The First Floor

1. Since the ceiling is balanced across a wooden beam, you can think of the ceiling as a see-saw of sorts.
2. If you could tip the ceiling down in one half of the crawlspace, it would effectively raise the ceiling in the other half.
3. First, you'll need to remove one of the pillars, since they're supporting the ceiling. See the next question for advice on how to go about doing that.
4. Then you'll have to redistribute the weight of the ceiling so that it presses down on the end of the ceiling from which you've removed the pillar.
5. Push the piano so that it rests over the end of the crawlspace from which you've removed a pillar. (You'll probably need to push it twice in the correct direction.) Doing this will tip the ceiling of the crawlspace.
