We can determine the impacts of a proposal on the adjacent residential buildings and their private open space. A shadow diagram allows us to view and calculate the amount of shadow cast by the proposed development. It contributes in determining the shading effect of the adjacent structures as well as those casts by the proposed structure which helps in shaping the sustainability of the development.
