The concepts of ‘city singularity’ and ‘smartness’ were utilised as a guide for writing this article, along with other elements, such as personality, identity, and character. We used a descriptive-analytical research methodology. According to our scoping review, urban form and everyday life have much in common. This study identified 13 factors in four categories to analyse the urban form of Egypt’s New Administrative Capital City, while ignoring lifestyle, since the city is still under construction. A framework for developing the singularity of capital cities is presented in our results, as a means of increasing the city’s singularity across its urban forms. By applying the four keys and the factors of singularity, this article concludes with a framework for enhancing the urban structure of smart cities. It was also suggested that the smart city concept could provide new directions for designing unique capital cities worldwide.
