Not sure if this is the best place for this post or not but I'm working on an addition plan and I want a zero step entry through a slider or French door. I was wondering if anyone here had experience with zero step entries and any tips or comments about them. My thought was to have concrete or pavers outside the door and grade down to an existing concrete surface. It's 2 steps up to the house floor now, the addition would probably be the same level. I can't in my mind figure how to build the structure to allow dirt to be sloped up against it. Thoughts?
