Work is nearing completion on Google’s 1.3 million-square-foot headquarters at 550 Washington Street in Hudson Square. Designed by COOKFOX Architects and developed by Oxford Properties, the 232-foot-tall building is the centerpiece of the company’s “Googleplex” master plan that will encompass a grand total of 1.7 million square feet across three separate structures. The other two sites include 315 Hudson Street and 345 Hudson Street. Turner Construction is responsible for building the 12-story project over the brick-clad base that was historically known as St. John’s Terminal. 550 Washington Street spans two full city blocks between West Street, West Houston Street, Washington Street, and the New York Department of Sanitation building.
