In these images the project isn't yet completed but I thought I'd share them, anyway.
I enclosed the patio so my wife and daughter could use it as a room for their crafting. I imagine using it with the screen doors in place and the patio doors wide open. I think this is called a lanai. We don't have air conditioning; the on-shore ocean breeze is enough, so keeping the doors open is not a problem.
It's done by a serious DIY guy (me) and that is the best I could afford. I built it working alone except I hired a local firm to do the torch-down roof (they finished the day before we got our first rain of the season).
I'm currently installing the electrical wiring. After that, I need flooring and some touch-up painting. I can see the light at the end of the tunnel and it's not a train.
