City Square leads the Westchester County office market with abundant amenities, including lobbies that feel more like a boutique hotel than a traditional cold sterile office building lobby that’s more reminiscent of a mausoleum.

And only City Square has its own Central Park!

Work. Live. Play.

At the entry to downtown White Plains has long stood the iconic Westchester Financial Center. Now under new ownership and renamed City Square, this exciting complex is undergoing a modernization by Ginsburg Development Companies and is being transformed into the premier location to Work, Live and Play in Westchester County.
