The name “Nube” (Spanish for cloud), refers to the floating form of this structure, but also works as a metaphor for its function. Nube acts as a vessel for ideas, nourishing the citizens of Madrid with an ever-changing cycle of expositions. The continuous-plan concept functions as a base supporting both banquet and exhibition spaces from which visitors rise up into the “clouds” of the auditoriums. LED images, showcasing the activities of the complex, will be projected onto the raised building surface, creating a dynamic, interactive façade. The exhibition hall is a series of long, narrow modules, allowing for an open space that is flexible and sub-dividable, while retaining the ability to be united into a single auditorium for large audiences. The balcony enjoys majestic views of the surrounding sequence of parks.
