Because we have billions of trees.
In the state of Alaska each resident is permitted to take a certain number of board feet (so many trees) to build themselves a home. Forget the number but it's enough to build a couple of large three bedroom homes. Not bad considering it's free. Anyway, if built properly wooden homes are not only sturdy but beautiful.
It's neat especially considering we have a large amount of yellow and red ceder. I'll definetly utilize this some time within the next few years. Yes log cabins...very large ones at that. Someday....
My neighbor built his with the styrofoam/concrete mouldings. They're leaps and bounds stronger than the stickbuilt homes in terms of wind resistance (I think I read that they'll withstand 2x4s @ 80-90MPH...can anyone confirm that?). Very nice for this part of the country. I don't know the price difference....I'd have to ask my dad.
