Think I'd consider penning a safe area for him before your house becomes a pile of matchsticks!!!
Oscar has wrecked one of my sofas, but I've penned that off now ~(bit late, I know!), and he digs the corners in the room, but I've put the small cheap mats in the corners which has stopped him.
If he started chewing dining chairs etc then I'd have to pen him in.
Not sure what else you can do!! Hope someone comes along with some good ideas.
