Planning Permission for Porch

Porches add extra warmth and security to a home and they can also increase a property’s appeal and value.
If you want to build a porch onto your home you are free to do so without planning permission. Porches are considered to be permitted development and so long as your home is not a listed property, building a porch is as simple as buying the bricks.

There are however a few conditions and limits that govern the permitted development of porches. If you are likely to exceed any of these limits, planning permission will be needed:

  1. Ground floor porches must not exceed three square metres measured externally.
  2. Porches must not exceed three metres in height.
  3. Porches must not be within two metres of any boundary or dwelling on the highway.

So long as the above conditions are met, you are welcome to build a porch onto your property. If you are in doubt or you are unsure of your individual circumstances, we recommend that you consult with your Local Planning Authority who will be able to offer guidance.

Listed building

Although porches are permitted development for the vast majority of homes, listed building owners may need to request listed building consent before building one. This will be granted only if your development plans do not negatively alter the character, appearance and structure of your home. Building a porch onto a listed building without consent is a criminal offence. Always ensure that you require and have listed building consent prior to carrying out any work.

Designated areas

Depending on where your property is located, you may need to apply for planning permission to build a porch if you are in a designated area, such as a National Park or an Area of Outstanding Natural Beauty. Although permitted development does apply in designated areas, we strongly recommend that you consult with your Local Planning Authority just to make sure.
