This dissertation deals, firstly, with the nature of zoning and development controls, and their relationship to the planning process. From this broad overview the emphasis changes to deal more specifically with how these regulations affect flat development; and to look at the Durban Town Planning Scheme area of Berea North in particular. The zoning and dimensional regulations are examined in detail, along with the flat development that has taken place in Berea North as a result of the implementation of these regulations. An evaluation of the Berea North regulations follows, which covers four aspects, namely, evaluation of the planning process, the goals, the regulations, and the resultant development. This leads into an examination of some alternative systems of Development Control, with the suggestion that these be considered for implementation in Durban. The conclusions arrived at in this study are that zoning and development controls are essential elements of planning; that they are both part of the Development Control system; that there is strong justification for controlling flat development; that the methods for controlling flat development in Berea North are neither efficient nor sufficient; and that there are alternative and more successful ways of controlling flat development. / Thesis (M.T.R.P.)-University of Natal, Durban, 1978.
