Law firm Duval & Stachenfeld LLP is preparing to move to new offices at 555 Madison Avenue, also known as the Coates Building, in the pricey Plaza District.

The company signed a 13-year lease for 50,000 s/f of space in 2011, but the move was delayed until this month.

At the time, managing partner Bruce Stachenfeld said, “I can’t claim to have a crystal ball, however I like the idea of locking in our leasing costs now (20 months ahead of time) rather than taking my chances on the leasing market in a year.”

Asking rents in the building were then around $59 a square foot. Plaza District asking rents today stand at $77.17 psF.
