The Cube Tower is a 70m tall office building in Guadalajara, Mexico designed by Catalan architect Carme Pinós. It has 19 floors plus a basement level and was constructed between 2004-2005. The building was designed to maximize natural ventilation and light through its three concrete core structure, which contain elevators and services. Large cantilevered slabs projected up to 10m from the cores, supported by post-tensioned steel beams and allowing open floor plans with few interior columns. This innovative structural system, along with a double-skin facade, terraces, and an atrium space, minimizes the need for mechanical cooling in Guadalajara's climate.
