I looked into building small rooms for offices with necessities like that. I even considered if you could use old containers and build it out of them, but there is problem with protecting against rain, wind and the lack of windows.

My old dorm-room had this layout: http://i.imgur.com/FB3PGYT.jpg which would work great for a two person office.

I do like the idea with having showers available.
