This one has never been used but the other was filled with coal. I found the coal room when I was trying to figure out where the ashes from the fireplace go (it has a trapdoor).
We have the floor removed in the entry which is why I can currently see it!
I do not need the space so I won't be adding a door. It is nice to know that I have the space if I ever want it :)
Some part of me just loves the hidden spaces found in old houses!
