This transformation came along with some negativities, which gave rise to the concept of sustainability in urban form. In this regard, the current study aimed to assess and validate the reciprocal relationship between urban morphology and sustainable urban form. This study proposes a conceptual model which integrates and presents the holistic correlation between sustainable urban form and urban morphology, by using qualitative grounded theory as the research methodology. The model was developed by introducing analytical tools to evaluate sustainability, along with integrating typo- morphology and the concept of scale hierarchy. The findings of this study reveal that every single component of sustainable urban form interacts significantly with the typo-morphology approach. Consequently, the outcomes help urban planners to get more informed decisions about the geometric analysis of urban morphology from a sustainability point of view. Keywords: urban morphology; sustainable urban form; typo-morphology; concept of scale hierarchy 1. Introduction The emergence of the notion of sustainable development has created a platform to enable a public debate on the form of cities to take place [1]. It has subsequently motivated researchers, decision-makers, and urban planners in related disciplines to seek sustainable forms of development that are beneficial for the built environment. Considering this fact, morphological analysis of urban tissue reveals the logic of urban transformation, urban morphology can thus be a valuable implement to achieve sustainable urban form [2,3]. Although much research has been carried out on the topic of “urban sustainability” and “urban morphology”, there seems to be a substantial gap in the study of the mutual relationship between the two [4–8]. This study tries to focus on the relations between urban morphology (UM) and a sustainable urban form (SUF). Accordingly, this study aims to propose a model to evaluate the relationship between SUF and UM. The analytical tools derived from this relationship can be used as an assessment technique. Since the issue of the urban context is a continuous multi-layered process, it is vital to formulate a defined scale hierarch to streamline the process of the assessment. A strong spatial hierarchy is significant to determine the contribution between the important aspects of urban structure and the analytical tools of the research. Accordingly, the study introduces a spatially hierarchal structure, by integrating typo-morphology and the concept of scale hierarchy concerning Kropf’s taxonomy [6]. Therefore, the following research question has been considered as the main concern of the research. • What is the relationship between urban morphology (UM) and sustainable urban form (SUF)?
