Where did Victor Frankenstein live?

After fleeing Frankenstein's home, he takes to the forest and the mountains, where he says that he lives on berries and roots. Soon he discovers the De Laceys' home, and lives in what I understand to be a small outbuilding attached to the side of the house - possibly a storage shed of some sort. He lives there for about three years. When he follows Frankenstein to Scotland, he presumably lives on one of the Orkney islands near to Frankenstein's own, and upon returning to Switzerland, one can only assume that he lives again in the mountains. By the end of the novel, he is continually travelling, as is Frankenstein, and so both live nowhere.
