Arup collaborated with L. Benjamin Romano Arquitects (LBRA) to design Torre Reforma’s eye-catching triangular form that rises as the second tallest building in the city. The striking appearance was achieved with pre-tensioned double-V hangers that support the glazed facade. Concrete poured in 70-centimeter increments show off striations and variations in color.
To make the most of Torre Reforma’s stunning panoramic views, the architects created a column-free interior with soaring ceiling heights. The egress stairways and 35 elevators—Torre Reforma is the building with the most elevators in Latin America—are located in the corner, or “apex,” of the triangular plan. “Because Torre Reforma is triangular in plan, the building has an inherent tendency to twist when subjected to lateral loads and wind, not to mention earthquake forces,” says a press release. “Arup applied a comprehensive time-history analysis to establish the performance of the structure under extreme seismic conditions and engineered a solution that is both locally appropriate and consistent with international best-practice designs for tall buildings.”

Torre Reforma is expected to attain LEED Platinum Core and Shell certification. The building boasts rainwater collection as well as a graywater and blackwater recycling systems. Automated and passive ventilation moderate interior temperatures, while concrete walls shield the interior from unwanted solar gain.
