Question

What is the difference between a Pueblo house and an adobe house?

Pueblo describes the building tradition and form. Adobe describes the material the walls are made of. Pueblo refers to the Indigenous communal multi-story stacked-room dwellings of the American Southwest, as at Taos Pueblo and Acoma. Adobe refers to sun-dried earth brick. The two overlap because most traditional Pueblo houses are built from adobe or coursed earth, but the categories are not identical. A modern single-family home in New Mexico can be adobe without being Pueblo — single-story, no terraced massing. Contemporary Pueblo Revival buildings can imitate the Pueblo form using stucco-over-frame without containing any adobe brick at all.
