Tradition-led regeneration of contemporary neighbourhoods’ spatial structures: A case study of Tehran City, Iran

Over the past decades, modernisation has been viewed by some as one of the greatest dangers to urban life, having altered neighbourhoods dramatically. The most significant problem is the destruction of traditional neighbourhoods. The authors propose that a viable solution to this problem is to regenerate the spatial structure of contemporary neighbourhoods using traditional styles and elements. The transition from traditional to modern society has created numerous styles and challenges in the Iranian urban landscape system; in particular, the city of Tehran is experiencing considerable changes in terms of visual appeal and connection to the environment. In this paper, the principles and models for traditional neighbourhoods in the city of Tehran were studied and grouped into three categories: form, function and meaning, as a guide to regenerate the spatial structure of contemporary neighbourhoods. Three neighbourhoods from different eras were selected: Oudlajan, Shahrara and Shahid Bagheri, from the Qajar period (1789–1925), the Pahlavi era (1925–79) and the modern era, respectively. Spatial models were extracted by analysing the traditional urban design of the city of Tehran in three time periods alongside patterns and principles used in the regeneration process. Following this, criteria and principles were proposed for tradition-led regeneration of the spatial structures of contemporary neighbourhoods by form (physical form system/urban landscape), function (land use system and activity/movement and access system) and meaning/perception (frameworks for public spaces).
