Can I build a wall/to the front/to the back/or around my house without planning permission?

Yes you can build a wall of specified materials and to a certain height around and within the curtilage of your house without planning permission.
You can build a railing or wooden fence, or a wall of brick, stone, blocks with decorative finish, other concrete blocks or mass concrete.
Every wall (other than dry or natural stone) must be capped and the face of any wall of concrete or concrete block, which is visible from any road, path or public area, must be rendered or plastered.
A metal palisade or other security fencing cannot be used. If you wish to use this type of material, you need to apply for planning permission.
The height of any wall should not exceed 2m and any wall within or bounding the space in front of a house should not exceed 1.2m.
