Gary Barnett is making moves in Midtown


Jan 30, 2026
By Holden Walter-Warner

Gary Barnett is having a moment in Midtown, and it’s not just about new construction.

Within days, the Extell Development founder popped up on two very different fronts: quietly locking up one of the most consequential development assemblages on Park Avenue and winning a court ruling that clears the way for him to potentially take control of a deeply distressed office tower owned by rivals SL Green and RXR.

Together, the moves underscore Barnett’s playbook in a market still working through pain: lean into prime locations, exploit dislocation and don’t shy away from conflict.

On the growth side, Barnett is in contract to buy 405-415 Park Avenue, air rights from Central Synagogue and is negotiating for the adjacent office building at 110 East 55th Street, according to people familiar with the deal.

Sellers were shopping the pieces for north of $500 million, The Promote first reported, and the combined site could support roughly 700,000 square feet with additional air rights. The assemblage sits just steps from JPMorgan Chase’s new 270 Park headquarters and near Citadel and Vornado’s planned 350 Park tower, placing it squarely in the corridor where trophy office capital is concentrated.

At the same time, Barnett is pressing his advantage on the other end of the market. A state Supreme Court judge this week denied SL Green and RXR’s attempt to block a UCC foreclosure auction tied to Worldwide Plaza, clearing the way for Extell to move forward after quietly acquiring the senior mezzanine debt.

…. Taken together, the Park Avenue assemblage and the Worldwide Plaza fight show Barnett operating on two tracks at once — assembling blue-chip dirt for the next cycle while using debt to pry opportunities out of this one.

I’m really interested in 400-410 Park. Since it appeared on SLG’s schematic, I hope that they have a role in that site.

More reasons for new construction.

Park Avenue’s office market is tight — and getting tighter.

At Vornado Realty Trust and SL Green’s 280 Park Avenue, financial firms Elliott Investment Management, Wells Fargo and PJT Partner inked deals for a total of 90,000 square feet in the last three months, leaving a mere 19,000 square feet of available space.

That’s just one example of the corridor’s limited inventory. Project management firm Turner & Townsend signed a lease in February for 24,000 square feet at SL Green’s 100 Park Avenue, bringing the 36-story tower to full occupancy. Southern Land Company’s 13,000-square-foot lease at Global Holdings’ 99 Park Avenue last summer brought the Class A tower to capacity.

“If you want large blocks, they just don’t exist,” said JLL’s Joe Messina, crediting financial and legal firms with gobbling up much of the space. “Some clients say that being on the avenue itself is an amenity because of the proximity to the people that you’re doing business with, you’re rubbing shoulders with it, you’re grabbing lunch with and you pass on the street.”

With large blocks increasingly scarce, tenants are getting creative by stitching together space across multiple buildings. Investment firm Carlyle did just that, signing leases for more than 200,000 square feet across two Park Avenue towers after outgrowing its headquarters at One Vanderbilt.

“As long as I’ve been in New York, I have not seen that many tenants evaluate that as a real long-term strategic occupancy opportunity,” King said. “That’s just indicative of the fact that Park Avenue just doesn’t have significant space available.”

JP Morgan Chase’s massive investment in its gleaming new headquarters at 270 Park Avenue and several nearby buildings has also created buzz around the corridor, and forced its competitors to rethink their own office strategies. For tenants unable to secure blocks on Park, alternatives on adjacent corridors have become increasingly attractive. Lexington and Sixth Avenue have seen a surge of leasing, while Madison Avenue and even Third Avenue are benefiting from the overflow.

With no new construction delivering until at least 2029, Park Avenue’s tight market is expected to persist. The trend mirrors the broader bullish streak in New York’s office market, with financial firms at the forefront.

“We’re coming off arguably the best leasing year that New York has had holistically, but it all started by financial services in the Midtown core, particularly on Park,” King said.

Thanks.

Hopefully, the redevelopment of 400 Park is more than mere speculation. HappySlap thinks it is.

I hope that Extell builds something impressive here.

For my money, Extell is one of the greatest things to happen to this City in the 21st century.

One57 and Central Park Tower were nice appetizers.

Then he has at least 4 more supertalls and a hulking office tower on 5th under development at the same time.

He cleaned up the diamond district with the Gem Tower and the new Kimpton.

He brought a near supertall to the LES.

And he gets stuff done. When Extell is in charge, there is no doubt it's getting done in a timely fashion.

[ChiND]

Even if he acquires the adjacent parcels, it’s still a small site. Maybe it will be a mixed use tower. Although he’s building condos at ABC and 650 Madison, there’s huge demand, and Extell can get this out of the ground before the other two.

Gary Barnett Buys Friars Club Building for $19M

That's a beautiful building. I'd hate to see it razed. However, I wonder if Gary owns the 1950s eyesore just to the west of it and has a new project on the horizon. It would really be a coup if he acquired the building on the northeast corner of 55th and Madison. That would be a very prime site!

