I have an existing home with an unfinsihed room over the garage. It is partially framed and has electric and plumbing (stubbed up). I would like to finish it, but am having trouble deciding on the final layout. As a minimum, what I would like is to frame in a closet and bathroom (currently not framed), while maintaining access to the adjacent room which is also unfinished. Also, if possible I would like the bathroom to be accessed from either room. Any ideas with the layout would be appreciated.

I have attached a rough copy of the floor plan to play with. The bonus room will be used primarily as a play room / entertainment room /potential bedroom. The adjacent room will be used as a craftroom / potential bedroom. I would also like if possible to maintain the half wall. Please feel free to make any changes and/or suggestions on the layout.
