The Rise of the ‘Invisible Detail’: Ubiquitous Computing and the ‘Minimum Meaningful’

The architectural detail has provided the essential material building block for conveying an idea. Carlo Ratti and Matthew Claudel of the SENSEable City Lab at the Massachusetts Institute of Technology (MIT) ask how this, though, is all set to change in a digital context. As technologies shrink and vanish from sight, what might become the new minimum meaningful unit for architecture? How might a new relational scale establish itself, at the level of the ‘invisible detail’ or the microchip? How might this, in turn, change the very nature of buildings as they become highly responsive, human-occupied transmitters?     

The Villages,Florida: Small-town Metropolitanism and the ‘Middle of Nowhere’

With over 110,000 inhabitants , The Villages is the world's largest retirement community. Its numerous distinct ‘villages’, surrounded by artificial landscaping and golf courses and served by three ‘downtowns’, cater to those who crave the idealised rural life of times gone by while also offering the convenience and stimulation of the modern metropolis. Deane Simpson , leader of the Master's programme in Urbanism and Societal Change at the Royal Danish Academy of Fine Arts School of Architecture, investigates.     

A computational approach to ‘The Image of the City’

In The Image of the City Lynch describes how individuals perceive and recall features in urban spaces. The most distinctive elements in the urban landscape - categorised in paths, nodes, edges, districts and landmarks - give shape to individuals' mental representation of the city. Lynch’s approach has stimulated research into spatial cognition, urban design and artificial intelligence, and it still represents an essential pillar in the analysis of urban dynamics. Nevertheless, an explicit link between The Image of the City and GIScience has not been completely explored yet. In this paper, a computational approach to The Image of the City is proposed. Different perspectives in spatial cognition and GIS research are integrated to obtain a complete Image of the City, in which the most salient elements are shared by a large part of citizens. Nodes, paths and districts were identified through network science techniques. Methods drawn from the information approach to The Image of the City are used to detect landmarks, integrating the complexity of points of reference in their visual, structural and semantic components, as conceptualised by Lynch and successive research. The methods were applied to the central area of Boston and built using freely available spatial datasets. Results were compared to Lynch’s maps to evaluate the methodology: besides a considerable discrepancy with regard to landmarks, a good correspondence for paths, nodes, edges and districts was found.     

‘The spring of hope,the winter of despair’: an unfinished narrative of Mediterranean cities

Early in 2011, a powerful surge of protest calling for political and social change swept along the North African shoreline. Not for the first time, and almost certainly not for the last, the established rhythms of urban life in the region were to be severely disrupted. The patient work of well-laid plans counted for little as people took to the streets and military governments resisted; overnight, public squares became places of protest and even battlegrounds. Tunis, Tripoli and Alexandria – the three cities that feature in this paper – were by no means the only places to feel the strong winds of change. Moreover, all three of the case studies have long histories and, as with so many other cities around the Mediterranean, turbulence is nothing new. It is hard to think of other parts of the world where cities have so often experienced changing fortunes: at one moment in history nourishing the growth of civilization, at another trapped in a spiral of decline. Located between three continents, in a region of geological as well as geopolitical instability, Mediterranean cities are familiar with bad times as well as good. This paper explores the nature of this volatile process and its impact on urban life and form.     

The ‘Place’ of Cosmopolitan Architecture

The paper takes as its point of departure the necessity to open a space between the international and the national. That space will be as much political as will be one that allows for a certain architecture. For the sake of argumentation that space has been identified as the cosmopolitan. What characterises the cosmopolitan is the possibility that it is the form of modernity once the modem has been freed from the oscillation between the national and the international. Once modernity is introduced then the question to be addressed is not what is modern architecture but what is the architecture of modernity. Part of the argument developed here is that a beginning can be made once it is understood that modernity has to eschew the symbol. And yet, the symbols that proliferate are either national or international. Consequently, this gives rise to a complex interplay between the cosmopolitan, modernity and the possibility of an architecture that is non-symbolic. The question of how to think this complex set of relations is the project undertaken by the paper.     

