I love Storybook architecture, so Dan Pauley's whimsical shacks appeal to me.
From Twisted Sifter:
Dan Pauly is a fourth generation wood-working artisan best known for his amazing rustic cabins made from reclaimed wood. The Minnesota-based craftsman builds saunas, sheds, bunkies and outhouses with his signature roof and chimney. Dan, whose great-grandfather emigrated to the US in the late 1800s, built many barns in central Minnesota, some which still stand today.
