The built environment impacts health and wellbeing in many profound and complex ways. These include the impact of design and architectural elements on enabling and disabling users of buildings. Similarly, there is evidence to suggest that some of the materials used in construction might impact on health (e.g., Sick building syndrome). Some studies have also drawn our attention to impact of indoor environments on health and well-being, including noise, temperature, humidity and mould, light, air quality, lead paint. Whilst construction has improved its record on health and safety over the last 10-15 years, people’s mental health and wellbeing has been somewhat neglected. We now see workers more at risk of committing suicide than falling from height, and so while strides have been made in physical safety, mental health risks have not received the same level of attention until more recently. In the UK, for example, a quarter of construction employees have considered taking their own lives between 2011 and 2015 alone. Women in England are more likely to have a common mental health problem and male’s construction workers being 3 times more likely to take their own lives. There is ample scope for research (including international comparative research studies) in the area of welfare and wellbeing in the construction industry, especially with the impact of COVID- 19. This sub-theme encourages papers that addresses the impact of built asset has on construction workers’ wellbeing and that offers solutions that addresses the challenges associated health of construction workers.
