Sorry about the blowout--it can be repaired, but it is an added expense.
This is the first time I have seen your thread, and on the door question, what I did on one end of mine was to frame in from a standard 8x10 opening (all screwed so reversible), then added a bargain double french door--mine is an Andersen. You see them on FB Marketplace sometimes--they get ripped out, and are sold without frames--I think I paid $100 for the two sides (2x36") with locks and knobs. The other expense was a commercial style threshold @ $50 or so...
I then framed the door up (Cheap HD door frames but marked down, 2 kits)--not dead easy because they are made with a proprietary frame--so I have full glass for light, a lockable sealed door, and it is wide enough to take large stuff through the shop.