‘The party’s over’: critical junctures,crises and the politics of housing policy

The key argument set out in this article is that historical and comparative forms of investigation are necessary if we are to better understand the ambitions and scope of contemporary housing interventions. To demonstrate the veracity of our claim, we have set out an analysis of the UK housing polices enacted in the mid-1970s as a basis for comparison with those pursued 40 years later. The article begins with a critical summary of some of the methodological approaches adopted by researchers used to interpret housing policy. In the main section, we present our critical analysis of housing policy reforms (implemented by the Labour government between 1974 and 1979) noting both their achievements and limitations. In the concluding section, we use our interpretation of this period as a basis to judge contemporary housing policy and reflect on the methodological issues that arise from our analysis.     

Virtual enclosure,ecosystem services,landscape’s character and the ‘rewilding’ of the commons: the ‘Lake District’ case

Abstract

It is paradoxical that, while there is a generally increasing recognition of the scientific and cultural importance of conserving ‘semi-natural’ pastoral environments, and the negative effects of their widespread abandonment and overgrowth, British ‘rewilding’ activists and environmental managers are effectively advocating policies that will have a similar negative effect on the character of the semi-natural pastoral commons of places like England’s iconic Lake District. This situation, it will be argued, owes to the mindset of ‘virtual enclosure’ whereby the character of landscape is pre-defined by an assumed, behind-the-scenes, Euclidean/Ptolemaic spatial logic that leads to the comprehension of nature as a bounded scenic property; an (e)state of nature with its own economic system and services. This mindset is antithetical to both the practice of pastoral commoning and much contemporary natural science and conservation policy. It fits well, however, with older teleological ideas of nature, as well as modern ideas of privatisation, private property and management control.     

The difference of ‘being diverse’: City branding and multiculturalism in the ‘Leicester Model’

This city profile on Leicester focuses on the representation of ethnical diversity in city branding. Through a historical approach, the paper discusses how the local authorities have taken advantage of the arrival of different migration flows into the city, in order to redefine its post-industrial identity in terms of multiculturalism, tolerance and inclusivity. In so doing, the paper emphasises the combination of deliberate marketing communicative activities, the provision of services for attracting and retaining foreign businesses and the creation of an open urban milieu where various ethnic groups are free to express and celebrate their own cultures through festivals and events. The paper identifies the alignment between place communication and place ‘offerings’ development as the crucial element underpinning Leicester's model for multicultural cooperation and critically assesses the recent challenges that are being posed to the sustainment of a multicultural city image.     

Conceptualizing ‘the Urban’ Through the Lens of Durban,South Africa

Contemporary urban theory raises many questions about how ‘the urban’ is being conceptualized in a fast changing world that is approaching an urban epoch. Evolving debates about what it means to be urban, including the similarities and differences between so-called northern and southern cities, the future of cities, the way to manage and sustain cities, and cities’ relationships to the new Urban Agenda and the Sustainable Development Goals, reveal the need for urban theory that can explain and provide insights into contemporary urban governance, processes, and outcomes. This special issue uses Durban as a lens to provide insight into the changing nature of cities in the Global South and Africa in particular, which encapsulate and reflect both formality and informality; tradition and modernity; uneven and unequal growth and social transformation; environmental crises and ‘resilience and sustainability’. This paper reflects on the dominant processes shaping the development of the city, revealing the challenges, tensions, and opportunities that emerge as the city assembles new ways of being urban, through the rationalities, knowledge, experiences, practices and actions of the state, citizens, and the private sector.     

The ‘valley of ashes’ and the ‘fresh green breast’: metaphors from The Great Gatsby in planning New York

ABSTRACT

Visions in planning of what a city could or should be tend to be constructed around metaphors, rhetorical tropes that crystalize the image of a preferable future city. Such metaphorizations are never innocent: they draw on pre-existing cultural narratives and activate particular frames of expectation. This article examines two metaphors used in the planning of New York City, and its shores, in particular: the spectre of the ‘valley of ashes’ and the dream of the ‘fresh green breast’. These metaphors, taken from F. Scott Fizgerald’s novel The Great Gatsby (1925), appear time and again in the planning and thinking of the New York shoreline, from Robert Moses’s plans for Flushing Meadow to Major Bloomberg’s waterfront development and Eric Sanderson’s vision of a 2406 New York in Mannahatta (2006). This article examines how the metaphors of the ‘valley of ashes’ and the ‘fresh green breast’ have been adapted throughout decades of planning New York City to accommodate changing relationships, conflicts and ideals, always infused by a pastoral undercurrent that is already questioned in Fitzgerald’s novel.     

