Who knows architecture?

All these videos of micro-living gives me the idea that it is feasible to build a bonus room on a second floor of a ranch house. It doesn't have to be huge, but something that is heavily functional. i.e., if it's a guest bedroom, the trick is to put the murphy bed in to make the place useable when you don't need it. Like a writing room with a view.

Does anyone have photos of plans where someone built upward on a house that was originally a one floor plan?
