In this episode at the beginning we notice that the windows of the attic are blown out and shattered to pieces, but at the end of the episode when the hollow destroys the house, for the instant that we see the attic as it explodes, the windows are all intact. And the book of shadows is not in the attic at the time the house explodes, earlier in the episode, they establish that it has been left in Pheobe's condo, so if anyone wondered why Piper still had her powers when the house was destroyed,because their powers are tied to the book, it was because the book was not destroyed, some people have asked this before, just to clarify for those of you that did not know.
