Perry, if what I am reading, you are building this barn with the thought that at some point in time it could be converted into a residence? Also, did someone write that there is a view from the back of the barn?
If that is the case, from a female's perspective, I would build the peaked roof barn and put the front door on the front of the house (duh) and possibly put windows on either side so that it looks like a home. Then, I would put a bank of sliding or folding glass doors in the back of the barn. You could have your driveway go around the back of the barn, offload your stuff right there and bring it in through the opened glass doors. You could even pour a slab in front of the doors and it could serve as an offloading area and a possible patio for the future residents to use as a patio and have a nice view. Also, if you are considering a conversion at some future time, I would suggest you visualize what the floor plan would be like now so you put your water and septic in a place where it could stay and serve the bathroom and future kitchen. Might also want to consider where you would locate a kitchen and then you could install your outlets above kitchen counter heights. Typical woman, always thinking wayyyyy ahead. Good luck with your project.
Oh, one other thought......radiant heat in the floor before you pour your slab???
