The construction, demolition and excavation waste arising in the UK is estimated at 109 million tonnes per year. Much had been published on ways to improve on-site waste management and recycling activities but very few attempts made to address design generated waste. This paper examines previous studies on architects’ approach towards construction waste minimisation; and by means of a postal questionnaire sent to the 100 top UK architectural practices, investigates: the origins of design waste; waste minimisation design practices in the UK; and barriers to design out waste. The findings reveal that architects consider that waste is mainly produced during site operations and rarely generated during the design stages. However, about one third of construction waste could essentially arise from design decisions. Results also indicate that a number of constraints, namely: lack of interest from clients and attitudes towards waste minimisation are seen as disincentives to a proactive and sustainable implementation of waste reduction strategies during the design process.
