The renovation of Benito Villamarín Stadium in Seville, Spain, has officially begun, led by Acciona in collaboration with Real Betis Balompié. This first phase focuses on excavation and the installation of diaphragm retaining walls to prepare for new below-ground levels. The multi-stage redevelopment project aims to enhance the stadium's capacity and modernize its facilities, including plans for a new stand, refurbishment of existing seating areas, and the construction of an adjacent mixed-use structure. The project will also introduce several underground parking floors, a new roof, and an updated facade for the stadium. Efforts will be made to ensure urban mobility and minimize noise disruption in the Heliópolis neighborhood. Acciona's previous projects include the Rafael Gordillo Training Complex and other significant sports infrastructures across Spain, emphasizing sustainability and advanced technology.
