Hi, and welcome to Pet Talk (or as others around here refer to it, PT).

How long has it been since the move? Maybe given a little more time, he will get used to the new house. Just stay calm, and don't try to force him into those areas of the house, but when he goes there to start checking them out, reward/praise/treat/etc. Could it have something to do with carpeted areas? It sounds like he avoids places that are hard floors, and the places he likes usually have carpet. Maybe he's just got 'cold feet', (pun fully intended) LOL
