The project transforms the historic San Carlos de Apoquindo into a contemporary venue, expanding its capacity from 12,000 to 20,000 spectators and incorporating a set of innovative solutions in structure, sustainability and user experience.

The transformation delivers a venue capable of hosting events year-round and places Club Universidad Católica at the forefront of sports infrastructure in the region.

The intervention preserves the original stands and integrates them into a new architectural system composed of a 360-degree perimeter boulevard and a lightweight upper extension that redefines the stadium’s identity. 

The proposal stands out for its sustainable approach: it reuses the existing concrete structure, incorporates 1,600m³ of Chilean laminated timber—which captures more than 1,500 tons of  CO₂—and recycles demolition materials such as steel and plastics. The timber-slat façade and the mixed timber-and-steel roof optimise lighting, ventilation and acoustic comfort. 

With this recognition, IDOM strengthens its position as an international benchmark in sports infrastructure, reinforcing a trajectory built on innovation, structural efficiency and a strong commitment to sustainability.
