Building one structure is a series of low skill tasks.
Building many structures (or any given sub-specialty, e.g. plumbing) on a predetermined schedule and budget and making money doing it without charging so much money that you get undercut out of business is what requires skill.
For N=1 you rarely have to be a pro to do it right.
