Forget the orientation of the front door only, although in your house the front door entrance is from the south! Use the report to see what certain rooms signify to you and work on the ones that describe qualities that you want or need to trigger. Everyone is different in that sense -- different priorities at different stages of their lives. Find what is essential for you now and work towards a more complete picture of your house. Work with a room and see how it feels to you.
I think the intention of FS isn't necessarily to activate every sector of every room (that would almost certainly be overwhelming), but rather to activate those that are meaningful. I believe in studying the building, looking to see which rooms are activated by which planets in your chart and starting to focus there. It follows the way astrology works, that certain planets are naturally more significant than others in a chart reading. Find the important ones and work with them first.
As your entrance is from the south, what do you see directly in front of you when you enter? That would describe the house and the entry for your energies and wealth. Are there blockages, or do you see through to the outside of the house? Work with what you see.
