I'm finishing out the "office/bedroom" in my shop and would like to have a heating unit I can put in the common wall that will allow me to selectively heat one side or the other - or even both sides - my choice.
I have gas available so it doesn't have to be electric.
Any ideas?
the old family home place in Macon had fire places that were open to both rooms ... probably not the solution you're looking for ..
otherwise I got nadda 
Unlkely an in-wall unit exists for this application. It would be a liability to the manufacturer if it was ever installed incorrectly (ie: in a wall that DIDN'T open to the other side).
However, anything with ducting, registers, radiators, or other point of use distribution would work.
In other words, you are looking for a heating system, not a space heater.
Or, you could cut a "window" in the wall and set a space heater in it, and turn it around when you want to heat the other side.
I have considered a central heating unit with a big dump vent into the shop, but that requires climbing upstairs for a manual operation and if I should want to run both sides at the same time there is the balance between the 2 to be considered. I'm sure that after a while I'd learn how far I could open the dump valve, but I was wondering if there was some sort of ready made option that I wasn't aware of.
Zone valve. (or damper)
Can be operated electrically or manually. A manual version with a long chain on it (like a bicycle chain) could be operated from the floor without climbing.
For the more creative, I guess a damper/ zone valve could be pneumatically controlled, or hydraulically controlled, or whatever.

if you did put a heating vent into the shop, you'd also then have to put in a vent to allow the air to return back to the furnace.. do you want all the fumes that are in a shop to be intermingled with the air from the living area- fun stuff like gasoline fumes and carbon monoxide really aren't supposed to get to where you sleep..
I had intended to put the return in the office/bedroom area, but as I think about it now I realize that probably won't solve the problem. If I suck the air out of the living area then it will have to get air from someplace so it will suck air from the shop portion.
I guess I'll have to rig up some sort of fresh air intake which means the air will have to be heated more in the winter so it will be less efficient. I guess positive pressure on the shop is a good thing for getting rid of smells.
My bedroom and bathroom share a common hot air duct. Opposite sides.

You mean getting rid of smells and pushing them directly into the office/ bedroom? 
Or are you trying to keep outside smells from entering the garage? I'm confused.
