The building at 809 United Nations Plaza in Manhattan, New York City, houses the Edgar J. Kaufmann Conference Center. It was announced in 1962 during the construction of the Institute of International Education (IIE) headquarters and dedicated in December 1964. The conference center was designed by Finnish architect Alvar Aalto and is one of his few remaining designs in the United States.

The IIE building, a 14-story glass-walled structure, was designed by Harrison, Abramovitz & Harris. It features about 100,000 square feet of floor space and includes a 300-person meeting area on the 12th floor, where the Kaufmann Conference Center is located.

In 1998, the building was sold to a group backed by Japanese financiers. Despite efforts to preserve the conference center as a landmark, it was not designated as such due to its private nature.

Why Optimal Spaces –
Tenant Broker

  • We work for YOU, not the landlord.
  • Save 15–20% on your business costs.
  • Save 100–200 hours of research.
  • Access to all available spaces.

Alone or with other broker

✕
  • Miss deals and hard-to-find spaces.
  • Potential conflict of interest (often represent landlords).
  • Only 10% of available spaces are online.
  • Lack of specialized expertise.
  • May not get the best terms or uncover hidden costs.
Why Use a Tenant Broker: Your Advocate in Commercial Real Estate
1. The Crucial Distinction: Whose Side Are They On?
Landlord Rep (Listing Agent) — Fiduciary Duty: Landlord. Highest rent, best terms for landlord.
Tenant Rep (Tenant Broker) — Fiduciary Duty: Tenant Only. Lowest rent, best terms for tenant. Levels the playing field.
2. It Almost Always Costs You Nothing
3. Access to “Hidden” Inventory
4. Negotiating Beyond Base Rent
Landlord pays the broker fee — free expert representation for the tenant.
Access to hidden inventory: off-market listings, subleases, and future availabilities via broker databases and networks.
Negotiating beyond base rent: free rent, TI allowance, OPEX caps, and lease flexibility for renewal or expansion.
5. Time Savings & Process Management
6. Mitigating Risk (the “Gotchas”)
Tenant broker handles searching, scheduling, and RFPs — your outsourced real estate department with curated options and timeline management.
Mitigating risk: spotting pitfalls in LOI and lease such as restoration clauses and holdover penalties.
Summary: Don’t rely on the landlord’s agent. A tenant broker is your advocate, provides better data, negotiates a complete package, and typically costs you nothing.
