The base of the building utilizes the maximum area of the site, housing TV studios and , sq ft of retail space over multiple levels. The lobby is connected to the WTC transit hub, providing direct access to subway lines and PATH trains.

Musée Atelier Audemars Piguet is informed by the convergence of form and content in clockwork. It is conceived like the coils of a watch, ticking and advancing in perpetuity like the gallery visitors and watchmakers moving cyclically with the structure. Every element is governed by the functional requirements of the exhibition while appearing as a sculpture conceived in a single gesture. The all-glass structure is made up of two spirals that seamlessly integrate into the existing landscape. The museum’s collection, which showcases some timepieces, is displayed alongside two in-situ production workshops, creating a living museum.

Structurally, the pavilion was a giant self-supporting tubular steel truss, similar to the hull of a steel ship. The external façade structure was the buildings most efficient element. The perforation holes let in daylight and created natural ventilation. It was the only pavilion out of + that did not use mechanical cooling. Due to the structural performance of the truss, the degree of perforation varied with the structural stress along the façade.
