Clutter and confusion are failures of design, not attributes of information.
Dont confuse legibility with communication. Just because something is legible doesnt mean it communicates and, more importantly, doesnt mean it communicates the right thing.
Architects have made architecture too complex. We need to simplify it and use a language that everyone can understand.
Make all visual distinctions as subtle as possible, but still clear and effective.
My architecture tends to be legible, light and flexible. You can read it. You look at a building, and you can see how it is constructed. I put the structure outside.
Design should be easy in the sense that every step should be obviously and clearly identifiable. Simplify elements to make change simple so you can manage the technical risk.
