I think we could create a similar aesthetic with a parge.
Possibly parge the interior as well, figure out a way to use the existing screens.
Just like how this one falls into landscape.
Like the idea with an extended porch if you are wanting to install french doors and remove garage door.
Smaller version of this possibly, the side load would be a great place to keep your new fishing kayak.
