Walls are of stone, either rough-cut stones laid in a random pattern, or dressed stones often laid in a herringbone pattern or in flat courses. Most houses are two-story structures, which provide relief from the damp at ground level as well as great views into the distance.
立面以石砌牆，常見亂石砌、人字躺、平砌等形式，多為兩層樓建築，如此可避潮氣，又可遠眺。