[Crawford]

It's landmarked, so can't be razed. I wonder if Extell is planning an assemblage fronting on Madison.

I don't think this is necessarily connected to his Park Ave. blockfront. This could be a separate thread/project.

That's good. Gary must have a plan up his sleeve. A new tower on Madison would be nice.

Could possibly be a lands wap with one of the properties he is trying to buy for the Park Avenue project.

What is Gary Barnett’s secret plan for the Friars Club?
Extell acquisition leads to speculation about what Barnett will do with the shuttered club

Historic Midtown hangout the Friars Club found a surprising buyer: Gary Barnett’s Extell Development.

The six-story club on 57 East 55th Street went into contract with Extell for $19 million, The Commercial Observer reported and sources told The Real Deal. Kairos Investment Management sold the club, which once counted A-listers like Johnny Carson, Jimmy Fallon and Joan Rivers as members.

Extell was under contract to acquire 407–417 Park Avenue and 405 Park Avenue. Barnett has also been in talks to acquire an adjacent office building at 110 East 55th Street. Extell could build 527,000 square feet of development as-of-right on the Park Avenue properties, or up to 700,000 square feet of rentable office space with additional air rights, according to marketing materials.

Industry speculation is that Barnett strategically acquired the Friars Club to add something to his assemblage. It’s not obvious what that something is.

The Friars Club’s location is across the street from the parts of Barnett’s other proposed acquisitions. Barnett has been narrowly focused on buying up a corridor around 54th and 55th Street, on the same block as Central Synagogue. The Friars Club, however, sits across Park Avenue and one block up 55th, closer to Madison Avenue.

[NYguy]

This is the part I’ve been speculating about…

The third option is the most intriguing. The Promote previously reported Barnett could be looking to acquire the 54th Street property that houses The Brook, a secretive and elite private club. The Brook is adjacent to 405 Park Avenue, a site Barnett is under contract for.

The Brook, whose members reportedly included Fred Astaire and John Jacob Astor, would likely need to be acquired by Extell in order for the developer to construct its next high-rise.

The Brook resides in a century-old building at 111 E 54th Street. The five-story building’s size is similar to that of the Friars Club. Yet, the Friars Club is noted for the beauty of its interior, including its curved wood staircases and stained glass windows.

The Promote speculated that Barnett could offer The Friars Club as a new home for The Brook.

The 14,541-square-foot interior of the Friars Club is not landmarked, allowing the new owner to remodel the space. And for $19 million, Barnett would get a steal at the returns he yields from the Park Avenue mega-development he seeks.

[ChiND]

That seems likely.

Gary Barnett buys Park Avenue dev site for $500M
Deal locks in biggest piece of massive Midtown assemblage Gary Barnett sealed the deal on the biggest piece of his sprawling Midtown assemblage.

Barnett’s Extell Development closed on the development site at 405-417 Park Avenue for $500 million, sources familiar with the deal said. Barnett also purchased air rights from nearby Central Synagogue for $20 million and may be looking to buy at least two adjacent buildings to piece together an even bigger footprint.

The properties traded span the full blockfront between East 54th and East 55th streets. They were owned by two separate ownership groups: Swedish investor Corem Property Group AB sold 417 Park Avenue to Extell, while German asset manager DWS sold 405 Park Avenue. Both sellers and Barnett declined to comment.

The assemblage can support roughly 527,000 square feet of development as-of-right, or up to 700,000 square feet of rentable office space with additional air rights, according to marketing materials from Newmark, whose Adam Spies, Marcella Fasulo and Adam Doneger brokered the deal. CBRE’s Steve Siegel and a Fried Frank team advised on the air rights deal.

The developer is also in the process of acquiring the adjacent office building at 110 East 55th Street, according to sources. It’s unclear where those negotiations stand, though tenants in the building have been told to vacate by December, one source said. The property is owned by the Parkoff Organization. Adam Parkoff did not immediately respond to a request for comment.


Barnett may also have his sights on 111 East 54th Street, home to the private club The Brook. He has plans to buy that building and relocate the storied club to the former Friars Club building at 57 East 55th Street, which Extell recently purchased for $19 million, a source said. But a longtime doorman who answered the phone at The Brook on Friday said the building is not for sale and the club is not going anywhere.

Barnett’s site sits steps from JPMorgan Chase’s new 2.5 million-square-foot headquarters at 270 Park Avenue and near Citadel and Vornado Realty Trust’s planned tower at 350 Park Avenue, placing him in the center of Midtown’s next wave of trophy office towers.

The acquisition marks another major Midtown bet for Barnett, who has spent years amassing land and air rights across the Plaza District. While the ultimate plans for the site remain unclear, the scale and location suggest a premium office or mixed-use tower designed to compete with the corridor’s newest supertalls.

Extell is also developing a 29-story office and retail tower at 570 Fifth Avenue between West 46th and 47th streets and is building a residential supertall at 655 Madison Avenue.

I'm sure this will be another spectacular development on prime Park Avenue space.
