Everyday streets are both the most used and the most undervalued of cities’ public spaces. They constitute the inclusive backbone of urban life – the chief civic amenity – though they are challenged by optimisation processes. Everyday streets are as profuse, rich and complex as the people who use them; they are places of social aggregation, bringing together those belonging to different classes, genders, ages, ethnicities and nationalities. They comprise not just the familiar outdoor spaces that we use to move and interact and the facades that are commonly viewed as their primary component but also urban blocks, interiors, depths...@en

Streets are where the needs and values of different users and activities come together. Main streets in the Netherlands were either planned in major urban expansions or developed over time in the shape of ribbons upon dykes—‘long lines’ of continuously active streets. This chapter presents two cases from the Amsterdam metropolitan region: vanWoustraat-Rijnstraat, a main street planned as part of an urban expansion, and Westzijde, a main street that developed over time as part of a long line. While vanWoustraat-Rijnstraat is tightly organised and coherent in both appearance and function, Westzijde is characterised by a multitude of different buildings and functions. This study visualises the spatial-structural qualities that facilitate the evolving economic activities of these two streets. It explores the variation between them by morphological differentiation and determines several spatial characteristics that enable the mix: modularity of the urban plan, complementary ‘front’ and ‘back’ sides, structural coherence and territorial steps between the ‘front’ and ‘back’ sides to buildings, blocks and neighbourhoods.@en

Everyday streets facilitate various activities and movements, both indoors and outdoors. The second section of this book addresses the following question: What is the relationship between the urban form of everyday streets and the activities that occur on them? @en

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.@en

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.

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.@en

Since the 1970s, cities world-wide have been witness to radical de-industrialisation. Manufacturing was considered incompatible with urban life and was actively pushed out. As economies have grown, public officials and developers have instinctively shifted their priorities to short-term, high-yielding land uses such as offices, retail space and housing. Inner-city growth from New York to London and even Seoul have generally come at the expense of land uses such as manufacturing or logistics. Despite the odds, manufacturing is not in terminal decay in western cities. On the contrary, it is at the opening of a new chapter. Urban manufacturing can help cities to be more innovative, circular, inclusive and resilient. Recently, with increasing interest in the circular economy, with cleaner and more compact technology, with more progressive building codes for mixed use, with increasing awareness of the impacts of social inequality and with a clearer understanding of the value chains between the trade of material and immaterial goods, cities across the world are realising that manufacturing has an important place in the 21st century urban economy. While both enthusiasm for making is increasing and the value of manufacturing is becoming increasingly evident in cities, the topic remains extremely complex and challenging to manage. 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.@en

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

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, a link between quantitative analysis and theory is established, by testing two well-known theoretical propositions in urban morphology: the concept of the burgage cycle and the theory of natural movement.@en

Met het promotie-onderzoek van Birgit Hausleitner keren we terug naar de stedelijke context en in het bijzonder naar de randvoor waarden voor gemengde stedelijkheid. Zij laat zien waar kansen liggen voor functiemenging, ook op plekken waar je die niet verwacht. Birgit Hausleitner’s doctoral research brings us back to the urban context and in particular to the preconditions for mixed urbanity. She shows us opportunities for function mixing, some in unexpected places. @en

The Cities of Making 'Cities Report', offers an insight into urban manufacturing in three global cities - Brussels, London and Rotterdam. Each city has had a distinctive industrial heritage and is interpreting the future of manufacturing in very different ways. This report exposes unique qualities of each and common trends that may be relevant to many other European cities who are grappling with the future place of making. This chapter looks at the region comprising Rotterdam and The Hague, a richly productive landscape characterised by a vast port, intensive greenhouse based agriculture and urban areas. The recent economic and urban development of this region has resulted in a spatial configuration with unique characteristics, strongly interwoven with each other. Firstly, demand for space has led to the transformation of the region, which has been sculpted, made fit for specific purpose, with barely inches of unproductive land. Secondly, modernist principles introduced new functional zones with segregated areas specialising in mechanical manufacturing, chemical processing, logistics, to housing and leisure, resulting in a particular composition of building and urban areas. Thirdly, as a consequence of ongoing planning and adaptation of this productive environment, socio-economic stratification with a strong spatial manifestation continues to be noticed to this day. The region hosts a vast range of manufacturing. Many of these have emerged from the port and access to goods, resources and an international market such as chemical processing and machine production. Newer forms of manufacturing are spinning out of centres of innovation such as bio-technology and sensors and are showing that the city’s productive base is moving further and further away from the port. As the port itself changes and becomes increasingly automated, it leaves behind vast areas of land. While projected housing demand is putting pressure on the available vacant port areas, there are movements towards districts with new forms of production. Challenged by climate change and international competition, ambitions have been set for a radical transition towards a new economic models such as the Next Economy. The stakes are high for both private and public actors to focus on building out clean energy, resilient high-tech solutions, and radical innovation. However a range of visions and the strategic sectors have resulted in confusion about what should be stimulated and what the city’s new economic profile, regardless of what actually lands on the ground. In the absence of clarity and a holistic approach, the pressure mounts. Providing the desirable Next Economy workforce – those with higher incomes, education, and demands – with suitable housing and attractive urban environments puts in question the region’s economic, social and environmental stability.@en

