Due to the regulations on land ownership [1, 2].

However, in addressing the need for new workers and fresh graduates to live. The reason for their housing for low-income people, the social and cultural popularity is not only because of the affordable rents but aspects of urban villages should be duly considered. also because of their convenient locations in the city centre. This paper aims to identify and elucidate the It is also worth looking at the social and cultural aspects of salient features of urban villages based on case studies in urban villages.

IDENTIFICATION OF ESSENTIAL ELEMENTS AND ELUCIDATE SALIENT FEATURES OF URBAN VILLAGES C. Community Formation with Sense of Belonging In order to understand and learn from urban villages, Urban villages in China may be described as it is essential to identify their key elements in terms of informal settlements by some researchers [7], but social spatial flexibility, street-level interactions and community benefits that urban villages offer should not be ignored.

  • The Urban Village: a Real Or Imagined Contribution to Sustainable Development?
    The Urban Village: A Real or Imagined Contribution to Sustainable Development? Mike Biddulph, Bridget Franklin and Malcolm Tait Department of City and Regional Planning, Cardiff University July 2002 The research upon which this report is based was kindly funded by the Economic and Social Research Council (ESRC). 1 Background A number of development concepts have emerged which claim that, if achieved, they would deliver more sustainable urban environments. Specifically these concepts seek to transcend typical patterns of development, and instead capture and promote a different vision. Such concepts include the compact city (Jenks et al, 1996), the polycentric city (Frey, 1999), the urban quarter (Krier, 1998), the sustainable urban neighbourhood (Rudlin and Falk, 1999), the urban village (Aldous, 1997), the eco-village (Barton, 1999), and the millennium village (DETR, 2000). Gaining acceptance for these concepts and translating them into practice has, however, proved more difficult, and the only one which has resulted in any significant number of built examples is the urban village. Despite the proliferation of developments under the urban village rubric, little academic research has been conducted into the phenomenon. The main exception is the work of Thompson-Fawcett (1996, 1998a, 1998b, 2000), who has investigated the background and philosophy of both the urban village and of the similar New Urbanism or Traditional Neighbourhood Development (TND) movement in the US. Her empirical work in the UK is limited to two case studies, the location of one of which is also the subject of a less critical paper by McArthur (2000). Both Thompson-Fawcett and commentators on the TND argue that the thinking behind the respective concepts is utopian, nostalgic, and deterministic, as well as based on a flawed premise about contemporary constructions of community (Audirac and Shermyen, 1994, Thompson-Fawcett, 1996, Southworth, 1997).

  • Case Study: Advancing Social Equity in Arlington, Virginia
    Local Governments, Social Equity, and Sustainable Communities ADVANCING SOCIAL EQUITY GOALS TO ACHIEVE SUSTAINABILITY CASE STUDY SERIES ADVANCING SOCIAL EQUITY in Arlington, Virginia ABOUT THIS PROJECT: ADVANCING SOCIAL EQUITY GOALS TO ACHIEVE SUSTAINABILITY This research was conducted by ICMA and Arizona State University to identify and describe current activities, lead- ing practices, and achievements of sustainable communities created through a comprehensive, integrated approach supported by inclusive engagement. Based on results of the ICMA Sustainability Survey in 2010, a follow-up survey was sent to 300 local governments whose original responses showed high levels of sustainability activity. Using results from the follow-up survey and primary and secondary research on leading social sustainability practices around the United States, nine communities whose responses indicated high levels of social equity-related activity were selected for case studies. Case study communities include the following:* • Washtenaw County, MI (Pop. 344,791) • Lewiston, ME (Pop. 36,592) and Ann Arbor, MI (Pop. 113,934) • Durham, NC (Pop. 228,330) • Dubuque, IA (Pop. 57,637) • Arlington, VA (Pop. 207,627) • Hayward, CA (Pop. 144,186) • Clark County, WA (425,363) • Manatee County, FL (Pop. 322,833) • Fort Collins, CO (Pop. 143,986) Each case study details findings from individual communities that provide insight into how they have been able to promote social equity and achieve greater social sustainability through their policies, programs, and other activities.

RICHARD BRUCH 2013 resume Richard Bruch Landscape Architect Bachelor of Landscape Architecture, University of Melbourne. Bachelor of Commerce (Econometrics, Economics), Monash University. Document designed and produced by Richard Bruch, April 2013. PERSONAL STATEMENT My passion in work is partnering with communities and decision makers to develop creative, environmentally responsible & socially equitable cities and places. I am tertiary educated in both landscape architecture and economics, and have extensive experience working as a practitioner in community development and community engagement. Over four semesters from February 2009 until November 2010, whilst completing my studies in landscape architecture at University of Melbourne, I was employed as a subject designer, sessional tutor and guest lecturer in a range of subjects from across the Bachelor of Environments, Master of Landscape Architecture, Master of Architecture and Master of Community Cultural Development. At this time I also established Urban Village Melbourne - a network of young creatives who collaboratively produced participatory public art projects and events, and provided professional services in environmental design and community development to local government clients. Also during this period, I established an ongoing professional and mentoring relationship with Eureka Community Development Services. In late 2010, upon completion of my studies at University of Melbourne, I commenced work with Hansen Partnership as a Graduate Landscape Architect. During 2011, I was approached by a past client at the City of Melbourne, with the offer to undertake contract work as Community Engagement Coordinator for the Swanston Street Redevelopment, and later for the Queen Victoria Market Redevelopment.

This design proposal responds to a complex of problems in housing delivery in inner city areas, including the lack of family-friendly, af- fordable housing as well as more typically conceived ‘social housing’, catering to the needs of disabled, disadvantaged or at-risk popula- tions. The key ideas driving the master planning of this site are: - affordable, adaptable, high quality housing - place to play, and commune, for all ages and abilities - eco-responsive, passivehaus design. 2 2| CLIENTS BRIEF HOUSING CHOICES AUSTRALIA The challenge issued by Housing Choices As social and affordable housing Australia in the Getting to Yes Studio delivered by a housing association Design Brief brief is to provide a residential design typically remains under management, solution for 25– 72 Stubbs Street, North consideration should be given not only Melbourne that provides a socially cohe- to immediate financial viability, but also sive insertion into the existing commu- to issues of ongoing maintenance and nity, whilst satisfying the requirements of management.
