How are houses in low rainfall regions made?

Houses in low rainfall regions are often constructed using materials that can withstand dry conditions, such as adobe, stone, or concrete, which provide thermal mass to help regulate indoor temperatures. Designs typically feature sloped roofs to facilitate runoff during rare rain events, while overhangs provide shade and protect walls from moisture. Additionally, homes may incorporate passive cooling techniques, such as natural ventilation and strategic placement of Windows, to enhance comfort in arid environments. Landscaping often includes drought-resistant plants to minimize water usage.
