Amazon may be landing in yet another Amazon Alley building.

Paperwork has been drafted for the Jeff Bezos-owned company to lease the rest of SL Green’s 460 W. 34th St. — some 400,000 square feet, sources said.

In April, Republic Bank signed a lease to take 211,521 square feet starting in April 2021 on the ground, mezzanine and floors two to six. It will include two bank branches.

According to CoStar data, 224,471 square feet remain on the seventh through 12th floors and another 186,641 square feet on the 14th through 20th floors.

There is no 13th floor in the 638,000-square-foot industrial building, which was previously known as the Master Printers Building.

The building sits on the entire 10th Avenue blockfront between West 33rd and 34th streets opposite Hudson Yards.

Its current brass and marble lobby will be moved to West 33rd Street, where a modern, glass-boxed lobby will be installed. The old façade will be recolored a gray tone, while some 9-foot-high industrial-style windows, elevators and double-height storefronts will be created. Additionally, an amenity important to tenants, a new 5,000-square-foot roof-deck, will include a 3,000-square-foot lounge.

Brian Waterman, Scott Klau, and Erik Harris of Newmark Knight Frank represented SL Green, and both companies declined to comment. Amazon did not immediately respond.

Keep in mind, this is a draft lease, nothing is set in stone, and big tech companies have been notoriously flaky — looking at everything and jumping from one project to another as building owners ply them with goodies. Amazon, of course, broke up with Long Island City on Valentine’s Day.

Amazon already has roughly 1.6 million square feet along the West 34th Street corridor and is teeing up to take another 800,000 to 1 million square feet in the area.

The additional space could end up at Brookfield’s Manhattan West, any Hudson Yards project, Vornado’s Farley Building or the quietly offered Tishman Speyer Morgan Post Office redevelopment that will also have a huge and gorgeous roof-deck.

Meanwhile, as Crain’s reported, Related appears to have lured Facebook to as many as 1.8 million square feet at 50 Hudson Yards, but would move into 55 and 30 Hudson Yards while 50 is being erected.

According to CBRE, tech talent in the Big Apple metro area grew by 4% in 2018, to 264,000 jobs, and 44% since 2011.
