A survey on the form-based code approach and its place in urban design

Form-based codes, as a relatively new approach, support the rules of urban planning and design with the aim of achieving efficient public spaces with a location-based approach. In fact, this approach, by considering the contextual characteristics of the urban environment and its landscape, creates codes with the help of planner and designer thinking, which is based on how different types of urban forms are placed in different places. These codes can achieve the best possible layout in order to meet human needs by predicting the environment created by controlling and adjusting the forms. Today, in our country, due to the complexities of urban design, in the field of creating balance and interaction between land use, urban form and location, the need for this approach is felt more than ever. This article has been compiled with the aim of becoming more familiar with the process of production and regulation of urban design codes with emphasis on local, cultural, social and historical conditions. Therefore, it has tried to discuss the approach of form-based codes through the concept, process and its components and briefly address some of the challenges facing this concept.
