The rule system is defined for the purposes of this paper as the underlying system of rules and codes which Islamic culture has established for itself to guide and control societal activities, including decisions and activities related to design and construction.

Within each particular region, the local customs are normally a part of the governing rule system. The author argues for the revival and adaptation of the traditional rule system by maintaining its positive attributes, and incorporating modern technology and changes in the lifestyles of the people in specific localities. He suggests a policy for the governments of the Maghrib countries – Tunisia, Algeria, Morocco – for initiating the process of reviving the rule system and outlines the necessary steps for implementing such a policy.
