Gravestone House was a building built right on the edge of a graveyard that lay across Jim's estate. It looked just as run down as the graveyard and was covered in moss and ivy. It was the home of Ivy Henson. When a terraforming device transformed the graveyard into a swampy forest, skeletons rose from the ground, chasing the Tenth Doctor, Rose, Jim and Raj into the house, where they attempted to barricade the entrance. When the Doctor realised the skeletons were actually a maintenance crew who wanted to repair the terraforming device's damage, he handed the device to them, reversing the damage and rejuvenating both Miss Henson and the house.
