Abstract. Today, right along with the products marketed and manufactured by the mass production techniques, continuously developing computing and technology have an undeniable impact on customized design, in which the users have a say on the products design and manufacturing. Mass customization is slowly settling down in architectural design concepts as well, like housing which is one of the best areas where users can relect their living habits and preferences. In this study, user centric mass customization based model is developed, which creates housing loor plan combining the user-supplied data with the best possible creations generated by the genetic algorithms.

With- in everyone’s house, there lies the most private ar- eas of its users and these users are attached to their places. Individuals’ expectations from their houses are by satisfying their personal needs and wishes, in- creasing or at least protecting their living standards. Therefore, people are instinctively prone to design and build their own houses. Since the beginning of the twentieth century until now, residential produc- tion is done with the help of industrial products and tools. In this rapidly industrializing of construction era, user participation in design process is neglected. This result in identical buildings that are built with the logic of mass production and using industrial- ized products, and these housings’ failure to fully satisfy every individual residing in these houses is an important problem. Residential design that is orga- nized according to the needs of the user, is inevitable to satisfy users. Mass customization is designed to deliver highly customized products with mass production eiciency (Piller and Kumar, 2006). Mass customization plays a very important role in the usability of the products as in diferent levels of the work like design, manu- facturing and distribution it is always in contact with the users. It is in fact standing out in many ields like
