本主题探讨了住房市场中最弱势和被排斥的群体（如无家可归者，逃离家庭暴力者，新移民，年轻人，前犯罪者，有滥用药物问题的人以及因反社会行为而失去家园的风险）。一项广泛的工作计划集中于“街头文化”活动，例如，粗暴睡眠，乞讨，街头饮酒，街头卖淫和“幸存”犯罪（例如入店行窃）。旨在改变无家可归者生活方式的“干预主义者”服务方法的道德基础一直是重点研究重点，也是社会控制机制（例如ASBO）用于“管理”街头人口的关键。
This theme explores the experiences, needs and perspectives of the most vulnerable and excluded groups in the housing market (such as homeless people, those fleeing domestic violence, new migrants, young people, ex-offenders, people with substance misuse problems, and those at risk of losing their home through anti-social behaviour). An extensive programme of work has focused on ‘street culture' activities, for example, rough sleeping, begging, street drinking, street prostitution, and 'survival' crimes (such as shoplifting). The ethical basis for ‘interventionist' service approaches which seek to change homeless people's lifestyles has been a key research focus, as well as the use of social control mechanisms (such as ASBOs) to 'manage' street populations.
