I realized I have a free wall that follows the steps down to the basement that we COULD put up a faux stone facade on. It would add texture to the main floor's living room space and interest on the way down the stairs to the basement.
We show two good ways to insulate and finish a basement or concrete wall. A 2x2 wall saves space and a 2x4 wall is easier to assemble and insulate. Both will create that snug extra room you need.
