The Miwok people lived in various types of houses, primarily in thatched-roof structures known as "kitchen houses" or "sweat houses." These were typically dome-shaped, made from wooden frames and covered with grass, reeds, or bark. At missions, they adapted to larger, more permanent structures that were often built by Spanish missionaries, which were more European in style and design. These changes reflected the influence of the missionaries and the shift in their lifestyle due to colonization.
