This paper analyses parametric modelling in connection with the Form-based Code (FBC) methodology to support continuous design in an urban scale. FBC is an approach to optimize conventional zoning regulations and has been implemented by a number of cities. Akin to a utopian urban design solution, we argue that the FBC is crucial to develop main objectives, characteristics, trends and impacts in a design process systematically and logically. Zoning emphasizes excessively on land use and intensity control, however, FBC promotes to (re-) create and predict urban-rural environments through controlling forms. FBC is developing and offers opportunities for flexible coding processes, adjustment of density and seamless public participation. Parametric modelling, being rule based, is a significant step towards a continuous urban design creating a mechanism for FBC. This paper presents a framework to connect parametric modelling with FBC processes, and how parametric modelling methodologies allow the form-based coding processes to be more impeccable hence being more appropriate in the process of continuous design flow.
