This is my favorite tankhouse in Mendocino, California.. The carpenter used groupings of varied shingles. There are several courses of pointed shingles, several more of straight and then several that feature half-rounds. Most of the Mendocino tankhouses are built from redwood and left unpainted. Their age plus the salt air from the Pacific Ocean have turned the old wood to a beautiful silvery gray color. This group of buildings is arranged around some sort of courtyard or garden. A few years after doing this drawing, I walked by and noted a young couple cleaning the tankhouse as if preparing it to be a commercial establishment.
