I like the concept but agree with your point (2). Building codes are already strict and yet often the tract houses are still shoddily built.
Generally, it’s a bad idea to be using any construction product unless it’s been around at least a few generations without major issues.
In your opinion, does that apply to stuff like 3d printed concrete houses where the material is very old but the application technology is extremely new?
Buckminster Fuller’s geodesic homes are another - typical materials in atypical layouts.
Tons of weird issues, from leaks in difficult to access areas, to weird condensation problems with no solutions.
Every building has problems. New styles of buildings or new materials create new problems with no known solutions (or no solutions at all), a surprising percentage of the time.
