Parametric design is a new approach to architectural design based on the concept of parameters. It utilises parameters to set relations between design elements in order to define a range of formal alternatives. In this sense, parametric design provides great opportunities for architects to engineer the design process more efficiently; yet its novelty generates some challenges for architectural practitioners. The aim of this research is to explore the position of parametric design in contemporary architectural practices, identifying its advantages and disadvantages in comparison with traditional computer-aided design (CAD). Specifically, the research will compare the theoretical knowledge and the statements made by theorists and scholars of parametric design to the statements of practicing architects benefitting from the parametric approach. This aim is achieved through three thematic parts. The first part investigates the design process through two points of view, focusing on the notions of ‘role’ and ‘driver’. The second part identifies the position of parametric design in practice, specifically focusing on whether it is a style or just a set of techniques. Finally, the third part explores the advantages and disadvantages of parametric design and its distinctions in comparison to traditional CAD and Building Information Modelling (BIM). The research uses the qualitative method based on semi-structured interviews with practicing architects. It also benefits from a two-page questionnaire, which is carried out to get some detailed and specific data regarding the parametric realm. The outcome of this research shows that, in spite of theoretical statements suggesting otherwise, parametric design can be undertaken without the use of computer programs. Software packages facilitate the process of design. Furthermore, the interviews conducted with architects in practice show that they believe in parametric design as a set of techniques. They do not recognise the new style ‘parametricism’. 4 Declaration No portion of the work referred to in this thesis has been submitted in support of an application for another degree of qualification of this or any other university or other institute of learning.
