h planners may continue to wish for a world like it existed earlier where they did not have such numerous factors to take into account before even beginning to plan any town, but such a probability has been closed on the human civilization forever. What remains now to be done is to ensure that whatever planning is now being done in urban areas all over the world, they are established on sustainable grounds. The only way to find out which patterns of planning towns will prove to be sustainable however, is to study the already evolved planning techniques by the developed world and compare between them what should be the best mode for developing towns when it comes to countries which are presently undergoing urbanization. The issue being addressed in this paper is to critically examine and compare urban planning cultures in developed and developing countries and discuss how such cultures have evolved or been adapted to the different development planning challenges being faced in those countries.
Britain- the first of the European Union countries to become industrialised, had only around 3% of its labour force concerned with the agricultural activities, while almost 80% of its population had become urban by the year it had joined EU that is the year of 1973. Therefore for countries like Britain and even the United Sates or Japan for that matter almost any kind of town planning is mostly urban town planning. The change in patterns of planning however has occurred with time in countries like Great Britain. For instance, the difference between the local town and country planning introduced by the historic Town and Country Planning Act of 1947 and the system which replaced to under the Town and Country Planning Act of 1968 is that of details (Taylor 1998). It was argued in the 1960s that planning should not be focussed on minute details in fact it should be based on generalised and diagrammatic picture of the spatial distributions at any point of time, only filling in
