Santiago Calatrava Valls is a well-known Spanish architect, engineer and sculptor. Born in Beninanet near Valencia, he attended the School of Arts and Crafts and then the School of Architecture. In the following years he was influenced by Swiss architect Le Corbusier, allowing him to examine how complex forms can be understood and generated in architecture. In 1981, after his PhD in Civil Engineering, he began his career as an architect and engineer in Zurich. Calatrava's projects combine the visual conception of architecture with the principles of engineering, inspired by the forms and structures that form in nature. In addition to being a recognised architect, Calatrava is also a sculptor and painter, succeeding in combining all the arts into one. One of his most recent projects is the construction of a residential skyscraper of twelve cube-shaped terraced houses stacked one on top of the other in New York. Calatrava's inspiration is usually expressed through the production of watercolour sketches on the basis of which an architectural and structural design is then developed by his studio.
