It sounds as though the house move has really unsettled her and she still doesn't feel 'at home' in the new house. Perhaps you need to go back to treating her as a new puppy for a few weeks till she settles. Her chewing is most likely to be a nervous 'displacement activity' to try to calm herself. If you leave her with a stuffed Kong or similar when you go out, and restrict her access to a smaller area (using puppy panels or similar), she will probably get out of the habit. She's not 'punishing you' - dogs don't think like that!
Good luck.
