Understanding planning permission can sometimes feel confusing, particularly if you are planning a house extension, alteration or new development.
At HEAMES Architectural Drawings & Planning Consultants, we provide clear and practical planning permission advice for homeowners, property developers and businesses across Cardiff, South Wales, Bristol and the South West of England.
Whether you are considering an extension, new build, change of use or property conversion, we can help you understand what permissions may be required and guide you through the process.
What Is Planning Permission?
Planning permission is approval granted by your local planning authority that allows certain types of building work or development to take place.
The planning system exists to ensure that developments are appropriate for the surrounding area and do not negatively impact neighbouring properties or the local environment.
Planning permission is typically required for:
-
House extensions beyond permitted development limits
-
New build homes
-
Flat conversions
-
Change of use of a property
-
Alterations to listed buildings
-
Developments within conservation areas
Do I Always Need Planning Permission?
Not all building work requires planning permission.
Some smaller developments may fall under Permitted Development Rights, which allow certain works to be carried out without a formal planning application.
Examples may include:
-
Some rear house extensions
-
Loft conversions
-
Minor external alterations
However, the rules can be complex and vary depending on the property, location and previous developments.
Many homeowners choose to apply for a Lawful Development Certificate, which confirms that the work is permitted and can help avoid issues when selling the property in the future.
The Planning Application Process
The typical planning process involves several stages.
1. Initial Design and Advice
The proposed development is discussed and the feasibility of the project is assessed.
2. Architectural Drawings
Existing and proposed drawings are prepared to clearly show the development.
Planning Application Submission
3. Planning Application Submission
The application is submitted to the local planning authority along with the required drawings and documents.
4. Planning Assessment
The planning authority reviews the proposal and may consult neighbours and other departments.
5. Planning Decision
Most planning decisions are issued within approximately 8 weeks.
