Throughout the ages, the aesthetics of ornamentation have always been contingent, but ones that have withstand the test of time are those that are of classical or ancient period, such as the Islamic facades of the Al’hambra or the structural layering of Japanese temples. One of the reason of why these architectural ornamentations are beautiful to us lies in its qualities - repetition and variation. For us, the repetition of elements defines laws that , to us, governs how each parts is to be, helping us to recognize the pattern and therefore understand it. Variation, on the other hand, gives a sense of change and so makes the pattern more interesting to look at. Take the Japanese temple as an example, each roof unit decreases in size as it multiplies around and down from its original unit. Because such aesthetics are not learned, we can say that this is an innate quality that everyone of us is born with.
These ‘innate’ beauty can be found in nature, most predominantly in plant phyllotaxis - the arrangement of plant leaves or seeds on the stem. Most common are the opposite, alternate (spiral) and whorled arrangements, all of which give a variated but understandable pattern that share similar characteristic as the Japanese temple - repetition and variation. The structure of plant phyllotaxis is widely used in contemporary architecture, with application ranging from infrastructural systems to detail arrangements of architectural components. In a case study which applies the natural systems to parametric urbanism, the architect have distributed each housing unit according to a phyllotaxis model that refers to the distribution of seeds on the surface of the plants, with each seed seed-sphere corresponding to one housing unit. In another example, the shadow pavilion by PLY architects, the surface of the pavilion is based on the geodesic arrangement of spores on plant surface which is converted into apertures (thus the name “shadow pavilion”) patterns.
By using natural systems as a basis for architectural design, the designer can tap into our instinct of what is or what is not pleasant, and therefore will be able to phenomenologically and empirically control the spaces that he or she creates.
