Hi again!
If the garage is at a completely different level than the home, it's possible that it might not be included in the footprint of the home. I would double check with two mechanisms. First of all you can muscle test and see whether it should be included.
The other thing some people do is create two separate plans, in your case one that includes the garage and one that doesn't. After you have gridded the two options, see which stars fall where and note what has been going on in your life - i.e. if you have a conflict star in the family room for one option, has there been more friction in the family than you might like? If the other grid shows a relationship/collaboration star - have things been pretty amicable?
By tracking what has been going on in the outer world, you can often get a pretty clear picture of what is going on energetically, and hence which plan to use for your feng shui.
