On this week's episode of Archinect Sessions we talk with Carlo Aiello, a Mexican-born, LA-based designer and founder of eVolo. Most of our readers are familiar with eVolo's (very) popular annual skyscraper competition and related series of books. Carlo, the founder of eVolo, is also the designer of the award-winning Parabola Chair and the designer of the Kickstarter-success ESCALA, a 2-in-1 drawing tool combining the scale-ruler with an insertable fountain pen. In our conversation we track his progress from his studies at Columbia's GSAPP, to working for SOM and Asymptote, to embarking as a self-made entrepreneur with a move west, to LA.
