This global advertising agency’s corporate headquarters recently relocated to 636 Eleventh Avenue, a single tenant occupant building in an upcoming neighborhood in Hell’s Kitchen. Constructed in the shell of an old factory, the goal was to create a wide-open, green workspace for the company’s 2,000 employees that would maximize the flow of ideas and information. The newly renovated space, totaling 565,000 sq. ft. over 11 stories, includes a lower lobby concourse, two outdoor roof gardens, a state-of-the-art multipurpose theatre, café, data center, and fitness and wellness center. Completed on a fast track, the new eco-friendly offices—with abundant natural lighting, low flow plumbing fixtures and over 500 individual temperature control zones—attained LEED-Gold CI certification.
