We changed from stairs to a ramp to make easier access. I'm a clutz. I can't tell you how many times I tripped on the stair of our other GH. Our concrete guy thinks of everything and added a drain due to the slope.
Oops. The directions for feet support were very vague and our knee wall is too far inside. However, after measuring the feet they would not have fit anyway. Brilliant fix suggested by Paul to add pressure treated cripple studs recycled from our old GH. I knew there was a reason that we spent the time to take apart the old one and save the materials. We will need corner cripples plus a stud post. Easy fix. The frame is going up!
