With some 200 million users, Telefónica is the leading telephone company in Spain and one of the largest in the world. One of the most important strategic operations for the Group was creating space for 14,000 employees and all its offices in a 400,000 m2 headquarters, called the District C Communications City, in Madrid.
It is the largest, most complicated office complex in Europe: 15 buildings under one roof protecting them from the sun which converts energy into electricity using solar panels. The complex also has restaurants, gyms and wellbeing centres.
