We are all affected by Le Corbusier, Frank Lloyd Wright, Alvar Aalto, and Mies van der Rohe. But no less than Bramante, Borromini, and Bernini. Architecture is a tradition, a long continuum. Whether we break with tradition or enhance it, we are still connected to that past. We evolve.

To be an architect has been a life-long dream. Little did I know when asked at the age of 14 'what do you want to do when you grow up?' I said I wanted to be an architect.
