Steve, your existing log cabin, how thick are the logs? That site you linked to reckons 44mm logs are adequate for year round use as living/office etc. How's yours in winter?
I intend keeping one or two oil filled radiators on at low setting during winter months, like a did with old outbuilding before we moved (that was block and brick with cavity though).
