I recently finished making a website for SunDog Natural Builders! Kirk "Donkey" Mobert and Bryan Burnoski are the dudes I worked with at Cob Cottage Company and again in Point Arena, CA. They are extremely knowledgable and each has their own way of approaching the same problem (and building), giving you a very comprehensive experience. Neither one is hung up on traditions either, and will usually do something experimental to whatever it is they are working on. Their workshops are very educational and always geared toward the most appropriate and efficient solution; with plenty of room for creativity, of course!
In their 9 day course they currently teach, you will learn all of the essentials taught in the 3 week long "$1,000 House" workshop and achieve the same finished product: a teeny cob cottage from roof to foundation!
I just can't say enough good things about these guys and I'm beyond glad to have had my introduction to natural building be with them. Anyway, enough promo talk, check out their new website!
