Occupying 6 floors and 250,000 square feet within Time Warner Center, Kostow Greenwood designed CNN's prime-time production hub to be as dynamic as the location's Central Park Views.  We created a public tour route throughout the venue with viewing platforms that allow visitors a glimpse into the inner workings of the fast-paced world of news gathering and production. CNN films throughout its facility therefore all materials within the broadcast center were camera tested to ensure on-air compatibility. Included in the program are a fluid series of newsrooms, open studios, a black box studio, production and technical facilities.
