Traditional stone buildings in the Asir region retain one of their most prominent aesthetic elements: 'al-Marw,' the shiny white stone that has for decades been a distinctive feature in the decoration of house facades, embodying the skill of the Asiri builder in utilizing local environmental elements to produce architecture that blends function with beauty.

Builders in the past relied on collecting 'al-Marw' stones from mountainous areas, then breaking them into small pieces carefully arranged within stone facades to form geometric decorative units that adorn doors and windows, extending to the tops of buildings in patterns varying between triangles, squares, and vertical and horizontal lines, giving the building a distinctive visual contrast between the whiteness of al-Marw and the dark color of the stones.
