The Iberdrola tower is located on the Plaza de Euskadi and is part of the new urban development: Abandoibarra in Bilbao. Cesar Pelli designed the master plan for this former brown side area including the tower. The building is the headquarters of Iberdrola and recently opened on 12 February 2012. Construction started in 2007 and the total costs were 200 million. The building contains approximately 8,500 tons of steel and 60,000 tons of concrete and has 41 floors with a total area of 50,000 square meters. The building is 165 meters high and with that the tallest building in the Basque Country.
The tower has the distinctive shape of a triangular prism, with clear lines slightly tapered towards the sky, which suggests of a large crystal obelisk. The facades, consisting of a double wall of glass, offer a sustainable solution, with an efficient air condition system and beautiful views over the city and the river.
