Adobe blocks are a building material made from earth and organic materials typically found on site. Clay and sand is mixed with water. Often straw or grass is included to help bind everything together. The mixture is placed into wooden molds to form blocks. Once dried by the sun, the blocks are used to build thick walls. A layer of mud plaster, lime plaster, or whitewash is added on the outside and inside to protect the adobe blocks from water, weather, and other damage.
The Michael White Adobe is constructed out of two different size adobe blocks. The walls of the one-room north wing have 12-inch blocks. The two-room south side has thicker walls constructed of 22-inch blocks.
