Conservation Area Information

Planning Permission in a Conservation Area

Conservation Area designation introduces some extra controls to protect the special qualities of the area. This means that planning permission may be required for certain work, that outside of a Conservation Area would normally be classed as 'permitted development'. Once an area is designated a Conservation Area, the Local Planning Authority has a duty to advertise proposals that may affect it, by site notice and in the local press, so that public opinion can be obtained. Applications for 'outline' planning permission in a Conservation Area may often not be appropriate, and more comprehensive information of a proposal may be required in order to properly assess the impact of the scheme on the special qualities of the Conservation Area.

Commercial properties (including flats and apartments) whether located in or outside of a Conservation Area have limited permitted development rights i.e. works that can be carried out to the property without planning permission and therefore planning permission is often required.

Residential properties have certain permitted development right, i.e. works that can be carried out to the property without planning permission. However within a Conservation Area these permitted development rights (PD) are more limited.

In addition to normal planning controls, Planning Permission will be required in a Conservation Area for the following works, which affect a residential property (dwelling-house):

  • An extension to the dwelling-house which would extend beyond a wall forming a side elevation of the original dwelling-house.
  • An extension of the dwelling-house which would have more than one storey and extend beyond the rear wall of the original dwelling-house.
  • The cladding of any part of the exterior of the dwelling-house with stone, artificial stone, pebble-dash, render, timber, plastic and tiles.
  • The enlargement of a dwelling-house consisting of an addition or alteration to its roof.
  • The provision within the curtilage of a dwelling-house of any building or enclosure, swimming or other pool required for such a purpose incidental to the enjoyment of the dwelling-house as such, OR the maintenance, improvement or other alteration of such a building or enclosure: OR a container used for domestic heating purposes for the storage of oil or liquid petroleum gas IF

    - any part of the building, enclosure, pool or container would be situated on land between a wall forming a side elevation of the dwelling-house and the boundary of the curtilage of the dwelling-house OR,
    - if in a World Heritage Site, the total area of ground covered by buildings, enclosures, pools and containers situated more than 20 metres from any wall of the dwelling-house would exceed 10 square metres.
  • The installation, alteration or replacement of a chimney, flue, or soil and vent pipe on a dwelling-house IF the chimney, flue or soil and vent pipe would be installed on a wall or roof slope which fronts a highway and forms either the principal or side elevation of a dwelling-house.
  • The installation, alteration or replacement of a microwave antenna (satellite dish) on a dwelling-house*, or within the curtilage of a dwelling-house IF it would consist of the installation of an antenna:

    - on a chimney, wall or roof slope which faces onto, and is visible from, a highway or
    - in the Broads, on a chimney, wall or roof slope which faces onto, and is visible from a waterway; or
    - on a building which exceeds 15 metres in height.

Installation of Domestic Micro-generation Equipment

In addition to normal planning restrictions Planning Permission will be required in a Conservation Area for:

The installation, alteration or replacement of solar thermal equipment on:

  • A dwelling-house* or
  • A building situated within the curtilage of a dwelling-house IF the land is within a Conservation Area or a World Heritage Site, and the solar PV or solar thermal equipment would be installed:
    • on a wall forming the principal or side elevation of the dwelling-house and would be visible from the highway; or
    • on a wall of a building within the curtilage of the dwelling-house and would be visible from a highway.

*in this case, the definition of a dwelling-house includes a building which consists wholly of flats or which is used as a dwelling-house.

  • The installation, alteration or replacement of stand alone solar within the curtilage of a dwelling-house IF
    • In the case of land, within a Conservation Area or a World Heritage Site, it would be situated within any part of the curtilage of the dwelling-house and would be visible from the highway.
  •  The installation, alteration or replacement of a flue, forming part of a biomass heating system on a dwelling-house IF
    • In the case of land within a Conservation Area or a World Heritage Site, the flue would be installed on a wall or a roof-slope forming the principal or side elevation of the dwelling-house and would be visible from a highway.
  • The installation, alteration or replacement of flue, forming part of combined heat and power system, on a dwelling-house IF
  • In the case of land within a Conservation Area or within a World Heritage Site, the flue would be installed on a wall or a roof-slope forming the principal or side elevation of the dwelling-house and would be visible from a highway.

Planning Permission (Demolition)

Planning Permission is required for proposed demolition within a Conservation Area. The total or substantial demolition of a building (in excess of 115 cubic metres) requires Planning Permission, as does the removal of certain walls, gates and fences. Generally this is in relation to, where planning permission would be required to erect such a wall, gate or fence. Any building proposed for demolition will be assessed as to whether it is considered to make a 'positive' contribution to the Conservation Area. If it does make a positive contribution, then its proposed demolition will be treated as if the structure was a listed structure and may, therefore be resisted by the District Council. Any proposal for demolition in a Conservation Area will need to be comprehensively justified.
