Risks in domestic basement construction (NF4)


The use of basements is being increasingly considered as an option by builders and developers to address Government targets on housing supply and planning density, alongside a growing demand from consumers for family housing. Basements have inherent risks relating to water ingress and load-bearing capacity and the guide is designed to clarify risk management issues that should be considered in the construction process.

Post-publication note: NHBC has published specific guidance on the construction of basements. It is recommended that you read Chapter 5.4 of the 2016 NHBC Standards if considering the inclusion of a basement in your design.
