Research reveals stark risks of flooding in subterranean spaces

I wanted to find out about UK policy, British Standards and codes of practice relating to the conversion of basements into habitable flats. I interviewed key people from the Environment Agency, Property Care Association (PCA), Department for Environment, Food and Rural Affairs (Defra), Construction Industry Research and Information Association (Ciria), fellows of the Chartered Institution of Water and Environmental Management (CIWEM) and CEOs in the flood and basement conversion industries.
