Beautiful space is available at 733 3rd Avenue, a building in Turtle Bay. The building sets itself apart with a white marble attended lobby, wall-to-wall windows and high-rise architecture. 733 3rd Avenue, also known as the Diamond National Building, was constructed in 1961. It stands 24 floors high.733 3rd Avenue is located in Turtle Bay, a neighborhood known for beautiful architecture and views of the East River. The area is not defined by any tourist attractions, but that is part of the appeal. 733 3rd Avenue is just blocks away from Greek seafood at Arva Esiatorio, a warm treat at Ess-a-Bagel, and the Smith & Wollensky steakhouse - Warren Buffetts favorite in New York. Third Ave and Lexington have stations that are quite close, making transportation easy. After work, the nightlife in Turtle Bay leaves little to be desired.



Midtown is the epicenter of business in New York City, the beating heart of everyday professional life in Manhattan, the "Big Apple" everyone's talking about.  In many ways, it's a microcosm of the city - its own ecosystem of interconnected businesses and neighborhoods. While it's most commonly associated with the modern marvel that is Times Square, there's more to Midtown than jam-packed sidewalks, throttling skyscrapers, and honking taxis.

This is the home of cool districts like Koreatown and Rose Hill, the patron of fine cultural institutions like the Museum of Modern Art (MoMA), the Scandanavian House, PierPont Morgan Library, and the Japan Society. Some of the best restaurants in the world hail from Midtown, like Thomas Keller's Per Se, Takayama's Masa, and Eric Ripert's Le Bernardin. Famed venues like the Ziegfeld Theatre movie palace, Carnegie Hall, and Radio City Music Hall never fail to charm. And we haven't even gotten to the shopping on 5th Avenue or the "Hamilton" craze on Broadway taking the world by storm. So you see, Midtown isn't all work and no play, but it does excel at work when you get down to it.

Midtown office space drives the commercial market in New York City. It isn't exactly cheap, coming at an average of $73/sqft, but its unbeatable public transit options and well-laid infrastructure still make it top dog for big businesses in need of office space for rent. As for the neighbors, take your pick. It's the media and advertising and financial capital of the world.

Nearby Districts Include: The Garment District, the Upper West Side, and the Upper East Side
