Your cat is probably feeling insecure in the new house. He wants to make the place feel more like home by scratching everything. Having extra scratchy places is a very good idea. Try putting double sided tape on places where you don't want him to scratch and placing a scratching post near the problem areas.
Some cats feel more comfortable when things smell like them. You could try placing some things that smell like your kitty (kitty beds, pillows, litter boxes etc) around the apartment. Feliway might also help your cat to chill out a bit.
What is a normal day for your cat? What is your daily routine like?
I know how it feels when you get completely frustrated at an animal but just remember that he ain't doing it just to be an asshole.
