The interplay between the form and infrastructure of modern cities produces spatial and temporal dimensions which allow for erratic growth and fragmentary perception. Though their origins can be clearly seen in urban development since the Renaissance, density, movement, and pace in contemporary cities increase as meaningful boundaries are erased by rising consumption of services and a spate of traffic (automobile, communication, utility). While property values limit accessibility to inner urban space, the city expands outwardly, generally following the path of least resistance. In so doing, the increased demands on infrastructure cleave existing urban textures, creating anomalies in the landscape. As a result, large open spaces for public use are either dislocated (to suburbia), restricted (institutionalized where most public), or simply "left over" as remnants of previous programs (abandoned buildings) or the fall-out of large scale construction (highways, public transport, utilities, etc.). The potential of these latter spaces for public use is often unrecognized. This thesis will argue that due to their very natur~, cities produce such spaces by default and that they can be employed for public use as a frontier in the urban psyche. The design for such a frontier would support a variety of programs based on public events. As soon as one event takes place, another would follow according to the rhythm of the city. In this way, it could act as a stabilizer by activating places which are really just dormant and providing a permanent fixture for civic activity.

Why have so many central and inner cities in Europe, North America and Australia been so radically revamped in the last three decades, converting urban decay into new chic? Will the process continue in the twenty-first century or has it ended? What does this mean for the people who live there? Can they do anything about it? This book challenges conventional wisdom, which holds gentrification to be the simple outcome of new middle-class tastes and a demand for urban living. It reveals gentrification as part of a much larger shift in the political economy and culture of the late twentieth century. Documenting in gritty detail the conflicts that gentrification brings to the new urban 'frontiers', the author explores the interconnections of urban policy, patterns of investment, eviction, and homelessness. The failure of liberal urban policy and the end of the 1980s financial boom have made the end-of-the-century city a darker and more dangerous place. Public policy and the private market are conspiring against minorities, working people, the poor, and the homeless as never before. In the emerging revanchist city, gentrification has become part of this policy of revenge.

In a globalizing world, frontiers may be in flux but they remain as significant as ever. New borders are established even as old borders are erased. Beyond lines on maps, however, borders are spatial zones in which distinctive architectural, graphic, and other design elements are deployed to signal the nature of the space and to guide, if not actually control, behaviour and social relations within it. This volume unpacks how manipulations of space and design in frontier zones, historically as well as today, set the stage for specific kinds of interactions and convey meanings about these sites and the experiences they embody. Frontier zones organize an array of functions to facilitate the passage of goods, information, and people, and to define and control access. Bringing together studies from Asia, Africa, the Middle East, Europe, and North America, this collection of essays casts a wide net to consider borders of diverse sorts. Investigations of contemporary political frontiers are set within the context of examinations of historical borders, borders that have existed within cities, and virtual borders. This range allows for reflection on shifts in how frontier zones are articulated and the impermanence of border emplacements, as well as on likely scenarios for future frontiers. This text is unique in bringing together a number of scholarly perspectives in the arts and humanities to examine how spatial and architectural design decisions convey meaning, shape or abet specific social practices, and stage memories of frontier zones that no longer function as such. It joins and expands discussions in social science disciplines, in which considerations of border practices tend to overlook the role of built form and material culture more broadly in representing social practices and meanings.

This book offers the first full-length comparative analysis of urban development trajectories in Eastern Africa and the political dynamics that underpin them. It offers a multi-scalar, historically-grounded, and interdisciplinary analysis of the urban transformations unfolding in the world's most dynamic crucible of urban change.

In Design Outlaws, Christopher Zelov, Phil Cousineau and Brian Danitz have gathered together the interviews of over twenty of the leading designers and architects from their award winning documentary film: Ecological Design: Inventing the Future. This far reaching collection is lavishly illustrated and will inspire both the professional and the general reader alike.

New ideas and technologies are transforming the ways we build and inhabit underground space. This book explores how these innovations can help to make our increasingly dense, climate-stressed cities both more resilient and more of a pleasure to live in. While it sets out practical design approaches, Underground Cities is not a technical manual. Designed for everyone with an interest in the future of our cities, it is beautifully illustrated and written in an accessible style that draws on the rich tradition of underworlds, both real and imagined, in art, history and poetry. Global in scope, the book ranges across continents as it surveys the vast expansion in the potential of the underground. The opening section, 'A New Frontier', looks at two pioneering cold-climate cities, Montreal and Helsinki, which developed new uses for the underground from the 1960s on. The closing section, 'Looking Forward', offers glimpses of the city of the future - of what we might be able to achieve in the next 50 or 60 years. Focusing on Hong Kong, Singapore and Tokyo, it shows projects that are going deeper, achieving a greater synergy of uses and preparing the way for new urban forms. In between, it reviews a range of innovative ideas and presents buildings and projects by leading international architects and artists, among them Jun'ya Ishigami, James Turrell, Dominique Perrault and Thomas Heatherwick, which highlight the advances in technology that are making it possible to bring the elements of nature - light, air, vegetation - deep underground. Works include a subterranean oasis, a refuge from the desert heat; a museum extension that deploys light and colour to define space; a multi-modal underground transport hub that evokes the arcades of nineteenth-century Paris, but with an added profusion of plants; and a troglodytic house and restaurant, sunk into the earth to create atmosphere.
