The Doll House was an exact mini replica of the Halliwell Manor created by Grams when Prue, Piper and Phoebe were children. Although at the time Piper assumed she made it herself, she really did it through magic. The furniture was quite outdated as it was made almost two decades before Leo Wyatt found it again. In 2005, Piper and Leo were trapped in it by Wyatt when he thought they needed protection from danger. Piper tried to blast open the window, but a Force Field around it bounced her back.
