What is the purpose of using stucco in building design?

Using stucco in building design primarily serves the purpose of creating a decorative outer finish. Stucco is a versatile finishing material that is applied to walls and ceilings to enhance aesthetic appeal while also providing a level of protection against the elements. It allows architects and designers to achieve various textures and colors, contributing to the overall style of a building.

While stucco can offer some degree of thermal mass, its primary role in the context of decorative design makes it more notable for its visual impact rather than its insulation properties or cost-efficiency. In terms of structural support, stucco does not function as a structural element but rather as a cladding material applied over existing structures. Therefore, its significance lies in the enhancement of a building's appearance and not in thermal insulation, cost reduction, or structural support.
