I suppose we'll just have to disagree on this....NOW...to expand....I'd would NEVER build a house I planned to live in, without an architect!! I think they are genius's at what they do....drawing plans!! I always had an architect available when building homes in the late 80's & early 90's....BUT I didn't use them to layout a foundation, nor an electrical plan, HVAC plan, roofing plan, or anything else....I had well qualified subs to do that work, AND the county inspectors. I have seen my architect do things I didn't think was possible, and elevations....simply amazing...I just do not need them to tell me how to build a foundation....I have/had others to do that....besides an architect, there are others that can build a foundation, and plan a slab pour, with load bearing footings.....HVAC...does the architect know which way the house faces, as to how the sun will effect heating and cooling in a home?? I say no.....BUT I can promise you, my HVAC company did....
