Typologies have always played an important role in urban planning and design practice and formal studies have been central to the field of urban morphology. These studies have predominantly been of a historical-qualitative nature and do not support quantitative comparisons between urban areas and between different cities, nor offer the precise and comprehensive descriptions needed by those engaged in urban planning and design practice. To describe contemporary urban forms, which are more diffuse and often elude previous historic typologies, systematic quantitative methods can be useful but, until recently, these have played a limited role in typo-morphological studies. This paper contributes to recent developments in this field by integrating multi-variable geometric descriptions with inter-scalar relational descriptions of urban form. It presents typologies for three key elements of urban form (streets, plots and buildings) in five European cities, produced using statistical clustering methods. In a first instance, the resulting typologies contribute to a better understanding of the characteristics of streets, plots and buildings. In particular, the results offer insight into patterns between the types (i.e., which types are found in combination and which not) and provide a new large scale comparative analysis across five European cities. To conclude, we establish a link between quantitative analysis and theory, by testing two well-known theoretical propositions in urban morphology: the concept of the burgage cycle and the theory of natural movement.

A large proportion of European inhabitants live in dispersed urban settlements, much of which is labelled as sprawl, defined by monofunctional, low-density areas. However, there is increasing evidence that this may be an overly simplistic way of describing territories-in-between (TiB). This paper defines and maps functional mix in six dispersed urban areas across Europe, applying a method that goes beyond existing land-use-based mixed-use indicators but considers functional mixing on the parcel level. The paper uses data on the location of economic activities and the residential population. It concludes that, in eight cases from four European countries, mixed-use is widespread and that more than 65% of inhabited areas are mixed. Moreover, the paper relates functional mixing to specific settlement characteristics: permeability, grain size, centrality and accessibility, and connectivity. This demonstrates that functional mixing is not the result of local urban morphology or planning instruments, but of the multi-scalar qualities of a location. Therefore, there is a requirement to coordinate planning and design through different scales if mixed-use areas are to be seen as one strategy for achieving greater sustainability in the spatial development of dispersed areas.

This article describes the TU Delft's 2020 experiences during the pandemic in teaching and learning urban design and planning for (post-)Covid-19 times. The article presents the view why, that and how the themes of spatial resilience and governance resilience should be emphasized in urbanism curriculums. Additionally, it discusses the value of creating well-organized and empathetic online design studios as an inspiring learning environment for both student and teacher.

<p>Planning practice in the Global South often defines a border between formal and informal developments ignoring the complex and nuanced reality of urban practices and, consequently, worsening segregation. This article proposes an alternative view of socio-spatial segregation that shifts the distinction between formal/informal towards one that emphasises access to opportunities and their relationship with the spatial structure of the city. Under this alternative framework, applied to the case of the Valle Amauta neighbourhood in Lima, Peru, we reflect on how socio-economic activities, shaped by spatial conditions and social practices, increase or reduce socio-spatial segregation. Our findings suggest that a shift towards strategies aimed at increasing accessibility to centrality, provided by the density of social and economic activities, could offer new opportunities for planning practice and theory in the Global South.</p>

Urban manufacturing and manufacturers play a vital role in delivering circular economy ambitions through processing materials, providing skills and technology for repair or reconditioning goods and the capacity to deliver innovative technology. The transdisciplinary approach of Cities of Making (CoM) puts forward three ways of addressing manufacturing, and by extension, circularity, within urban areas. Central to triangulate the facilitation of urban manufacturing are the perspectives of (1) material flows and technology, (2) spatial design (3) people and networks. The integration of the three pathways requires convergence while retaining the richness of the three perspectives. The challenge is to find a common language that provides a comparable, operative framework for exploring possible solutions. The CoM framework of integration followed three main principles: (1) reducing the complexity of information, (2) reducing the complexity of combinations of possible solutions, and (3), applying an accessible, applicable instrument for the solutions. The resulting pattern language is co-created in a transdisciplinary setting and is also an instrument for the transdisciplinary application. The low threshold accessible system of solutions allows actors from different disciplines to access patterns developed in the context of another discipline and laypeople who are affected or interested to co-create.

This book attempts to shed light on the ways manufacturing can address urban challenges, it exposes constraints for the manufacturing sector and provides fifty patterns for working with urban manufacturing. This book has been written as a manual to help politicians, public authorities, planners, designers and community organisations to be able to plan, discuss and collaborate by developing more productive urban manufacturing. The book is split into two parts. We first cover an abridged history of the late nineteenth and early twentieth centuries, noting how European cities evolved rapidly by harnessing manufacturing, and then how the late twentieth century led to a radical shift in how cities work and think. We’re now at a crossroads between actors that do not see the need for manufacturing in cities and those that consider it vital for a prosperous urban future. Part of the tension comes from the fact that manufacturing is considered a ‘weak land use’ compared to activities such as real-estate development, which has been considered more financially attractive by many actors in the private and public sector. This real estate-oriented development narrative is increasingly regarded as short-sighted, but will not change without an alternative vision. We have therefore elaborated a narrative on how urban manufacturing responds to four specific challenges facing cities and how in turn manufacturing needs cities. In practice, planning and design for a topic like this is highly challenging. The second part of the book is intended as a handbook. By synthesising our research and fieldwork conducted in a number of cities, we have encountered many similarities in terms of problems, challenges and solutions for urban manufacturing. Inspired by the seminal 1977 book, ‘A Pattern Language’ we have translated our findings into fifty patterns which help render the diversity of issues concerning manufacturing more tangible. As both teamwork and negotiation are necessary, exercises and methods are provided to use the patterns. Finally, we have set out twelve key action areas as possible starting points for supporting urban manufacturing.
