Which house style features flat roofs and earth-toned stucco walls influenced by Native American and Spanish Colonial design?

The house style characterized by flat roofs and earth-toned stucco walls, heavily influenced by Native American and Spanish Colonial design, is indeed Pueblo. This architectural style is emblematic of the Southwestern United States and is distinguished by its use of natural materials and integration with the landscape. The flat roofs often serve practical purposes, allowing for rainwater collection and providing shaded outdoor spaces. The earth-toned stucco walls harmonize with the desert terrain, reflecting the region's natural colors.

Pueblo architecture draws upon the cultural aesthetics of the Indigenous peoples of the area, incorporating elements that are both functional and symbolic. This style often features rounded corners and simple geometric forms, adding to its unique charm. By focusing on materials and designs that are in sync with the environment, Pueblo homes exemplify a thoughtful approach to architecture that has stood the test of time.

Other styles, like Colonial, Prairie, and Ranch, diverge significantly in design influences, roof styles, and building materials, making them inappropriate choices for this question.
