'Pattern language' is about ‘rule-based’ process innovation that can be used for project management and reporting methods. Alexander explicitly stressed the important of procedural aspects of sustainability and recording / reporting the process and being clear about your ‘working out’. Indeed some urban designers suggest that using a 'pattern language' is necessary to support multidisciplinary and complex urban development projects[4]. Following this ‘pattern language’ leads to the need for an agreed collaborative process that can be accepted and understood by the scope of stakeholders. So the approach has given rise to certain levels of criticism that it is a deterministic approach[5] and too rational for a creative discipline[6]. Yet at the heart of any critique is still the need for an agreed collaborative process, grounded in structuralism or ‘rule-based’ design theory[7], versus an individualistic and elitist ‘black box’ design process.
Beyond these criticisms of Alexander promoting a deterministic process, or a vernacular or time-based style[8] (in seeming rejection of the international / modernist style) it can be understood as an early comprehensive and integrated process of design that explicitly and actively involves occupants / participants. This degree of active participation, explicit in his pattern language, has made him and his methodology of significant interest to political theorists[9]. Here there are transferable lessons in how active involvement in design stages leads to more active citizen involvement, civic engagement and local management. There is also a growing interest in his theory and projects arising from the emphasis of sustainable and participatory design processes[10].
His grounded theory has made him a reluctant cause-celebrity for the democratization of planning and development. His approach to sustainability is about reconstructing generative systems. Good design; indeed local character and appropriateness; emerges from the collective knowledge and decisions of multiple agents rather than top-down professional views being imposed. It is an example of the ‘wholeness’ principle in action that delivers functionality for the community in the short-term and empowerment over the medium to long-term. This process has a growing influence over patterns and problem solving in programming[11]. Indeed emergent patterns, described as a sequence of tasks in an appropriate format with a strong graphic bias, also have applications for technical communication and computing, with commentators arguing[12] that Alexander’s 'pattern language' is in effect a type of algorithm that can be used to structure and organize the connections between technical communications.
His ‘process-orientated urban design’ lessons continue to be applied in projects through the developed and developing worlds[13] from housing layouts to the neighbourhood design scale[14]. The methodology of ‘pattern language’ and the idea of ‘design sequencing’ is also changing approaches to environmental education. There are a growing number of educationalists teaching the process of design[15]; as much as the theoretical underpinning; as a process suitable for ‘non- experts’ that is also a replicable process[16], that is in effect a description of what goes on inside a designer’s’ head and their thought process. They are beginning to ask the same sort of questions we are attempting to address in this project, namely ... What are the critical principles of codesign or generative design? ... How can we apply and improve on these by learning through the process in this context?[17] Simply by attempting to articulate, capture and link the steps undertaken in the design process we should begin to see some of these patterns.
Nowhere are the impacts of Alexander's ‘pattern language’ more evident than in the approach taken to his entry for the Previ international housing design competition in Lima, Peru. Some early reflections of his involvement in the project and the competition process have been published[18], but out intention is to re-investigate this project and Alexander’s involvement forty years plus after the commencement of the scheme.
