Planning Policy Statement 3 makes clear that local authorities should set their own density targets. Local authorities may decide, based on the particular circumstances of their area, or a part or parts of it, to plan for, or agree to, densities different from the national indicative minimum 30 dwellings per hectare in Planning Policy Statement 3 (PPS3). For example, higher densities may be more appropriate in town centres, and lower densities in rural villages or areas of historical importance.
