Forget everything you think you know about Midtown East office buildings. 820 Second Avenue office space sits right in the diplomatic heart of Manhattan, where international deals happen daily and your business can tap into a network that spans the globe.

A Building with Serious Diplomatic Credentials

820 Second Avenue earned its stripes back in 1964 when architect George Greene designed what would become the Diplomat Center. You’re looking at a building that has hosted international negotiations and housed foreign consulates for decades. The owners didn’t let it sit idle either. Major renovations in 1988 and 2008 keep this 19-story tower operating at peak performance. Each floor operates as a separate commercial office condominium, giving you flexibility that traditional lease structures simply can’t match.

Office Spaces That Work for Your Business

Your team gets access to 164,758 square feet of Class A office space that delivers on both form and function. Floor plates typically span 9,600 square feet, giving you room to design layouts that actually support how your people work. The 820 Second Avenue office space comes as individually owned commercial condominiums, meaning you can rent or buy depending on what makes sense for your growth plans. Plus, you get over 11,000 square feet of retail space at street level, perfect for client meetings or grabbing lunch between calls.

Amenities That Benefit Your Operation

The building management at 820 Second Avenue office space knows that small details make or break your workday. Here’s what keeps your business moving:

  • 24/7 Building Access: Your night owls and early risers can work when inspiration strikes, not when building management says so.
  • Attended Lobby Service: Professional staff handle your visitors and deliveries so you can focus on closing deals instead of managing logistics.
  • On-Site Security: Your people and equipment stay protected around the clock with dedicated security personnel who know the building inside and out.
  • Professional Management: Phillips International handles building operations so you don’t have to worry about maintenance headaches or service interruptions.
  • Four Passenger Elevators: Your team and clients move efficiently between floors without those awkward waiting periods that kill momentum.

Getting Here Couldn’t Be Easier

Your commute stress disappears when you choose this Turtle Bay location. Grand Central Terminal sits just blocks away, connecting you to the 4, 5, 6, and 7 subway lines plus Amtrak and MetroNorth services. That Times Square shuttle puts you in the heart of the action whenever deals demand it. International clients love the 15-minute drive to LaGuardia Airport, making those last-minute meetings actually possible. The United Nations headquarters practically shares your neighborhood, along with major players like Bank of America.

You’ll Be in Exceptional Company

Your business joins a tenant roster that includes some seriously influential organizations. Diplomatic missions from Croatia, Peru, and Barbados conduct international business right down the hall. Northwell Health, William Schwitzer & Associates, and the United Synagogue of Conservative Judaism call this building home. Even Hallmark maintains a presence here. When your clients see your 820 Second Avenue office space address, they know you’re operating at a level that commands respect.
