Creating Inclusive Communities through Balancing Social Mix: A Critical Relationship or Tenuous Link?

This paper explores some fundamental assumptions being linked by State Housing Authorities to 'social mix' strategies in contemporary Australian public housing estate regeneration policy. Six case-study estates, two each in New South Wales, South Australia and Queensland form the basis for the empirical analysis. The two major ideas emerging from South Australian and Queensland projects are: first that lowering concentrations of public housing and developing more mixed income communities offers a means to reconnect socially excluded public housing tenants to mainstream society; second that a balanced social mix is a prerequisite for the development of 'inclusive', 'sustainable' and 'cohesive' communities. However, in light of the empirical findings that strong cohesive communities already exist on some estates prior to regeneration commencing, there is no evidence that a balanced social mix is a necessary condition for building inclusive communities. Coupled with findings in the projects of inadvertent negative consequences of implementing social mix policies, the paper questions whether policy makers are over-emphasising the extent to which social mix assists regeneration.     

The future of Dutch housing associations

This paper discusses the future of the social rented sector in the Netherlands. There are several reasons why the position of this sector is currently under close scrutiny. Whereas attention to social rented housing had lapsed by the start of this century, the growing housing shortage and stagnation in the restructuring of older urban areas brought this sector back into the political spotlight. Also the European Commission is having a major impact on the future position of the sector. The Commission has ordered the Dutch Government to establish a level playing field by abolishing the privileges of the housing associations. Against this background, this paper discusses the possible tasks and proper functioning of the Dutch housing associations.     

New River Village

Social affordable housing is so often the poor relation of any private development, allocated the poorest plot with the least attractive aspect. Bruce Stewart describes how at Hornsey in north London, Stock Woolstencroft has transcended these problems with considerate spatial organisation and security management.

荷兰住房协会——社会住房建设和管理的非政府模式

荷兰社会住房比例在全欧洲最高,其社会住房主要由住房协会建设和管理.文章追溯了住房协会的发展历程以及对荷兰政府不同住房政策的反应,总结了住房协会的双重二元特征:私人机构但是却承担了公共责任,是资金来源于政府的NGO组织.在1990年代资金独立之后,公共使命和从事市场活动成为了住房协会新的特征.文章还分析了住房协会在与政府、协会之间以及居民的关系中所扮演的的不同角色,反映了其各项职能.此外,对荷兰住房协会管理的模式进行了总结和反思,以期对我国的保障性住房建设提供借鉴和思考.
