Glass-lined corridors and exposed ceiling infrastructure set a modern tone as the layout unfolds from a direct elevator entry into a wide internal circulation path that connects two distinct suite configurations on the partial fifth floor. The larger portion of the space organizes itself around a central open work area, where multiple benching rows accommodate a dense team environment that can comfortably support approximately twenty to thirty workstations depending on final configuration. This open zone is surrounded by a series of enclosed perimeter rooms that function as private offices, small team rooms, or breakout suites, with roughly six to eight such rooms positioned along the window line to take advantage of exterior exposure and views toward the river.
A formal conference room is located along the perimeter, sized to handle larger meetings and presentations, while additional smaller meeting rooms and enclosed collaboration areas are distributed nearby to support internal team discussions. The layout transitions naturally into a lounge and informal seating area that acts as a buffer between workstations and enclosed offices, creating a flexible environment for casual meetings and day-to-day interaction. A pantry anchors the interior portion of the suite, designed with bar-style seating and open access to both the workstation area and surrounding rooms, reinforcing it as a central hub for staff.
The secondary suite portion extends off the main corridor and offers a slightly more private configuration, featuring several additional enclosed offices and smaller meeting rooms that can function as executive suites, partner offices, or client-facing rooms. This section also includes dedicated storage and support spaces, making it well suited for a team that requires separation between departments or leadership and staff.
Throughout the layout, glass-fronted offices maintain visual continuity while allowing light to move across the space, and the combination of open ceilings and modern finishes creates a contemporary office environment. The overall plan provides a balanced mix of open seating, private offices, and collaborative rooms, making it adaptable for a range of users from advisory firms to creative teams seeking a polished, move-in ready installation with strong layout flexibility.

About the Building
866 United Nations Plaza is a prominent office property located at First Avenue and East 48th Street in Midtown East, directly adjacent to the United Nations Headquarters and overlooking the East River. The building offers a distinctive combination of waterfront views, flexible office layouts, renovated common areas, and immediate access to the diplomatic and institutional core surrounding the United Nations.
The property contains more than 175,000 square feet of commercial office condominium space, with suites ranging from smaller individual offices to very large contiguous blocks. Floor plates are designed to accommodate a wide variety of users, including professional services firms, nonprofits, international organizations, diplomatic-related businesses, law firms, and companies seeking flexible Midtown East office space.
Office interiors benefit from high ceilings, oversized windows, abundant natural light, and protected views of the East River and United Nations complex. Available spaces range from fully built, move-in-ready offices to open white-box configurations that can be customized for a tenant’s needs. Large contiguous opportunities are also possible, including floor configurations exceeding 40,000 to 60,000 square feet.
The building underwent a substantial renovation that included a new entrance, updated travertine lobby, modern elevators, renovated corridors, and upgraded tenant amenity areas. Shared amenities include breakout spaces, reading areas, lounges, galley-style gathering spaces, and private phone booths. Large-scale digital artwork within the lobby adds a contemporary element to the building’s arrival experience.
The property’s position along the East River provides unusually open views for Midtown Manhattan. Offices can overlook the United Nations gardens, East River, Roosevelt Island, Queens skyline, and surrounding Midtown buildings, creating a workplace environment with significantly more open exposure than many traditional Midtown office properties.
Transportation is accessible despite the building’s east-side waterfront location. Grand Central Terminal is within walking distance, providing access to the 4, 5, 6, 7, and S subway lines, Metro-North Railroad, and Long Island Rail Road. The 6, E, and M subway lines are also nearby, while Select Bus Service along First and Second Avenues provides additional north-south connectivity.
For companies searching for office space near the United Nations, 866 United Nations Plaza offers renovated interiors, flexible suite sizes, large contiguous opportunities, oversized windows, exceptional East River views, and a uniquely international Midtown East location.
