Floorplan of Three's Company Apartment

I plan on adding an addition onto my big barn, an apt to rent out. The barn is ten feet tall on the lower level, and thirty feet long. I thought it would be cool to build a threes company apt on the side of it. Look at the blueprint and picture the lowest edge being the barn wall, the wall of the apt you never see in the show. I was looking for a plan with measurements, but not finding any. Then I had the idea I can measure the beds or fridge in this  plan and figure it from that, those sizes are universal. If I do the project, I might just rent my house out and live in the apt myself. I can pretend to be Jack. I just need a couple of hot girls to make the thing complete.
