This is what the Dover basement could have turned out to be. In this diagram, I decreased the size of the project room (by 2-1/2 feet on the right), increased the size of the bedroom (by adding that same amount to the left). I then moved the door of the storage room to be next to the bedroom window, allowing the bed to be placed in the southeast corner.
Not sure whether I like the project room being smaller – it looks like I could have compromised by moving the partiton wall back to where it was (i.e., 2-1/2 feet to the right, but keeping the clothes closet the current size in this diagram). I also added the sink and cabinets to the project room.
