First, pick a font with some flavor that goes beyond Helvetica and Times and use it in your work. There are thousands available. Second, figure out how to create output that uses color. Third, learn how to use your CAD system's capabilities to fill in columns and walls where appropriate. For elevations and presentation work, create characters, scale figures and landscape elements from scratch that reflect your firm's personality-don't just accept the symbols that come with whatever CAD system you purchased.

Our style is a significant part of who we are as designers. It is what defines us as creative and differentiates us from each other. It sets the table and permeates our design work.
