Adobe is a building material -- tightly compacted earth, clay, and straw that is hand- or form-shaped into bricks -- and also refers to a primarily residential architectural style found in the southwestern United States and some Spanish speaking countries. Construction methods and composition vary according to climate and local custom. Adobe style homes are influenced by early Pueblo dwellings with adobe walls and flat roofs. Vigas, Spanish for the heavy beams supporting the roof, are often exposed. Latillas, meaning sticks, are often used as infill between the roof beams. Adobe house plans may include Mission style details (stucco walls, arched doorways, and roof parapets) and/or Spanish Colonial Revival elements (red roof tiles, decorative railings, and tiled courtyards). The home designs of prominent New Mexico architect and preservationist John Gaw Meem were especially successful at combining a regional adobe esthetic with modern plans.

Another term that includes adobes is the Pueblo style. Key reference works for New Mexico adobes include Of Earth and Timbers Made: the Architecture of New Mexico, by Bainbridge Bunting, (University of New Mexico Press), and Taos Adobes: Spanish Colonial and Territorial Architecture of the Taos Valley, also by Bunting (University of New Mexico Press).
