Structure Tone is a global leader in construction management and general contracting services with offices located in the US, UK, and Ireland. Founded in 1971, the company is among the world’s top twenty construction companies worldwide, responsible for more than $3.5B in annual construction volume.
Built in the 1980s, 520 Madison offers premier office space in a prime location. To create more commercial space for tenants at the top of the 43rd floor—plus a 2,200sf landscaped terrace—the mechanical equipment room (MER) had to be relocated to the roof and elevator access extended to the top level.
