Why Optimal Spaces Tenant Broker

  • Lease negotiation: full terms, renewals, expansion options
  • Cost analysis, inventory identification, negotiating scope
  • Risk mitigation against hidden pitfalls

Cost Savings

  • Negotiate 30+ leasing points to prevent hidden costs
  • Save 10–15% on total leasing costs
  • Save 100–200 hours filtering unviable spaces
  • Property access via broker databases and networks (off-market, subleases, future availability)

Alone or With Other Brokers

  • Managing agents owe fiduciary duty to landlords, seeking maximum price and terms rather than tenant savings.
  • Inherent conflict of interest as most brokers represent landlords
  • Risk of weaker terms and overlooked hidden costs
  • Heavy workload falls on you while best spaces are missed

44 Union Square East, known as the Tammany Hall Building, is a prominent neo-Georgian structure located at the southeast corner of Union Square East and East 17th Street in Manhattan, New York City. The building was erected between 1928 and 1929 by architects Thompson, Holmes & Converse and Charles B. Meyers for the Tammany Society, a historical political organization also known as Tammany Hall.

Designated as a city landmark in 2013, the building underwent significant renovations between 2016 and 2020, led by BKSK Architects. The landmarked north and west facades were preserved, while the interior was rebuilt to accommodate modern office and retail spaces. A notable addition is a glass dome inspired by the Lenape creation story, symbolizing a turtle shell, which adds approximately 30,000 square feet to the building.

The glass dome was structurally completed by July 2019 and the entire project was finished by October 2020. This design blend of historical preservation and contemporary innovation earned several architectural awards, including multiple awards from the Society of American Registered Architects and the American Institute of Architects.

TPG Rewards Testimonial

TPG Rewards testimonial To whom it may concern, This letter is written in support of Mr. Stephen Sunderland. Mr. Sunderland acted as our advisor and broker in our recent search for office space in Manhattan. From our first meeting Mr. Sunderland sought to understand our location, price, office layout and square footage needs. He closely accessed our initial needs, and made realistic suggestions to improve on them. The true measure of Mr. Sunderland's professionalism is that he delivered listings, and ultimately a deal, that closely related to our initial wishes and needs. Throughout our relationship he gave us sound advice as to the pros and cons of each location, and later on how to best work with the landlord in order to create an amicable deal. Mr. Sunderland is a knowledgeable real estate professional who I recommend without any reservation. Sincerely, John S Galinos,President and CEO, TPG Rewards Inc, 111 John Street,27th Floor New York, NY 10038.
