Curious about what Architects think of this? https://www.higharc.com/
Never heard of it.
Here in New Jersey you are required to have an Architect, unless you are building it yourself....for yourself under "self certification" with restrictions to prevent build-n-flip. And you may still need a PE to review and sign-off on the structure. Most jurisdictions require a design professional in either case..
Now some states like Delaware and in the South don't consider house design as part of the regulated "Practice of Architecture", ...but don't call yourself an Architect unless you're licensed. Bloodgood Associates out of Atlanta and other "Residential Designers" sold thousands of house plans to southern builders and developers. Most of those plans came without structural design, since that would be regulated Engineering in some jurisdictions.
Just like those plan books at your local Barnes&Noble, many typically have intentional errors built-in so you have to buy expensive "detailed plans" from them directly. Or they have omissions and mistakes since they're churned-out without competent review. I've had a few clients who brought me "book plans", and they were terrible quality-wise. One ...the first and second floors didn't line up, nor match the elevations properly.
