Understanding Permitted Development Rights
Introduction
Navigating the regulations for home alterations can be challenging. General Permitted Development Rights (GPDO) provide homeowners with the liberty to modify their properties without planning permission. However, it's crucial to note that legislation for internal changes, especially within a residential dwelling's curtilage, may differ.
What are Permitted Development Rights? Permitted Development Rights (PDR) provide homeowners with the ability to carry out certain types of work without the need for planning permission. These rights are subject to specific criteria and limitations. Below are examples of permitted development rights for residential properties, categorised under various classes from Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015. It is important to note that Permitted Development Rights (PDR) for residential properties generally do no apply to flats or maisonettes PDR primarily apply to single-family homes.
Class A: Extensions and Improvements
Single-Storey Rear Extensions:
- Detached Houses - Extend up to 8 metres from the original rear wall.
- Other Houses - Extend up to 6 metres from the original rear wall.
- Conditions - Must not exceed 4 metres in height; materials should match the existing house.
Side Extensions:
- Up to 50% of the width of the original house.
- Must be single-storey and no more than 4 metres in height.
- Should not extend beyond the front elevation of the house.
Class AA: Additional Storeys
Upward Extensions:
- Adding up to two additional storeys on houses of two or more storeys.
- Adding one additional storey on single-storey houses.
- Conditions: The extension must not exceed the height of the existing house by more than 3.5 metres; materials should match the existing house.
Class B: Additions to the Roof
Loft Conversions:
- Add dormer windows or roof lights.
- Increase roof space by up to 50 cubic metres for detached/semi-detached houses and 40 cubic metres for terraced houses.
- Conditions: Dormers should not extend beyond the plane of the existing roof slope on the principal elevation.
Class C: Other Roof Alterations
Rooflights and Skylights:

Class D: Porches

Class E: Outbuildings and Sheds
Garden Buildings and Sheds:

Class F: Hard Surfaces
Hardstanding for Vehicles:
- Create a hard surface for parking within the curtilage of the house.
- Conditions: Must be porous or provision must be made to direct runoff water to a permeable or porous area within the curtilage.
Class G: Chimneys, Flues, and Soil and Vent Pipes:
Chimneys and Flues:

Class H: Microwave Antennas
Satellite Dishes:

- Conditions: Dish must not exceed 1 metre in diameter and must not be installed on a chimney, wall, or roof slope fronting a highway.
Considerations and Restrictions:
- Listed Buildings and Conservation Areas: Properties in conservation areas or those that are listed buildings face additional restrictions. For these properties, certain Permitted Development Rights (PDR) may not apply, or extra permissions might be necessary.
- Article 4 Directions: Local authorities have the power to remove specific permitted development rights in designated areas through Article 4 Directions, which necessitate planning permission for changes that would typically be allowed.
- Building Regulations: Compliance with building regulations is mandatory for all projects, even those that fall under permitted development, to ensure that safety and quality standards are upheld.
Understanding these examples and their associated conditions can help homeowners navigate their renovation and improvement projects more effectively, fully utilizing their permitted development rights. These are a few examples of the Permitted Development Rights available for residential properties.
