What Are Article 4 Directions?

Normally certain minor works can be carried out without the need for a planning application. These are called permitted development and the rights relating to them are defined in the Town & Country Planning (General permitted development) Order 1995. Some areas, and some buildings, are particularly susceptible to harm caused by a succession of small changes - things that otherwise might be of no consequence, as a means of extra control to ensure the character and appearance is not unduly impacted, an Article 4 Direction can be applied by a Local Authority to remove some of these rights.

Such a Direction means that certain alterations to buildings which would have normally been allowed under permitted development rights have been brought under planning control and planning permission must be sought.

There is no fee for any planning application required solely by an Article 4 direction.

Article 4's in Powys

Within Powys (outside of the Brecon Beacons National Park) there are currently five Article 4 Directions relating to built heritage. Article 4(2) directions apply to Llanidloes, Knighton, Machynlleth and Presteigne while an Article 4(1) is in force in Llandrindod Wells.

The maps are interpretations of the definitive Article 4 maps held by the County Council. Whilst every effort has been made to ensure that these maps are accurate, they are not the definitive maps, which should be consulted in any cases of doubt.

Works covered by the Directions

Article 4(2) Directions

An Article 4(2) Direction can cover, for example, the following classes of development where they would front a highway (including a footpath used by the public), waterway or public open space. In Powys, individual article 4(2) directions have been applied to address the particular needs of individual conservation areas. Therefore different restrictions apply in different areas - so if you are planning any of these types of works it is best to contact planning services to find out if you need planning permission.

In respect of a dwelling house:
  • The enlargement, improvement or other alteration;
  • Any alteration to the roof;
  • The erection or construction of a porch outside any external door;
  • The provision within the curtilage of a dwelling house of a hard surface;
  • The provision within the curtilage of a dwelling house of a building, enclosure or swimming pool;
  • The installation of a satellite antenna;
  • The erection, construction, maintenance, improvement or other alteration of a gate, fence, wall or other means of enclosure;
  • The erection, alteration or removal of a chimney (whether or not it fronts a relevant location).
In respect of any building:
  • The painting of the exterior of any building or work in so far as it involves the application of paint to any previously unpainted wall;
  • Any building operation consisting of the demolition of the whole or any part of a gate, wall or other means of enclosure;

Article 4(1) Directions

These work in much the same way as Article 4(2) Directions but the controls in place affect all parts of a property and not just those facing onto a highway or public open space. In Powys only Llandrindod Wells Conservation Area is covered by an Article 4(1) Direction.
