Living in a conservation area
There are national planning controls if you own a property which is in a conservation area and guidance on the rules can be found on the Planning Portal.
Most homeowners have certain permitted development rights which means they do not have to apply for planning permission for certain works. In conservation areas, some of these rights are removed which is referred to as an Article 4 Direction, which give additional controls over various minor alterations, such as alterations to windows.
Further information can be found on our Article 4 direction section.
There are three conservation areas that have Article 4 directions served, namely Bute Town, Pontywaun Garden Suburbs in Crosskeys and Rhymney Town.
Do I need permission to do work to a property in a conservation area?
The most common types of works in conservation areas that requires planning permission include:
- adding external wall insulation
- cladding any part of the house with stone, artificial stone, pebble dash, render, timber plastic, metal or tiles
- any works that will alter the external appearance of your property such as extending your roof, or installing, altering or removing a chimney stack, etc.
- single-storey side extensions are only permitted if they project from the side elevation of the original dwellinghouse by less than 3 metres and are set back from the principal elevation of the original dwellinghouse by at least 1 metre
- extensions of more than one storey
- demolition or the almost total demolition of an unlisted building
- installing satellite dishes, t.v. and radio aerials
- altering or removing some boundary walls or hedges
- altering vehicle access or parking arrangements around the property
- works to trees within conservation areas such as felling, pruning, cutting, lopping or topping to any trees or shrubs with a stem diameter measuring over 75mm (at chest height). For more information see our section on tree preservation orders.

Heritage impact assessment
Heritage impact assessment is a structured process to make sure that you take the significance of your historic asset into account when you are developing and designing proposals for change.
As from 1 September 2017, a heritage impact statement is required to support an application for conservation area consent.
A heritage impact statement for conservation area consent must contain:
- a description of the proposed works (“the demolition works”), including a schedule of works;
- an explanation of the objective that the demolition works are intended to achieve and why demolition is desirable or necessary;
- a description of the contribution any building which is proposed to be demolished makes to the character or appearance of the conservation area;
- an assessment of the impact of the demolition works on the character or appearance of the conservation area, including a description of any potential benefits or harm to the character or appearance of the area;
- a summary of the options considered for the purpose of achieving the objective referred to in paragraph (3) (b) and the reasons why demolition is preferred.
Guidance on preparing a heritage impact statement can be found here Heritage Impact Assessment in Wales (PDF)
Further guidance is available from Cadw’s website
Design and access statements (DAS)
The requirement to submit a DAS with a planning application in a conservation area will apply to:
- development of one or more dwellings
- where the creation of floorspace is 100 sq. m. or more
For further guidance on how to produce a DAS please download the Welsh Government’s Design and Access Statements in Wales, June 2017 (PDF)
