and redeveloped in 2008.

YONKERS — New stores, electronics retailer and restaurants have expressed interest in leasing space in the new retail area planned for Cross County Center.

The $90 million expansion, slated for the center’s north lot, includes two new buildings totaling 58,000 square feet of retail space, along with a four-acre park, boardwalk and underground parking garage.

Prospective tenants, from an international fashion brand to an electronics retailer and restaurants, have already shown interest in the space even though construction is not expected to be completed for another 18 months, project officials said.

Craig Deitelzweig, CEO of Marx Realty that owns the center, said the vision is to create a new front door to the center, with new stores, green space and sitting areas leading to a boardwalk lined with dining places.

“We want this to be the town center,” Deitelzweig said. “Our goal is to have people who want to come to the center starting in the morning and staying all the way through the evening.”

Cross County Center expansion to create community space, drive foot traffic

Opened in 1954, the center has grown from 30 stores to more than 100 tenants spanning retail, dining, education, entertainment and hospitality. Branded as the nation’s first open-air shopping mall, Cross County Center attracts about 14 million visitors annually and is now 97% leased.

The center is home to a mix of about 83 tenants ranging from national brands to local businesses. It is anchored by Target and Macy’s, along with SUNY Westchester Yonkers and a Hyatt Place hotel. New stores have consistently been added over the years.

The expansion reflects strong demand for retail space. About 88% of the 58,000 square feet of retail space has already been accounted for, with plans being finalized for a “world-class retailer” interested in occupying an entire two-story, 44,000-square-foot-building, Deitelzweig said.

The goal is to host a diverse tenant mix to attract a broad range of customers. Most visitors come from Westchester County and New York City, with a large share made up of young adults ages 16 to 23 and families.

The center also hosts year-round events, including holiday celebrations, summer festivals, yoga and Zumba classes. The new park will create space for new events such as concerts, picnics, farmers markets and soccer games or expanding existing programs.

“I always wanted to add a new park here,” Deitelzweig said. “It’s another way for us to connect with the community. We’ll make sure this space is really activated.”

The expansion will replace a portion of the north parking lot. An underground parking garage with elevator access will be built beneath the site. Construction will be carried out in phases, with the goal of minimizing disruption to operations while maintaining access to nearby businesses.

Why does demand remain strong at Cross County Center?

While e-commerce and the pandemic have taken a toll on some Westchester malls, shuttering the former Galleria at White Plains and the former White Plains Mall, other retail centers have rebounded. Cross County Center, for example, is thriving with nearly full occupancy and strong demand for additional space.

In 2024, Westchester’s mall vacancy rate dropped to 1%, far below the national average of 8.7%, according to CoStar.

Deitelzweig said sales revenues have continued to grow, attributing Cross County Center’s success to ongoing efforts to meet evolving customer needs. Those efforts include attracting and retaining trending, high-performing tenants and reinvesting in capital improvements, including upgrades to sidewalks, landscaping, lighting and storefronts.

The center is home to the first Zara, Shake Shack and Raising Cane’s locations in Westchester, as well as one of the best-performing Target and Macy’s stores in the country, Deitelzweig said. Four additional stores are slated to open, including Coach, Crocs, Crumble Cookies and Elite Nails & Spa.

He added that the center has also benefited from younger generations’ growing preference for in-person experiences and post-pandemic hybrid work schedules.

“The way we’ve succeeded for 70 years is by understanding your customers,” Deitelzweig said. “Sometimes it’s about understanding them before they even understand what they want.”

Selective on tenants as customer preferences evolve

Businesses are drawn to Cross County Center by the high foot traffic that is largely generated through events and the spillover effect of neighboring brands, although securing a spot is competitive.

Deitelzweig said the center is selective about its tenants and continues to adapt based on store performance and a commitment to maintaining well-kept storefronts. The shift toward experiential retail has prompted tenants to lease larger spaces, with more businesses focusing on experiences.

Build-A-Bear, a toy store that opened in September, offers customers the chance to design their own stuffed animals. At the center of the store, a large wheel of plush white stuffing slowly rotates as customers bring their toys to life by choosing a shell, outfit and accessories, adding a heartbeat and even recording a personalized sound bite.

Porsha Soto, the store’s manager, said the Cross County location is the company’s sixth in New York and was drawn to the center’s strong base of family-oriented customers. She hopes the expansion will bring more foot traffic and provide a better experience.

“It’s really exciting to have this space that feels welcoming and warm,” Soto said, referring to the park.

What could come next at Cross County Center?

As the center continues to grow, both the property owner and customers see potential for future developments.

Ive Lisse, of Yonkers, who visits the center about twice a month and attends some of its events, said she enjoys stores such as Old Navy, Zara, H&M, Foot Locker and Shake & Shack and hopes to see more children’s entertainment options like Sky Zone.

That sentiment echoed Deitelzweig’s vision to add businesses that offer immersive, family-friendly experiences. He said he is also open to residential development where there is a need, provided it fits into the fabric of the center.

“Customers’ desires change constantly,” Deitelzweig said. “You always have to be mindful of what customers need.”

Just a few weeks after revered longtime PDT bartender Jeff Bell announced the opening of Kees, his new subterranean lounge at 1 Cornelia Street, the cocktail guru has revealed yet another project. In partnership with Marx Realty, Bell is opening a new speakeasy-style concept, this one complete with a hidden entrance and a “complex entry process.” Highball Ltd. is officially open for business—if you can only find it inside the office tower at 10 Grand Central.

Before we get to how you can actually get in, a bit about the space, which is carved out of the building’s 11th-floor Meeting Galleries amenity, a new 11,000-square-foot hub. The entire project is essentially an homage to Grand Central Terminal: the design draws inspiration from all things train, specifically honoring the “golden age of luxury train travel,” according to an official description. The idea is that you’ll feel as though you’re sipping a very good cocktail in the bar car of a train.

The name of the destination is also on theme—doubly so. The moniker nods both to the classic whiskey cocktail and the “highball” railroad signal, when a ball raised to the top of a pole indicated that the track ahead was clear and the running train could proceed.

Highball Ltd. is actually just one quarter of the four distinct spaces that will make up the Meeting Galleries complex, which will also include a 200-person town hall venue called the Grand Gallery, a recording studio featuring state-of-the-art technology dubbed the Podcast Gallery, and the Screening Gallery—a “plush theater with stadium seating and a 150-inch screen beneath a constellation-inspired ceiling reminiscent of Grand Central’s celestial dome.”

But back to the secrecy of it all: you’ll want to look for a red light on Third Avenue near 44th Street. That’s the hidden entrance. Step inside, hop into the freight elevator and head up to the 11th floor. Perfect cocktails await… once you find the red light, of course.
