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The furniture was quite outdated as it was made almost two decades before Leo Wyatt found it again.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 bounces her back. They manage to swing it open and escape.
In early 2006, the three sisters were trapped in it together while being impersonated by three demons, who used the doll house's magic to transfer the Power of Three to themselves. After escaping it for the second time, Piper blew it up, killing the demons trapped in it.
- The destruction of the dollhouse in Repo Manor and the death of the demons inside it possibly foreshadows the events of Kill Billie: Vol. 2 in which Paige, Phoebe and Christy die when the Manor explodes in a similar manner.
- The doll house is not an exact replica, as it is modeled after the sets (except for the attic). The door on the right side of the house was replaced by the outside of the sunroom.
