Here is the homestead of The Firefly Family. This is where most torture takes place. The house consists of several floors including the basement, first floor, second floor, and the attic. Also on the grounds of the farmhouse are shed buildings where additional pain is resident. The shed around back houses where capture cages are stored to with hold kidnapped victims.
In House of 1000 corpses, the house is a house that looks in relatively good condition.
But in The Devil's Rejects it is shown as a "old decaying farmhouse"
