I think that if an architect knows where the clubhouse area will be on the site he's designing on, he ought to make the 18th hole the first one he/she designs. It should be the most carefully designed hole. Even if most matches DO end around #16, a) most people who play golf are not playing matches nowadays, and b) if a match has made it to the 18th hole, it deserves to end in the most climactic way.
In fact, now that I think of it, it seems best to design whole courses backwards (perhaps with the exception of the first couple holes and the last couple). This eliminates running out of room (if that's an issue) for the most critical holes on the course. I do realize that the terrain has bearing on this, but it makes sense to me, to start at the best part, and design backwards accordingly.