South African ‘know-how’ and Israeli ‘facts of life’: the planning of Afridar,Ashkelon, 1949–1956

In 1949, in the newly founded state of Israel, South African architects Norman Hanson and Roy Kantorowich planned the city of Ashkelon and, within it, the exclusive neighbourhood unit Afridar. Managed by the South African Jewish Appeal, which initiated and funded the project, Afridar presented a radical exception to Israel’s centralized planning approach during that period. An early example of a semi-private settlement initiative for an ethnic and class-based enclave reserved for ‘Anglo-Saxon’ Jewish immigrants, it functioned as a ‘model town’ for the immigrant population from the Middle East and North Africa, which was housed by the government in the rest of the city of Ashkelon. Afridar’s enclave reproduced planning practices from South Africa, which had been coloured by race since the 1920s. Despite its exclusive image, it was modelled after progressive experiments in the design of Native Townships. Their main objective of such experiments was to improve the standards of housing of racially discriminated populations yet, in practice, they served as a tool to implement apartheid policies. This paper interrogates this ambivalence of social aspirations and complicity with state segregation practices through examining the translation of apartheid’s planning practices to the Israeli context, and the negotiations and conflicts this translation entailed.     

The ‘People’s City’

The mid-20th-century communist ideal was for cities that were ‘of the people, by the people and for the people’. Wang Jun , an editor at Outlook Weekly magazine and author of a best-selling book on the planning of Beijing, describes how the ambition to accommodate public life in urban space is a relatively modern phenomenon that goes against the grain of a long tradition of landownership in China. Given this background, can the original notion of the ‘People's City’ ultimately survive the current wave of property privatisation? Copyright © 2008 John Wiley & Sons, Ltd.     

‘Clubification’ of urban public spaces? The withdrawal or the re-definition of the role of local government in the management of public spaces

This paper reports on a case study on the forms of urban public spaces governance that are emerging in the UK out of a rearrangement of governance responsibilities between local government, communities and private interests. Based on cases of public spaces in London under a variety of different governance arrangements, the paper critiques the dominant explanations of those processes, and suggests a far more complex picture in which empowerment and disempowerment of stakeholders of various types happen at the same time, along complex lines defined by geography, strength of stake and representation of that stake in a formalized governance transfer contract. As the paper suggests, the resulting ‘localization’ of governance, the devolution of governance responsibilities to those local actors with the stronger stake in them, does not intrinsically reduce the publicness dimension of public space, but it reshapes that notion towards one with a variety of ‘publicnesses’, with their own governance dynamics and positive and negative consequences.     

‘The beautiful and useful laws of God’: Burnham's Swedenborgianism and the Plan of Chicago

The phrase ‘beautiful and useful laws of God’ comes from a letter the young Daniel H. Burnham wrote to his mother. Knowledge of Burnham's religious beliefs is profoundly important for a deeper, more nuanced understanding of his intentions and motivations for the 1909 Plan of Chicago. This influence is underestimated, in part, because it has no overt, dramatic representation in the plan and is overshadowed by the apparently contradictory but captivating rendered perspectives.     

A practitioner's view of the ‘Regenerative Paradigm’

The Building Research & Information special issue titled ‘Regenerative Design and Development’ (2012, volume 40, number 1) describes emerging theory and practices. This commentary reflects on some practical aspects of understanding and implementing regenerative development. Design professionals can certainly engage with the concepts of regenerative design to increase social and natural capital. Its scope provides for increased boundaries of practice by considering not only the building as an artefact, but also the potential to broaden the brief and engage with wider issues: the surrounding site, the encouragement of a low-carbon lifestyle and providing a positive contribution to eco-services. Drawing on some experience from practice, key challenges are raised: What impediments are likely to arise? What methodologies are needed for overcoming impediments and integrating these ideas into practice? How can the regenerative concept be applied to an urban context? Concern is expressed about how the complexity of systems thinking can be translated into the decision-making processes without adding undue complication. An important implication of regenerative development is for the existing building stock to be treated as a valuable resource of embodied carbon; its prolonged life and avoided demolition are fundamental.