Cities of making assesses the role and current state of manufacturing in three of Europe’s urban centres. Compiled by a consortium of partners in London, Brussels and Rotterdam it forms part of Cities of Making, a thirty-month programme exploring the future of urban based manufacturing in European cities. This report brings together insights about the current state of manufacturing in three European cities – Brussels, London and Rotterdam, each with a distinct industrial heritage. It aims to take a fresh and pragmatic look at the sector and in doing so highlight the challenges and opportunities faced in each of the cities, as well identifying potential for shared learning across the three.It identifies three key areas affecting the sector which warrant further investigation: governance and network models for supporting the sector; opportunities for harnessing resources and technology to develop more sustainable production; and spatial typologies for supporting modern urban manufacturing.@en

It has been argued that different urban configurations-planned vs. organic, treelike vs. grid like-perform differently when it comes to the intensity and distribution of pedestrian flows, built density and land uses. However, definitions of urban configurations are often rather abstract, ill-defined and at worse end in fixed stereotypes hiding underlying spatial complexity. Recent publications define morphological typologies based on quantitative variables (e.g. Barthelemy, 2015; Serra, 2013a; Gil et al., 2012; Berghauser Pont and Haupt, 2010) and solve some of these shortcomings. These approaches contribute to the discussion of types in two ways: firstly, they allow for the definition of types based on multiple variables in a precise and repeattable manner, enabling the study of large samples and the comparison between both cities and regions; secondly, they frame design choices in terms of types without being fixed and so open up for design explorations where the relation between the variables can be challenged to propose new types. This paper explores the typologies defined by Serra (2013a) and Berghauser Pont and Haupt (2010) further, as these target two of the most important morphological entities of urban form, namely the street network and the building structure. The purpose is to gain a better understanding of how types are composed and distributed within and across different cities. The method is based on GIS and statistical modeling of four cities to allow for a comparative analysis of four cities: Amsterdam, London, Stockholm and Gothenburg. For the street network, we process the Road-Centre-line maps to obtain a clean network model, then run segment angular analysis to calculate the space syntax measures of betweenness at different metric radii, defining the "centrality palimpsest" (Serra, 2013a). For the building structure, we process elevation data to obtain building height, then run accessible density analysis for all building density metrics (FSI, GSI, OSR, L) using the Place Syntax Tool (Berghauser Pont and Marcus, 2014). The street and building types are defined using cluster analysis (unsupervised classification), following a similar approach to Serra (2013a). The result is a typology of street ('paths') and building types ('places'), with different profiles of centrality and density across scales. The spatial distribution and frequency of these types across the four cities gives an objective summary of their spatial structure, identifying common as well as unique traits.

In cities manifold actors are continuously taking decisions and proposing interventions, which are driven by, but also change, spatial conditions and their performance on a variety of scales. Understanding how this interplay works is crucial for urban designers and planners. However, this complexity asks for new methods of analysis or combinations of existing methods that better inform urban designers which is exactly what this paper is aiming at. The use of typologies to describe a complex reality has been both attractive to practice and an important research branch within urban morphology. This paper presents a configurational typology that is not simply representing the physical environment, but rather its affordances (Gibson,1979) where we use as example the conditions needed for various kinds of micro-businesses. It combines properties that describe the position of a specific urban block within the street network of a city, characteristics of the direct surrounding of a block as well as characteristics describing the plot configuration within a block. The spatial characteristics most often associated with the spatial organisation of activities were selected from literature. The statistical method of two-step-clustering was used to distinguish clusters and thereby the different types of configurations. The clustering was tested in an explorative process to understand which characteristics were relevant to distinguish the main urban configurations of the urban system. The results are presented for the city of Amsterdam. The same method can be applied to other phenomena such as co-presence as well as other cities and thereby allows understanding the variety of such types, but also the existence of generic types. In a next step this typology could be tested for applicability in practise.
