surrounding walls in estates

Does anyone know if there is any regulations or procedures to building a surrounding wall around your house if you are living in an estate. my neighbour has built a wall around theres and now where i used to sit on a sunny evening i came home from work to find it completely in the shade because of this wall>????????

You can build a wall on or around your property, without planning permission,
so long as the height of the wall does not exceed 2meters.

How high was the wall your neighbour built?

1.2 metres to the front of a dwelling.

Planning permission for the initial build may have been for open plan development and walls may not be permitted to the front
