1+2 go together
3+4 go together
5 is on it's own
I'd like to remove the stairs to get access to the foundation to parge and waterproof, but it's nailed into beams in pics 1-4. Similarly, I'd like to remove the wood where the concrete doorway is but I'm not sure if it's load bearing as well.
Any recommendations on who would be best to talk to about this?
