The purpose of this paper is to demonstrate the relation between design variations of building parts and building system configurations at building modification. The effects of building system configuration upon the design variations of building elements were analyzed based on a newly developed concept named “structural diagram” of building.
This analysis revealed some prerequisites of adaptable building system as follows: it is important to allot different building sub-performances to different building elements to increase variations of partial design, and it is also important to draw up any spatial rules to coordinate building elements to which allotted different building sub-performances.
