High-rise development and densification are tools used by planners to achieve social and environmental goals within increasingly populous urban areas. This study aims to explore the impacts that these processes can have on residents in the neighbourhoods they are occurring in. The project employs a mixed-method approach with both quantitative and qualitative processes. This methodology will be applied to the case study: residents on the Isle of Dogs. The Isle of Dogs is a neighbourhood located in London, England that has undergone intense high-rise development and regeneration. The study involved a quantitative survey of 49 residents and 7 participants from the survey volunteered to do a walked interview. The study focused on residents’ perceptions of densification and high-rise development. The findings indicate that residents primarily felt opposed to high-rise development and densification and felt their lives and the neighbourhood were both negatively impacted by factors relating to development such as infrastructure stress and loss of community. There was a geographic divide, with residents of newer high-rise towers on the Isle feeling less negatively about development. Residents also felt a lack of agency over the impact of development and densification in their neighbourhood. The additional pressures that densification places on infrastructure is the primary cause for resident's negative perceptions of development. This current study proposes that there is a need for a balance between new development and infrastructure pressure and this is key to ensuring residents are not negatively impacted and therefore more accepting of development.
