Hard to find vintage cupboards like this. Take a bookshelf, add some old dresser legs or furniture wheels, bead-board for the back, crown molding on top and finish it with what ever kind of door you'd like.
Stairs: but not as beautiful as it being a completely floating staircase. IMHO- those make more of a statement. Haha! Who am I fooling! These are dramatic & ornate enough on their own. I guess I just appreciate the ingenuity of the first architect that had the vision to make the first floating staircase.
