Many members of the family were respected religious scholars. At the same time, they were among the regions first Westernizing elite and contributed to public works projects in the name of modernization. Their palaces remain as testament to both their affluence and the complex identity of the modernizing elite of the colonial period. Palaces financed by the al-Kafs and other families were executed in the stylistic idioms they encountered in British India and Southeast Asia. Consequently, the palaces include examples of Mughal, British Colonial, Art Nouveau, Deco, Rococo, Neo-Classical, and Modernist styles unparalleled in Yemen. While these foreign decorative styles were incorporated into the Tarimi architectural idiom, traditional Hadhrami construction techniques based on the thousand-year-old traditions of unfired mud brick and lime plasters served as the primary methods for executing these buildings.
