As the ultimate DIY project, I want to owner-build a home. I've already "designed" the house, meaning I have a 1/2" scale floor plan, roofing ridge line, and elevations for all interior and exterior wall treatments. These are all done in CAD. I know exactly what it will look like inside and out.
In order to build it though, I need building plans, maybe stamped by an architect. The person who makes the plans would need to be qualified to make structural engineering decisions and calculations, like joist spacing, wall framing diagrams, and foundation calculations which I am not qualified to do.
So far, I've found four types of people, none of which will do what I want:
Architects want to design the house themselves, and seem offended that I would come to them with specifics about exactly how the house should look and be laid out.
"Residential Designers" seem to be draftsmen that also want to do the design elements themselves. I'm also not sure about their qualifications for engineering calculations.
Design and build firms want to do the design themselves and build the house too!
Most engineers only seem interested in commercial projects, and it seems like over kill to hire an engineer ($$$) to draft building drawings for a small residence.
So if I already have a complete "design" for the house (layout and artistically speaking) but need that design turned into structurally sound and code compliant construction drawings with the proper legal approvals, who is the right type of person or firm to do this work?
