Santiago Calatrava is passionate about architecture, but his passion goes much deeper than the aesthetics of good design. Inspired by nature, by great art, his buildings are undoubtedly beautiful but for Calatrava they only become meaningful when they interact with people's everyday lives. As he says of The Chicago Spire, it is the people who will live there that will "give life to the building." Calatrava is already thinking well beyond the design and build process to the time when the residents will arrive home and "enjoy the light of the city, the changing of the seasons, the changing of color...a sunset." Hear for yourself his vision, his wholehearted commitment to this great building, in two short extracts from an exclusive interview at www.thechicagospire.com
