In "Formal Synthesis Notes" published in 1964, traditional architectural design is compared with modern architecture, Christopher Alexander distinguishes between two design cultures, "unconscious design" and "conscious design" . "Unconscious design" (or "process-based" design) involves the use of traditional building methods where designers unconsciously work on forms and directly interact with forms in complex two-way. Interaction between the world itself. Design rules and solutions are basically not written and are informal. The same format is done many times without questioning why and designers need only learn patterns. They know that a particular design element is good, but you do not need to understand why that is good.
Islamic philosophy has no major impact on the modern design era of Germany, Northern Europe, and Japan from the perspective of architecture and products. However, this does not constrain detailed research on how to compare the two aspects of the design, and the results proved to be more realistic than the comparison. This is because traditional Muslims strongly demand special research on the details of aesthetic projects, not for beautification of material or secular values. An example of the lifestyle image of the Prophet Muhammad is consistent with the various Hadith's design concepts described above for his life. With this in mind, the Qur'an and Muslim are required to develop sustainable production to the craftsmanship of products, in order to draw out the conclusion that the most Islamic design of the last century comes from Germany, Northern Europe, , Early on living and minimalism investment. When Plato respects geometry, modern design is a complex and simple geometry application.
