Informing an urban design process by way of a practical example

Urban design and sustainability are critical issues in creating better urban environments. The UK government is endorsing sustainability through its sustainable communities agenda and is urging the public, private and third sectors to emphasise high quality design in their urban development projects. However, with little guidance as to how to design sustainable urban development projects, decision-makers may end up wasting time, money and resources in projects that are unsustainable for themselves, the community and beyond. One option for decision-makers is loosely to follow a generic process for urban design that demonstrates, by way of a series of stages and activities, when to make decisions and to consider sustainability, what tools are needed to make decisions and who should be making decisions. To further the understanding of the use of a process in sustainable urban design decision-making, a baseline model was first created that amalgamates stages and activities from relevant processes found in a variety of disciplines and professions. A case study was then conducted, showing the process for the urban design and development of Brewhouse Yard, Clerkenwell, London. Through analysis of interviews, archival material and site analysis, three distinct periods of the process were discerned. These periods are discussed by way of process stages, decisions, tools and sustainability. The paper then compares this process with the baseline process to understand how the former can help improve the latter as a tool for assisting decision-makers in creating more sustainable urban environments.
