Tenure restructuring to produce mixed communities as a replacement or adaptation of existing mono-tenure, social housing areas, became an important urban development and regeneration strategy over the past 20 years, is expressed in governmental statements and in planning guidance, and is a key component of housing policy. Through a range of impacts - on individual and group behaviours, on community functioning, on the reputation of a place, on housing and environmental quality, and on the local economy and services, mixed-tenure communities are intended to be more sustainable into the future (see Kearns and Mason, 2007 for a review). However, it is still unclear whether and how such benefits can be achieved merely through tenure diversification. Primary evidence on effects of tenure mix in the United Kingdom, published from 1996 to 2009, is very weak (authors’ systematic review in progress). While families’ wellbeing is one of key elements of urban sustainability, very few studies focus on outcomes of tenure mix for families. This paper presents two qualitative studies, which explore: 1)resident families’ perceptions of living in mixed tenure areas, and 2)professionals’ views on tenure diversification process and its outcomes for resident families. This research is part of GoWell, a programme that aims to investigate the impact of investment in housing, regeneration and neighbourhood renewal on the health and wellbeing of individuals, families and communities over a ten-year period in Glasgow, United Kingdom. Our research focuses on three estates in Glasgow: Gorbals, Castlemilk and Drumchapel. At the end of the 1970s, the three estates have been designated as multiple deprivation areas. From the end of the 1980s, they have been experiencing major regeneration and redevelopment processes, including tenure diversification. Today, some parts of these estates are still among the most deprived in Scotland (SIMD, 2009). In the first study, through semi-structured interviews with 37 heads of households having children in school age, we explore residents’ perceptions regarding: wellbeing of families, social cohesion, social norms, area reputation, quality of amenities, environment and housing. This study also investigates whether such perceptions differ depending on the degree of spatial integration of tenures which varies from integrated design when different tenures coexist in the same street, to segregated design with clusters of monotenure. The second study consists of interviews with 15 professionals working on these estates, e.g., urban planners, managers of housing associations and regeneration agencies, head teachers of local schools. Semi-structured interviews explore the history of redevelopment and tenure diversification in the estates, successes and challenges of tenure mix introduction, inter-relationships between physical and social outcomes of tenure mix. Presentation of study results will be followed by a discussion of their implications for housing policy and understanding of effects of urban regeneration.
