Each era added to the previous one something new and distinctive serving development and growth. At present, the importance of this concept has emerged after an increased call to invest in the heritage and re-ernploy it in new attempts after adding to it, thus achieving an architecture that keeps up with progress and development, as manif( Sted in all fields of life. The issue of this paper pointed out the iack of knowledge a bout the crem ive nature of addition, which is connected to the designer in Contemporary Iraqi Architecture Thus; the main goal of this research is to.give the most efficient and :learest image to define this nature. The research has adopted four main steps which cover firstly theoretical study of creative product. Secondly, a comprehensive conceptual framework is built to describe creative nature of addition in architecture (its levels and characteristics). Th rdly, this framework is applied to selected examples of contemporary architecture in Iraq to extract the nature of creative addition.
 In this research we found the- special feature of addition in contempo,ary Iraqi architectural products has been explored becau•se it is a creative and inventive addition with derivative nature at the conceptual and physical levels, by adcpting assembly technique to achieve original and appropriate addition taking into consideration theoretical content and the nature of form elements.
