Since this is more than a house and is also present in other forms in real-world folklore as recited in the story itself, I propose to rename it to just Carterhaugh
Talk about it here.
Carterhaugh House was a house in Shoreditch. Thomas Laneford thought it was a bit grand for Shoreditch. April MacLean thought that it was brilliant and she hadn't seen it before. It contained a library and a greenhouse. Ram Singh thought it was alien because the greenhouse couldn't fit inside the house. (AUDIO: Gifted)
