Study of morphological transformation in planned residential areas of Dhaka city

Abstract

Cities are in a continuous process of change and readjustment of its different parts, which are spontaneously developed or deliberatively planned under socio-economic and political condition in different time period. With an outward expansion, the present Dhaka City within the course of ,time expanded more than six times bigger than the Dhaka of fifties. Over the history, the different parts of Dhaka have undergone various physical evolutions and functional transformation in order to accommodate changing economic needs, socio-cultural values, and spatial conditions. Within this framework, the planned residential areas of Dhaka city, which are deliberately planned for residential purpose, have experienced a morphological transformation of their different element with a minor changed in the spatial layout. It is observed that in spite of several controls, the planned residential areas of Dhaka city have undergone morphological changes to adapt to the community need, which has lead from a need to meet the demand of the growing population. As a result, the planned residential area tends to become transformed into an unplanned state in relation to their physical layout and distribution of non-residential function. The aim of this thesis is to find out the spatial logic of morphological transformation in planned residential areas of Dhaka city. In this research, Dhanmondi, Gulshan, and Banani Residential area are selected here as a representative cases to investigate the type and characteristics of morphological element of planned residential area and to reveal the relative caus,e of morphological transformation. The findings will show that, there is a systematic relationship between spatial structure of the area and the land-use transformation with the changing spatial pattern of the city itself
