This is a perfect combo of my two favorite ideas for that space under the stairs leading to the basement. A reading nook AND book storage and shelves . assuming that there is enough space for this there.
built in four 4 bunk beds in one room, with stairs in the middle. this will probably happen one day! one HUGE room for the kids with bunk beds against one wall. with the way we are popping kids, lol, i see this happening!
