Not being from the nor`east I had to google saltbox style roof. Like others have said, make sure you can fit in the run. I'd think three times before building a raised floor coop, think about you crawling inside to clean, think about you crawling under to clean, think about you crawling around in there. So it sounds like your thinking of building a L shaped coop and run, it would be much easier to build a straight coop and run as one building with the coop part at one end.
If I had the experience I now have my run would just extend out more and have the coop as part of the run. Here you can see my raised floor coop at the end of the run and while it is cute and looks like all the photos you see on the internet it's a terrible idea.
Here you can see I learned more and added a large overhang to the run to keep the rain off my nest box which I learned must be lower than the roost.
What I would do if i did it over I would make large overhangs including the front and back and have a walk in coop.
Here is a WIP photo of my new coop, I'm converting a 12' x 16' shed into a coop. I've got the roost and poop board done, just need to finish up the walls and install my auto door then then then...
