This article reviews developments over the past ten years which have led to an increase in architectural and technological defensiveness of both individual homes and of neighbourhoods. It argues that this is the result of a combination of prevailing structural conditions: neoliberal state policies that bolster responsible home ownership and aim to reduce public spending; an emphasis on the market which opens the way for developers and the security, insurance and associated industries to make profits; loss of place-based community which cannot be replaced by the legal frameworks which bind the residents of private enclaves; an increase in house prices causing homes to be viewed primarily as financial assets; fear of crime fuelled by the media; and a lack of government policies to prevent the further growth of gated communities.Keywords: defended homes; gated communities; tessellated neoliberalism.The editors' invitation gives me an opportunity to reflect on gated communities and their societal effects over the past decade, both in the context of a generally more fearful and individualistic attitude to the home and in the context of the economic and ideological policies and forces associated with this trend. In the ten years since my paper 'Gated communities in England as a response to crime and disorder' was published in PPP, this form of housing has proliferated across the world. Research into gated communities and the issues they raise has followed suit, and there are now so many relevant publications that it would be impossible to cite them all here. Much of this research has been descriptive and very context-specific, but there have been some comparative publications which help us to understand the different drivers for the spread of gated communities in different countries, and to consider whether it is possible to draw any general conclusions (see, for example, Bagaeen and Uduku, 2015). Rowland and I then started to notice that many single homes were becoming fortified. As well as enclosed housing developments behind barriers, with legal arrangements for self-governance (i.e. gated communities), many ordinary suburban homes now display security features such as lockable electronic gates, spike-topped walls and fences, internal and external iron grilles at the windows, burglar alarms and CCTV. The concept of defensive homeownership was developed for our recent book (Atkinson and Blandy, 2017) and I will draw on some of those ideas to argue that fortress homes and
