Self-U-Store
From Tardis Wiki, the free Doctor Who reference
Self-U-Store was a storage unit in Swindon. It was used by customers for the storage of various items such as books and household furnishings, including furniture, carpets and exercise bikes.
In particular, Storage Unit Seven was the unit in which Agnes Havisham was kept cryogenically frozen.
Self-U-Store was located on an industrial estate which had formerly been a private airstrip, and before that an air force base. (PROSE: Risk Assessment)
