ABSTRACT
A typical method of the ‘additive’ or ‘constructive’ kind starts with an empty site or empty ‘floor plane’, and builds up a low cost layout, one activity or one room at a time. The number of ways of arranging one activity in one location is one; of arranging two activities in two locations, two. Every ‘additive’ procedure has two essential features. The first is some kind of spatial framework within which the plan is assembled. The second requirement is for some criterion by which to decide in what order the activities should be placed, one after another, in the plan. A series of checks made during the program’s run are designed to control the positioning of activities and their associated extra areas, such that the circulation spaces should connect into continuous corridors, and that the external ‘light and view’ areas should not become enclosed or blocked by other units.
