Here are some examples of Eichler Homes Scroll down through to see the different styles. Some are pretty dull on the outside.
Oh and as far as being cheaply built most CA homes were. Ours was built with green pine 2x4s that warped so they came and cut them in half and cleated them to straighten them out. Then they put what I call chicken wire and then black tar paper and a thin coat of stucco. We opted to have R1 insulation (because that was all we could afford) otherwise there would have been none.
Google 1134 Hyde Ave, San Jose CA. The only difference in that house now is they replaced the cedar roof. We paid $32,000 in the 1960's for it. Now look at the price.
I may have stayed in a motel in Gatlinsburg, Tn. which was designed by the architect you refer to. The Pine Cliff motel looked like a ship on its top but it was very substantial composed of poured concrete. It did have a lot of windows and we loved staying there.
However, that first picture does not look like one of these homes to me.
