Estel Barcelona

Estel Barcelona, an iconic landmark in Barcelona’s Eixample district, has undergone a major transformation in recent years. Originally designed in the 1970s by architect Francesc Mitjans as the headquarters of Telefónica, the building has been fully refurbished between 2023 and 2025 to meet the standards of a modern office complex. Led by BCA Arquitectura, the project focused on sustainability, transparency, and opening the building to the city.

The intervention sought to radically reimagine the former “opaque bunker” as a bold, light-filled structure—open, transparent, and fully engaged with its urban surroundings.

In collaboration with Garcia Faura, our team contributed to the project by performing detailed structural verification and engineering calculations for the façade systems. Our scope included analyzing structural loads, anchoring strategies, and façade element behavior under service conditions, helping ensure the safety and performance of this complex and technically demanding envelope.
