Mighty Amazon may have found a new home in the asphalt jungle. The online marketing gorilla has been trolling the city for a uniquely large office where it can expand by leaps and drones.

We’ve now learned that it is negotiating for a Midtown perch at the Durst Organization’s 1133 Ave. of the Americas at West 44th Street.

The 285,872 square-foot block on the second through 10th floors will be vacated by the Internal Revenue Service. E-mails asking where it was moving went missing.

Durst’s marketing flyers for the floors describe the ability to create a “distinctive presence as an anchor tenant on the exterior of the building as well as in the lobby.”

It will include “a private entrance with a generous plaza area” on West 44th Street and a sprawling 13,000 feet of outdoor landscaped terraces on the second floor, where CEO Jeff Bezos will have views of Bryant Park while he tests out drone deliveries — perhaps to rooftops in the Diamond District.

After the company’s search was outed in 2012, Amazon’s brokers, Justin Halpern and Marcus Rayner of CRESA Partners, securely zip-locked other brokers from yakking, leading some to wonder if they were even still in the market.

The company now has 92,492 feet at the nearby 1350 Ave. of the Americas. But the requirement was difficult, as the retailer expects to gobble up 100,000 to 200,000 feet every few years.

The Durst Organization, led by cousins Jody and Douglas Durst with Tom Bow as their leasing honcho, also has large vacancies at One World Trade Center and 4 Times Square But they are also known for their flexibility and cutting creative deals like that needed by Amazon.

Those who accidently lifted their phones declined comment, but stay tuned.

In other big-but-not-quite-done deal news, Bank of Tokyo/Mitsubishi is in the midst of leasing about 303,112 square feet at the base of the McGraw Hill building at 1221 Ave. of the Americas. The former Société Générale space on the sixth through 10th floors is now vacant and CoStar data shows an asking rent of $75 per foot.

The bank is currently located in 1251 Ave. of the Americas, and sources said will move in from sites that include 1633 Broadway.

Fred Smith of Cushman & Wakefield is representing the tenant, while a C&W group that includes John Cefaly, Gus Field, Rob Lowe, Michael Burgio, David-Jonathan Fales and David Berke is representing the building. Ed Guiltinan of the Rockefeller Group worked in-house for the ownership that includes the Canadian Pension Plan Investment Board.

When this deal is completed, more than 1 million square feet will have been leased over the past year in this 2.5 million-foot tower.

Neither C&W nor the Rockefeller Group would comment on a possible pact.

One pact that did take place, however, was the wedding of David Berke to Kelli Mekles, both of Cushman & Wakefield, on June 28 at Tribeca 360. Congrats to this adorable couple.

The new Mrs. Berke, who is the current vice chairman of the Young Men’s/Women’s Real Estate Association (YM/WREA), missed its annual kayaking expedition on the East River this past Friday with the Long Island City Boathouse. A wet and wild time was had by all.

Estee Lauder’s Aveda division will give up some of its valuable, sprawling ground-floor space at One Soho Sq. in its 233 Spring St. building and move its institute right above it to 20,000 feet on the second floor.

A direct connection will bring visitors from a reconstituted 1,500-foot retail space to its new duplex installation, which has 13-foot high ceilings and views of the triangular Soho Square Park.

Aveda used Ed Velten, in-house at Estee Lauder to negotiate the deal, while Josh Kuriloff, Jonathan Fales, Jodi Roberts, Jamie Katcher and and Matthias Li of Cushman & Wakefield represented the Stellar Management-led ownership in this transaction. No one returned calls for comment.

Funny girl Ellen DeGeneres and design guru J. Christopher Burch have found offices for their new joint design venture, ED. The 5,186 feet encompasses the entire 11th floor of the 12-story 121 E. 24th St.

Jeff Buslik and Brad Cohn of Adams & Co. repped both sides in the deal, which had an asking rent of $49 per foot.
