Thanks everyone. This is a single story steel framed building. All the interior walls are non-structural. In fact they don't even go all the way up, and the whole house was relatively open before. There is only a patio at the main entrance to the house opposite the kitchen. The other doors in the bedroom area and the laundry room are emergency/utility doors.
I played around with the layout of the two bedroom and office and put a closet taking out of the office area a bit.
It is just me living here for now. I wonder if I shouldn't just do the single master bedroom layout. I planned on putting a murphy bed in the office for house guests which are few and far between.
The building was all open to the steel frame/insulation so I have been adding in ceilings and what not as I go. The walls never went all the way up for circulation, and we never had doors except on the bathroom!
Here's a few pics of the before after I have done so far:
