We know what we want, this is where we figure out how, exactly, we're going to make it happen. This is full-on nitty gritty; permit drawings represent the main bulk of the technical work necessary for a formal construction-permit submission.

Ultimately we'll end up with fully developed and code-compliant descriptions of everything, as well as all the structural/mechanical consultant contributions (stamped by professionally qualified engineers.) Permit drawings are often required for project financing, and will form the basis of the contract between you and the construction team.
