All internal walls our house are studwork rather than block. Under the top end of the stairs (if that makes sense - where there's more headroom) is a small utility room but the bottom half is completely closed in. No understairs cupboard.
I'm assuming it's just a void under there and we* could open it up and make it either a cupboard or just an open area for storage/shelves. Has anyone done this? How big a job was it and most importantly was it horrendously messy?
Thanks!
