Hi, im in need of a crawl space entry door. The house sits pretty low and the door would be lower than the grade of the yard. I've googled images but not really found anything that i think would be best for me. Right now i basically just have a hole in the foundation that was already there. So i was thinking about laying blocks down to the depth of the sewer pipe where it exits, about two blocks high, and wood framing on top of that. And the door would be a lift off door angled similar to the way an old cellar door would look. And just filling the area level up to the yard. Any ideas or pictures would be great. Also, are there rules or codes concerning the doors?
