Rapid growth in the production of new homes in the UK is putting build quality under pressure as evidenced by an increase in the number of defects. Housing associations (HAs) contribute approximately 20% of the UK's new housing supply. HAs are currently experiencing central government funding cuts and rental revenue reductions. As part of HAs' quest to ramp up supply despite tight budget conditions, they are reviewing how they learn from defects. Learning from defects is argued as a means of reducing the persistent defect problem within the UK housebuilding industry, yet how HAs learn from defects is under-researched. The aim of this research is to better understand how HAs, in practice, learn from past defects to reduce the prevalence of defects in future new homes. The theoretical lens for this research is organizational learning. The results drawn from 12 HA case studies indicate that effective organizational learning has the potential to reduce defects within the housing sector. The results further identify that HAs are restricting their learning to focus primarily on reducing defects through product and system adaptations. Focusing on product and system adaptations alone suppresses HAs' abilities to reduce defects in the future.

Purpose: Research on housing defects has limited its enquiry to the classifications of defects, potential impact of defects, and their detection and remediation during construction and the builder's liability period, without considering the warranty period. This paper aims to better understand which impacts of defects are perceived as important by the key stakeholders involved in their detection and remediation over the construction, builder's liability and insurer's warranty periods. Design/methodology/approach: The questionnaire survey approach was used. The questionnaire distribution list was drawn from the UK's largest warranty provider and approved inspector's records. The questionnaire was distributed to 2003 people, receiving 292 responses, a response rate of 15%. Findings: This research challenges the assertion that the house building industry (i.e. house builders, building inspectors and warranty providers) is predominantly cost focused and finds that the potential impact of defects on home occupants are their primary concern. In contrast, the home occupants' appear solely focused on the disruption defects caused on their daily lives and perceive a lack customer focus in the house building industry. Originality/value: This study provides empirical evidence of the contrasting view of the house building industry and home occupants with respect to the prioritisation of the impacts of defects. Further, this research offers house builders an alternative approach to determine which defects should be targeted for reduction purposes which may lead to improved levels of customer satisfaction.

Purpose Maximising the benefit of learning from defects is regarded by UK housing associations (HAs) as a key opportunity to meet their challenges of building more homes with reduced government funding and rent incomes. Despite learning from defects being a frequent recommendation to reduce defects in the construction literature, there is scarce empirical evidence into how HAs actually learn from defects. The purpose of this paper is to better understand how HAs learn from past defects and induce change to reduce defects. Design/methodology/approach Guided by organisational learning (OL) as the theoretical lens, a 21-month action research (AR) project explored one HA’s defects management and learning processes. Findings OL has the potential to reduce defects in new homes but is a secondary task which is reliant on a defects management team analysing defect data to identify priority areas. As such, learning from defects can be reduced due to peaks in workload if data analysis is a manual process. Furthermore, a dual learning approach plays a significant role for HA’s learning consisting of designing out defects (codification) supported by networking (personalisation) to tackle issues of workmanship on site and those defects that cannot be designed out. Originality/value This study demonstrates OL has the potential to reduce defects in new homes but is a secondary task in HA’s practice; and highlights the practical challenges of academia and industry co-production in AR in construction.
