Abstract
The urban context of Egypt is rich in heritage conservation districts and valuable listed buildings. However, these districts are always in a state of change due to new infill buildings.
The infill buildings -specifically their facades- affect the total urban character in a positive or negative way based on the design of the façade. These designs are usually disappointing in the absence of clear and objective guidelines that should direct these new designs.
In addition, design review committees was not enough to judge and evaluate the compatibility of new infill facades, because they depend only on professionals ignoring the other stakeholders that should govern the urban character specially normal lay persons.
In this research, the collected layperson impressions are compared to professionals’ views and a significant difference in judgement is proved between the two groups.
Additionally, new building facades in a historical settlement in Egypt are investigated, using modern entropy approach. Derived from physics and information science, the entropy method is used to judge visual chaos in a systematic scientifical way. Then a correlation analysis is performed to compare entropy of façade attributes to peoples’ perceived compatibility of the infill building to its context. The façade attributes tested here are building scale, setting, solid /void structure, rhythm, colors and materials.
