Puerta de Europa
These two office towers flank the Paseo de la Castellana, Madrid's most important boulevard. The location of a subway interchange made the placement of the two towers near the street impossible. Their bold design is in part a response to the need for the footprints of the towers to be set back from the interchange while at the same time bringing the towers together as a single compositional whole. The towers lean towards each other and over the plazas, ensuring their visibility from up and down the Paseo and creating a portal which, being at the Northern end of the business district of Madrid, has been called a metaphorical gateway to Europe. The façade of each tower is a composition of a major grid -clad in stainless steel conforming to their structure-, a minor grid of red mullions, and a third grid comprising the light grey mullions of the curtain wall (text from website architect).
