Guy I know is interested in pursuing a small house design with cantilevered decks. This, to have a cool Frank Lloyd Wright look, and to avoid the posts, columns, and piers that would be required otherwise.
The key to it all is that the decks have “solid” railing walls and “thick” floors that conceal the structural steel frames that hang onto the outside of the building frame.
We’ll begin the engineering for the steel with the concept drawings, shown attached.

I cant fault the elegance of it.
But, I'll guess that you will get some "Why dintja use (engineered)wood instead?" posts here.
I've had to explain the need to have some elevation change, from indoors to out, and how that can complicate the elegance of using long continuous structural members elegantly.
Good on'ya, as my Digger friends say,
