If the architect is a better friend to you than you are to him (since you apparently have little interest in his profession, as you involve him in your construction project more as a rubber stamper), then first of all he will give you a proper scolding because despite recognizing that high-quality construction would be appropriate for the status of the location, you are messing around with amateur planning like an apprentice magician. By the way, it is not part of the tasks of building authorities to coach hobby architects.
