I have read that bedroom over garage has bad fengshui,what if the room is used as an occasional sitting room?

Fengshui is about common sense most of the time. If there's any 'bad' fengshui, it's because it could be noisy, and, if there's any bad fumes, it could escape up into the bedroom. Remember that fengshui was thought up long ago, before there were any cars or garages around.|||If you park the car sideways in the garage this gets rid of the negativity. You may need to saw off a couple of feet either end of the car but it'll be worth it for all the positivity.|||you don't believe that feng shui b*llocks do you?|||Oh really! do you genuinely believe this? The only problem I can see is killing yourself with carbon monoxide from a running vehicle engine beneath a badly made wooden floor/ceiling. Just use the room for whatever is convenient to your lifestyle and leave the fengshui to those who have more money than sense....|||Doesn't matter what you use the room for, it's just bad. Use it for storage.
