You could take a flat piece of cardboard to use as a base and secure it with a hot glue gun.

You can cover the house in a layer of Mod Podge. That should protect the paint.

Yes, but this should not be your hamster's primary home. Think of it as being more like a playhouse. Hamsters will likely chew on -- and maybe even through -- the cardboard too.

You can use poster board, but it won't be as strong and sturdy as cardboard.

Using a bigger box of cardboard should do the trick. Make everything bigger, like the windows and door. A box that once held a refrigerator or similar large appliance would be perfect; just ask a local store to keep one back for you.
