Formerly scattered among 13 separate villas, the administration of this TV network is now housed in a single building, with the different working areas located on separate levels. The open-plan layout permits a flexible ar­range­ment of spaces and provides scope for sub­sequent changes of use. It also allows daylight to penetrate into the depths of this ­50 x 50 m building. The interior is distin­guished by its generous circulation routes, with ramps, walkways, monumental steps and cascades of stairs forming a “promenade architecturale” that  leads past the working plat­forms and up to the landscaped roof garden.
