About Titanium La Portada

The building’s design was inspired by the very essence of the “La Portada” area, a geographical gateway shaped by wind and the ice water river flow from the Andes since the ancient glacial period. The main tower’s two glass façades simulate soaring wind-filled sails plying the urban torrent. The visual energy generated by this arrangement is further enhanced by numerous urban features converging to the site, transforming the building into a physical and symbolic referent at the metropolitan level. Also, the building transmits its dynamic energy through vertical cuts in the curved façades along with the helical arrangement of the decks.

The façade reflects the heartbeat of a living, constantly changing environment nourished by the city’s main arteries. The crowning oval rooftop seems to levitate above the building’s ethereal glass sails—a metaphor for the physical challenges involved, met and overcome to realize this project for Chile’s capital. The Titanium name comes from the metal alloy; a resistant, durable and viable long-lasting element.

The building’s erection was only possible due to the development of an anti-seismic technology, contained in several energy dissipaters distributed up along the height of the building. Shortly before the building’s official opening this system was put to the test when a magnitude 8.8 earthquake struck Chile in February 2010. The building survived this monumental seismic event unscathed. The building’s facade is also seismic resistant, with its insulated laminated glass used throughout the entire building. Additional safety features include fireproof pressurized elevators for emergency operation, two pressurized staircases, two external ladders for emergency evacuation and a double helipad on the roof.

The tower has set a new environmental standard for high-rise architecture in Chile, implementing strategies such as: energy behavior monitoring, natural ventilation through operable awning windows, recycling stations on every floor, high-efficiency thermo-panel walls which maximize the entrance of light while filtering solar radiation. Further, more than 70% of the ground level is dedicated to gardens, passages, squares and galleries for the public.
