Stick frame it and log side it. Less headache, better R-value and the same look as a log structure. I work for a high end custom home builder. We build log, timber and stick framed homes. Plus, hybrids of each. Log homes are not as efficient as stick frame, despite claims. More expensive to build, way more expensive to maintain. Most log structures are a "kit." Even handcrafted structures are built in a yard, disassembled, numbered and trucked to a site to be reassembled. I could go on.... mtmuley
