Class N – Hard surfaces for schools, colleges, universities or hospitals
If you run a school or other educational facility or a hospital you may be able to create or replace a hard surface without the need for planning permission.
The maximum area within the curtilage of the site created after 6th April 2010 is limited to 50 sq m. You cannot hard surface a playing field if that area has been used as a playing field in the last 5 years. You are also prevented from using Class N in the curtilage of a listed building.
Unless there is a risk of groundwater contamination any new surfaces must be either prorous or provision made for the run-off water to be dealt with properly.
