Splitting A Bedroom Into Two Ideas. You'll need a new doorway in an existing wall (or have an awkward access one room through another arrangement). What gives me the idea is there is two windows in this bedroom so if i split, the extra room will have its own window.

Two windows already in place. Using a fold down dining table to create two rooms from one. Why not place a toilet in the bedroom to let the same space be used for 2 purposes.
