We would like to add a room to the house and would like it to be in the empty part of the outside under the master bedroom deck. (as seen in picture)
Currently that spot just has dirt on it and would need to be dug up to match the houses basement. The wall already has a window which I guess could be converted to a door that would be an entrance to the room and then a window added to the new structure from the side.
My question is if this is possible and what would be the approximate cost.
