In a physical sense, many people think of the city’s open areas as the spaces between the constructed areas. From this point of view, they are the mere by-products of construction, because in themselves they have not been articulated, nor are they at all independent. The basis for understanding them resides in the built-boundaries, the edges built according to the way a given designer of space sees the end result or perhaps only in order to facilitate or enable anything whatsoever in which the people take pleasure or delight. But in each case these are spaces of perception, communication and human interaction, stages necessary for the understanding of the built-up area and the way people function in it.
