Urban Community Land Trusts (CLTs) have been acclaimed for their politically transformative potential: de-commodifying land and providing permanently affordable housing under community control. Few studies include CLT residents and this paper features two case studies to help fill the gap. St Clements in East London, UK, and Citizens House, Southeast London, both created by London CLT, collectively have 34 households living in them. Unlike more geographically focused CLTs, London CLT provides governance, knowledge, and skills to support people across London to build the affordable housing they campaign for. The selection criteria prioritised the needs of those failed by the existing housing market, who had long-standing connections to the borough, and contributed to community life. London CLT hoped residents would have a transformational impact on the neighbourhood, spreading the ethos of community control. Using the conceptualisations of territorialisation and conviviality, new knowledge has been produced about residents’ experience of negotiating shared lives. While residents are happy with their homes, and value the neighbourliness that comes from knowing others better, investing time and energy in more organised activity and decision making has been slow. The two spaces display both the affectivity and distancing associated with territorialisation and the ‘rubbing along’ and ambivalence of conviviality.
