They are independent apartments situated a few feet apart in a group of around 20 structures. They are roughly the size of a medium size trailer home. But the interesting aspect of the buildings is the thick stucco on the outside walls. The flat roofs are also somewhat different. The thick stucco gives the buildings the distinct appearance of being adobe.
An adobe structure is usually defined as being made out of natural building material made from sand, clay, water, and some kind of fibrous or organic material (sticks, straw, and/or manure). These buildings look very adobe indeed. The big concrete stucco walls also add to the adobe quality.
The buildings do look old. They must have been built in the fifties or sixties. Maybe earlier. It would be a great place to live if the rent wouldn’t be too high (maybe they are condos), because you would never hear your neighbour banging things or playing loud music.
