In architectural drawings some conventional symbols are used to represent the various parts of the design or construction. For example, a red pattern can be adopted to highlight a sectioned wall, a wavy line can represent the thermic insulation, a double line with an internal hatch means a waterproofing membrane, and so on. I tried to carry these symbols on organic forms, mixing the two languages. The architectural symbol drags behind part of the original meaning. In his new capacity will evoke the idea of a protective skin, a shell, an inner layer of fat.
