Resolved I made a house, but its not valid.

This is my first time making a proper house, and all my other ones are just boxes. I'm unsure as to the reason why, but it may be because there is mud for the walls. idk if this is the issue, as I said, I mostly just build boxes. When I use the housing query it just gives me the message; "This room is missing a wall"

If those are not player placed dirt walls, then that is your issue I think.

The background walls of your house are natural dirt walls, natural walls aren't valid for housing so you'll have to remove them. Natural walls are also unique in how to remove them you have to use a hammer and start from the edge of the walls and work your way inwards
