The Cotton house was the main location for Hellraiser and is briefly seen in Hellbound: Hellraiser II.
The house has 3 floors. It has an attic, a living room, and at least 3 other bedrooms. It is located on 55 Ludovico Place, Cricklewood, London, England.
Frank Cotton originally lived there, and ended up solving the puzzle box there. Years later, his brother Larry and wife Julia moved in the house, and Frank was torn apart yet again in the same room, after the cenobites found out he escaped, and Frank confessed.
At the end of the original Hellraiser, the walls in the house collapses, and in Hellbound: Hellraiser II, the police investigate what happened there.