Le numéro spécial de Building Research & Information intitulé « Conception et Développement Régénérateurs » (2012, volume 40, numéro 1) décrit la théorie et les pratiques émergentes. Le présent commentaire réfléchit à certains aspects pratiques de la compréhension et de la mise en oeuvre du développement régénérateur. Les professionnels de la conception peuvent certainement adopter les concepts de la conception régénératrice afin d'accroître le capital social et naturel. Son champ d'application permet d'élargir les limites de la pratique en envisageant non seulement le bâtiment comme un artefact, mais également les possibilités d'extension du cahier des charges et de prise en compte de problèmes plus larges: le site environnant, l'encouragement d'un style de vie bas carbone et la fourniture d'une contribution positive aux éco-services. En s'appuyant sur une certaine expérience issue de la pratique, les défis majeurs sont soulevés: quels obstacles sont susceptibles d'apparaître? Quelles méthodologies sont nécessaires pour surmonter ces obstacles et intégrer ces idées dans la pratique? Comment le concept régénérateur peut-il être appliqué à un contexte urbain? Des inquiétudes sont exprimées quant à la manière dont la complexité de la pensée systémique peut trouver sa traduction dans les processus de prise de décision sans ajouter d'excessives complications. Une implication importante du développement régénérateur est que le parc bâti existant doit être traité comme une ressource précieuse de carbone intrinsèque; il est essentiel d'en prolonger la durée de vie et d'en éviter la démolition.

Digital Solipsisim and the Paradox of the Great ‘Forgetting’

Neil Spiller counters the main theme of this issue by questioning the dominant focus on production and new technologies in architectural culture, which places a premium on the generation of ‘ever more gratuitous complex surfaces and structures’. Could this inward-looking emphasis on process and obsessive love of new technologies be at the expense of the final product? Are we in danger of producing artefacts that lose sight of human expression and poetics in the competitive drive for greater complexity? Are we, in fact, heading towards a great ‘forgetting’ in which humanity is subtracted from the architectural product?     

‘Orthodox’ and ‘alternative’ explanations for the reduction of urban violence in Medellín,Colombia

In 2016, 43 of the 50 most dangerous cities in the world were located in Latin America. In reducing levels of urban violence and preventing future outbreaks, approaches developed in Western Europe and North America are the most influential and have been subjected to considerable testing in high-income urban environments.

This article focuses on Medellín, Colombia. By drawing from qualitative data collected in Medellín, the article scrutinises claims that the social urbanism policies caused the significant reduction in homicides. An alternative explanation for the reduction in homicides is then presented, focusing on the methods of the perpetrators of violence.     

‘London particular’: the city,its atmosphere and the visibility of its objects

Over the course of the nineteenth century, the smoke-filled atmospheres of London and other industrial cities were the subject of aesthetic, scientific and legal inquiry. Reconstructing the conjunction of such inquiries in a pivotal architectural episode—the rebuilding of the Houses of Parliament—reveals an important transformation in the understanding of the relationship between a city and its architectural objects. Where it once seemed possible to regard these objects (and their architects) as independent, discrete participants in the larger material and administrative domains of the city, the expanding knowledge and judgements of the atmosphere and its effects produced an entirely different perception. The city and its architectural objects were co-extensive, involuntary participants in an encompassing process of change registered by two newly recognised categories: decay and maintenance.     

Bugs,Bats and Animal Estates: The Architectural Territories of ‘Wild Beasts’

For architecture, animals and insects have conventionally represented the threat of infestation - a parasitic and insanitary uninvited presence. Could the animal world, however, offer previously untapped opportunities for design innovation? At a time when the relationship between architecture and nature is coming under question, Ben Campkin takes the opportunity to bring attention to the wider social and geographical processes lying beneath the occupation of the man-made environment by insect and animal life.
