Torre PwC

The Torre PwC, formerly known as Torre Sacyr Vallehermoso, is a mixed-use skyscraper located in Madrid, Spain. Built between 2004 and 2008, the tower stands at 236 m (774 ft) with 52 floors and is one of four buildings in the Cuatro Torres Business Area. It was designed by Carlos Rubio Carvajal and Enrique Álvarez-Sala Walter and was built by Sacyr Sau. It is the only tower with double skin facade and it is covered entirely of glass in the form of flakes. On the upper deck there are 3 wind turbines, of 2.5 kW each, capable of producing wind energy for use in the building. Spain's short tradition of skyscraper construction, combined with its location in a higher part of the city, creates a striking effect on Madrid's skyline. The Torre stands out among the other skyscrapers in the CTBA (Madrid Business Park) due to the clarity of its volume. The building is fragmented into three sections by fissures, increasing the sense of verticality. These fissures also allow light to enter, creating the illusion of a single structure. The architects of the project are the Spaniards Carlos Rubio Carvajal and Enrique Álvarez-Sala Walther.
