Closet design/ bedroom closet layout suggestions requested

[Jeff Bridges]

So we've gutted one of our bedroom/office additions in order to apply proper insulation on walls and ceiling. As a result we've had to demo the existing closet and have a chance to redesign. What would you recommend given the space available? See below floor plan. The proposed area for the closet is highlighted below in yellow and the existing closet with the red x will be demolished. I'll be losing 4 inches on the bottom wall due to insulation and framing. So I'll now have a depth of about 20 inches for any new closet along that wall. Contractor proposed building a sliding barn door style closet in the middle with bookshelf/shelving on each side. Is barn door functional or should I go with regular door? Alternatively, I could just make a new closet a bit wider in the same place as the demolished one to make up for loss of depth and keep the space on the right of the closet. Any other suggestions? 

Any recommendations on wiring? We'll be redoing the wiring and adding about 5 receptacles and recessed lights. Anything else we should be considering? I assume if I do shelving, one of them could be wired with power for a TV and a bed could be placed on the top wall facing the shelving/ TV.

Thanks!

You have to be able to have a bar to hang clothes and have them hang completely in the closet. From experience I can tell you that is 22-24 inches. If that entire wall is built ins you could put 24 inches at the other end for hanging stuff, make a TV space in the middle and put shelves where the closet was. Or you could move the room door to make the closet deep enough. Sliding doors are a good option if you are behind another door.  do you need two doors into the room?
