Just bought 1.4 acres in mid-Wisconsin. Want to build 3K to 4K sq ft ranch style log home. Like Heartbuilt and Hiawatha 12” swedish cope log homes but not sure about which wood to use. Choices are Norway Pine, White Pine or Engelmann Spruce. Just based on wood which would you recommend? Heartbuilt does not seem to chink. Is it always required or recommended?
