That picture might be deceiving. The entrance is only 1 1/4" higher than the driveway level,1/4" per foot of slope with a 5 foot front apron. I'm going to see the truss company tomorrow and get some exact measurements on the trusses. I haven't framed the walls yet so I'll max them out. The drain pipes are the perimeter drain that runs next to the footer. The two vertical pipes at the back are required clean outs. The other set of pipes are the eaves drains, both tie in together before that concrete cylinder, sump, and then runs to the drainage ditch. Everything I am doing is code for this area. I have decided to build swing out doors. Don't want the roll ups, they would interfere with my lighting inside. Still open to bi-fold too. FriedGreenTmater, how could I make my floor a foot lower? That would put it below grade. I must be misreading your idea. The foundation wall is only going to be 5" above grade by the time I surround the shop with gravel.
