An adobe mission in California; the texture is wonderful. I don't know if that's lime plaster or not.

An earth-bermed soddie in South Dakota on the edge of the Badlands. It has wood siding. Er, facing. Cladding. Whatever.

The first cob building I ever saw, courtesy Ann Edminster. It's in California, in somebody's backyard. Cob, cob, cob.

Cob bench in the garden in front of their house. I'd guess it's been there five or six years, and is weathering beautifully. The creek is barely visible through the plants on the right side of the picture.
