Received: 10 May 2019 Accepted: 13 March 2020 In the past, Jordanian cities were just small centers, with no planning systems. Today, many of these cities have expanded in response to emergency urbanization and ongoing political crises. The resulting development has irreversibly modified the urban landscape. Studies of urban conditions in Jordanian cities, particularly, Irbid, are key to understanding how rapid growth has altered its architectural and urban landscape. This paper focuses on the problem of urban regeneration and requalification to identify the variables driving informal development in Irbid. Understanding the real factors, as illegal and abusive land use, at play versus unnatural development where classical approaches are not suitable for understanding the problem. Highlighting policies, strategies, and tools needed to identify transformation trends of cities like Irbid, to produce hypothesis of sustainable and suitable development. Results show that to propose innovative hypothesis we must first research evolution mechanisms and their transformation effects. Using tools that define conditions of under developing that govern transformations in our case study. A spatial modelling would be an interpretation model that combines effects and causes, of the cited under developing situation in future projection of sustainable development. The proposed spatial modelling, “Integral Planning Model” (IPM), throw investigations and interviews and simulations try to build a parametric matrix processing able to help the planners and policy makers to put up suitable strategies.
