It probably goes without saying that drawings are pretty essential. They are how we effectively communicate the design. As we produce the drawings, we test different ideas, always looking for opportunities to enhance and refine the design. Starting on site without a drawing is like starting on site without your toolbag! Each pen mark you see on the paper tells you something about the design. From how long a section of wall is, to where a beam passes overhead. From which way a door opens, to where the window sits both in plan and elevation. From where the last step lands, to where the lightswitch is located. It may be a piece of paper. But it’s so much more than that. It’s an essential tool in any build.
