The government recognises the valued role mansard roof development can play in supporting urban intensification. The National Planning Policy Framework is clear that national policy supports all types of upwards extensions, including mansard roof development, and encourages their approval in areas or building types where this is appropriate and meets adopted or emerging local policies and design codes that require development to be well designed.
