Why Architecture?

“I do feel there is something innate in those of us who choose to be architects, and we often start showing signs of this love of designing and building from an early age. I find architecture to be a fascinating field in which I am continually in awe of the array of design work my contemporaries and I are able to produce. The late Scandinavian architect, Alvar Aalto, is someone I’ve always admired. I see the impact of his simple lines and organic details impacting our profession today.”
