Hand Drawings
Architecture is a constant process of layering and working through iterations to arrive at a solution. Drawing has been my best tool for that. I strongly believe there is no better way to quickly express your ideas so directly than with pencil and paper.
I am reminded of how effective a tool it is after hours of struggling on the computer with an idea - when I get it out on paper through a drawing, it comes immediately. My goal has been to stike a healthy balance between the computer and hand drawing.
