PERMITTED DEVELOPMENT RIGHTS

Unless you live in a Listed Building, Conservation Area or Area of Outstanding Natural Beauty, you will not usually need to apply for planning permission if you do not exceed the permitted development rights for your property which is 50-70 cubic metres, depending on where you live:

DETACHED PROPERTIES & CONSERVATORIES

If you have a detached property, you will normally be allowed to develop up to 70 cubic metres, or 115‰ of the total volume of the property whichever is greater.

Example: A conservatory with external dimensions 4 metres wide, 4 metres deep and 4 metres high would normally be within your permitted development rights.

SEMI-DETACHED PROPERTIES & CONSERVATORIES

The same rule applies as it does to detached properties; you are allowed to develop up to 70 cubic metres, or 115‰ of the total volume of the property whichever is greater.

Example: A conservatory with external dimensions 4 metres wide, 4 metres deep and 4 metres high would normally be within your permitted development rights.

TERRACED & END-OF-TERRACE HOMES & CONSERVATORIES

The same rule applies as it does to detached and semi-detached, but you are restricted to developing up to 50 cubic metres, or up to 110‰ of the total volume of the property whichever is greater.

Example: A conservatory with external dimensions 4 metres wide, 3 metres deep and 3.5 metres high would normally be within your permitted development rights.

IMPORTANT: If your property has been extended in the past you will have used some of your permitted development rights, or perhaps all of them, and may need planning permission to extend further.
