I'm interested in using this method to build for clients. However my main question is, what do you do about building codes? It seems like many building codes would not work with this method. What have you done to work around that? How do you run your electrical and plumbing? Thanks !
Unconventional structures typically require a stamp of approval from an engineer or architect licensed in your county. This releases the county from liability. You'll have to check with your local building department for specifics. They may even recommend someone to you.
