Project Size

105,816 sq m




Las Arenas is a historic bullring, constructed at the very end of the 19th century, and the aim of the new project was to redevelop the existing building in a major new mixed-use leisure and entertainment centre. Fot such purpose, the redevelopment retained and refurbished the striking mudejar façade designed by the Catalan architect August Font i Carreras.

The surface was distributed into a 46,973m² central building, 5,500 m² Eforum and a 53,343 m² car-park. The investment exceeded €190M and the M&E installations budget was €19,8M. The Building has a diameter of 52 meters, and encircles a modern domed complex with eateries, gym, retail shops, cinemas, and a Rock Museum; all spread over six floors focused around a central event space. The rooftop promenade, which is accessible either via a series of escalators or via an elevator attached to the exterior of the building, offers great 360 degree views over the surrounding area.


JG Ingenieros were responsible for the building services engineering design and construction supervision of the new Las Arenas Shopping & Entertainment Center in Barcelona, Spain.
