Abstract: Carrying capacity can significantly affect both the density and heights of buildings in a particular area. While every country has its own approach to achieving equilibrium between building density and height, poor planning and violation of building height regulations can have a negative impact on urban structure and form. This paper presents a model that predicts the degree to which a new building construction affects urban landscape and density. The required parameters for the model were determined using the Analytic Hierarchy Process (AHP) and Delphi methods.The model produced rapid and accurate results with sample data for a medium-size city in Isfahan province, Iran which were then visually validated using three-dimensional visualisation in GIS environment. The model has the potential to facilitate the maintenance of equilibrium between building height and density. It can also assist to identify and prevent some violations of building height regulations in rapidly growing cities.
