From a small suburban town Dhaka has emerged as a megacity in course of about four centuries. Dhaka is on the verge of a change in its urban character, vertical growth taking the place of horizontal expansion. This change has an obvious effect on the character of the built environment of the city. This study is an attempt to explore Dhaka’s built environment by investigating different areas of the city in respect of population, land use, lot size, ground coverage, site set back, building materials, building height and so on. Finally, by using the 3D map of the selected areas sky view factor (SVF) is calculated in TownScope software. It is revealed that both the population density and the characteristics of built environment vary greatly from one area to another. Furthermore, the SVF differs significantly in the selected areas of the city which can be considered as an indicator of built environment of Dhaka and should be addressed adequately to make environment-friendly city areas.
