The Glorieta Cibeles Tower is a complete up-cycle of a structure abandoned after the historic 1985 earthquake. Designed as a sculptural inhabitable obelisk, the transformation comprised four fundamental axes: structure and resilience; comfort and functionality; aesthetic and tectonic design; and sustainability, in operational and embodied energy. The intervention demonstrated that old deteriorated structures can be revitalized while exceeding all the current requirements of comfort, efficiency, sustainability, resiliency and flexibility, becoming an example of urban recovery and renewal.
