My neighbor's brother built and lived on one years ago.. From the video he sent her it was one of the most beautiful houses I have ever seen. She visited him in the winters and said the house was great to stay in. I think they are very well insulated, you have huge logs as barrier walls for the outside. You can also heat it the way you want. I know one person that heats their whole house with just a wood stove in the family room.
When we first were planning our move here there was a pretty log home for sale, the real estate agent sent me tons of pictures. I loved it. The sad part it was on a dead end street with a house with too many construction trucks parked there all the time.
I know there are some good log home magazines that give you tons of information on log homes. I have subscribed to them ages ago . You Might be able to find them at Barnes And noble book store.
I would definitely buy a log home if I had the chance. Good luck.
Do you have pictures of the home.?
