Yard shed redo

[u/Sigma--6]

There was a shed in the yard when my daughter bought her house. It's in rough shape, but I think I can save it. The door is made of the same T-111 pressboard used in for the walls and is the biggest issue. I looked into a roll up door but they need a fair amount of overhead space. The shed at my house I built I used a 36" steel entry door and I'm thinking of doing that here. I plan on removing all the 1x4 particle board trype trim and repairing the walls with new nails or screws to the 2x4 then a lot of caulk and primer and then paint. Then new white trim, maybe pvc or primed pine.

For the door I need a piece of the T-111 and 2x4s to reframe the rough opening for the single door. They only put a push mower, spreader, yard tools, chairs, etc in there. I think the single door would be ok.

Any thoughts or advice?https://imgur.com/a/EXmYMvz
