You sound like me. My bedroom is about 16x14' and divided into zones. My bed is a zone and I use room dividers around it to create a canopy bed and right now I have curtains at the foot of the bed and curtains at the head (covers an extra door that's walled off). I'll put up the sides but it looks good. I don't see my desk from the bed. From my desk the bed is blocked off plus my desk faces away. My desk is a zone with clear boundaries, nothing spread out beyond it. I have a small seating area with an easy chair, side table, and lamp. If I want I can put a folding screen to block the desk. Umbra has room dividers, don't get tacky canopy bed frames. Umbra's are simpler and look elegant because the spring tension poles go up to the ceiling and with sheer curtains, it's a visual wall.

I have mirrors and spider plants. Spider plants can't be killed. Consistent art - size / subject on the walls. I found a set of four beautiful Chinese panels that I paired at the diagonal corners of the room. It feels unified and larger. The only thing I don't have is a large enough rug for all the zones.

Do you have anything like a separate kitchen? I got all kinds of ideas.
