Cities intrinsically perform their evolution in a rule–based environment through dynamic processes. Even the cities, which developed without any rational planning process, are built with specific building codes. The rule–based framework that is defined by a set of simple building code provides a basis for the emergence of different urban typologies through the history. Necessity for such codes is crucial in order to maintain the inherent integrity (morphological coherence and functional integration) of collective urban form. In the very context of rapid development and transformation, plans and codes have been the basic apparatuses to shape the modern urban environment over the past century. The uncertainties that faced in city development and the complexity of the processes conditioned by the existence of various actors involved (developer, contractor, designer, user and local governments) required the development control systems to define more flexible and responsive coding techniques rather than solely relying on the masterplans performing as static spatial diagrams. This essentially requires a new approach which addresses more bottom–up and incremental applications by code–based control frameworks. On the basis of the principle of controlling overall urban formation on the scale of plot, the emerging paradigm of ‘plot–based urbanism’, in this context, suggests a fruitful basis to develop an alternative methodological approach to urban design. Computational modelling tools run by design algorithms, at that point, suggest a very relevant technical basis to apply the new approach in actual urban context. Generating various compositional patterns via certain geometric components and their constitutional parameters, parametric design basically enables designers to gain a serious control over the complex formations. In the context of urban design, that means the possibility of the complex formation of urban fabric on the multiple interaction of plots in the course of time. The current research, in this framework, is to develop a parametric model to integrate computational design to development control in emerging context of plot-based urbanism. Utilized as the already existing codes of Turkish spatial planning system, the actual building rules are taken as the basic parameters of the plot–based generative formation of urban fabric by the algorithmic model proposed. The model basically aims to invest on the urban contexts like Turkey, where the plot has still a significant role in the reproduction of urban model and to provide a responsive control method to come up with coherent unities within reach diversity of urban form.
