I'm super excited that this is finally finished. So much so that I'm looking at renting instead of selling. Thank you all for the help and support guys.
I especially like the doors. Can you tell us how they were made? I'm guessing 2x4 innards and sheeted with OSB on both sides? Anything special about the hinges or locking mechanisms?
2x4 frame to match thickness of the wall. OSB/wrapped/covered in siding. 10" hinges attached using the short horizontal pieces of 2x4 on the back. I don't particularly like how short the 2x4s are behind the hinges...but I cant do anything about it now that its sided. I have a feeling after a few years the hinge screw holes might widen in the OSB. I need to sheet the inside of the door to stop moisture from hitting the back of the door if it rains with the door open.
Special locking mechanism? Yes. The short 2x4 in the middle with 2 deck screws

I haven't decided on a locking solution until...
Chris, I would try to find some something from National Hardware (brand) to lock the doors. On one door, I would put a cane pin at the bottom which would require a hole drilled in concrete. At the top of the same door would be a pull down lock like a foot bolt, that should secure one door.
On both doors I would put a hasp between them and use a padlock. This is what I made for my garage shed door.
GREAT idea! I planned to use a rod type mechanism into the concrete and accepted the fact I would have to go in the side door to open/lock the front. However, I didn't think about using a hasp between the doors and a padlock. This way I can use the front outside lock during frequent entries and use the rod into the concrete for nightly/weekend locking. Brilliant!

I put
over a year into researching and planning this project. The important thing to remember is if you don't know what to do, ask. Whether its google, this forum or an experienced friend...make sure you know what you're doing. Structural integrity of a building is not something you want to take lightly. Hiring an experienced framer was the best decision I made. The bonus was he also knew how to roof, siding and in these economic times only wanted $15/hour.
I'm enjoying re-reading all the comments about tearing it down for a rebuild. Although I have no idea how this building was standing with the bottom foot of all studs and sill plates completely rotted out...
it was still standing, which means it could be saved. I will reorganize the first post out of appreciation for everyone's help and to hopefully give someone ideas and motivation in the future.
