When I lived in North Dakota I built an insulated dog house similar to yours with a pet door on it. Made the roof to come off for cleaning, etc.. I also put a light bulb in it for heat when it was relly cold. 30 below zero and it would still be in the 40's in the dog house. Worked really well for me and I felt better about leaving the dog outside. He seemed to like it.
