What are the Permitted Development Rights?
Permitted development rights is a scheme of the Government of the UK that allows you to extend or renovate your house without any permission from the local authorities.

- Change of use
- small extension
- new doors
- Garage conversions
- Small porch construction
- new doors
- solar panels installation
- Satellite dish installation
- Basement conversions
However, it is important to remember that these rights are subjected to certain limitations and conditions set by the government. That is why it is important to verify your permitted development rights before commencing the work to avoid any legal conflict.

Following are the areas that are excluded from the permitted development scheme:
- conservation areas
- National Parks
- World Heritage Sites
- the Broads

What are the Rules for House Extensions in 2023?
The house extension rules are not particularly complex to navigate through. Depending upon the following factors, there are different sets of rules for building a house extension:
- Type of the house you own
- The type of extension you want to build.
Following are the different sets of rules depending upon the type of the house:
Rules for Single-storey Extensions:
- The enclosed area cannot exceed half of the surrounding property beyond the original house.
- Extensions in front of side elevations or facing a highway are not permitted without planning clearance.
- Exterior cladding is prohibited on buildings located in designated land areas.
- A single-storey rear extension cannot project more than four meters beyond the original property’s back wall.
- The maximum height for a single-storey extension is four meters.
Rules for Two-Storey Extensions:
- Extensions cannot extend more than three meters past the back wall for two-storey homes.
- If within two meters of the boundary, the extension’s eaves cannot exceed three meters.
- The ridge and eaves of the extension cannot be higher than the current structure.
- A minimum distance of seven meters must separate the two-storey extension from the rear borders.
- The roof pitch should match the existing property or be as close to it as possible.
- Verandas raised platforms or balconies in the extension require planning approval.
- Obscure-glazed windows that cannot be opened must be installed in the roof slope or side elevation wall.
- Two-storey additions do not have permitted development rights for specified land.
- The extension’s façade must use materials similar to those of the main house.
Rules for Side Extensions:
- Side extensions in single-storey buildings must not exceed a height of four meters.
- The width of a single-storey side extension should not exceed more than half of the existing house’s width.
- Side extensions are not allowed on houses located in designated land areas.
Rules for Rear Extensions:
- Single-storey rear extensions can extend up to four meters beyond the existing house’s rear wall.
Rules for Terraced and Semi-Detached Houses:
- Terraced or semi-detached houses can be extended by up to three meters without requiring a permit under approved development.
- Applying for a lawful development certificate is recommended, either before or after construction, to confirm compliance and allow for potential property sales within four years of completion.
Rules for Detached Houses:
- Permitted development allows for a maximum extension of up to four meters for detached houses.
- Eligible cases may qualify for extensions of up to eight meters under the larger house extensions program.
How Far A House Extension Can Go Without Planning Permission?
The permitted development scheme was actually developed during the pandemic of 2020 to allow homeowners to extend their houses due to the increased demand for space in the houses. However, it is important to know that these rights only apply to houses and flats, and maisonettes are excluded from the list.
Depending upon the type of house and the extension you are planning to build, there is a specific allowed limit for you to extend the footprint of your house. However, you cannot completely change the shape of your front elevation without planning permission.
It is recommended to engage an experienced house extension contractor or an architect who can help you through the rules and regulations.
What to Consider before starting a House Extension Project?
Planning and Permits: Check with local authorities to understand the planning regulations and permits required for the type of extension you are considering. Ensure you comply with all building codes and zoning laws.
Budget: Determine your budget for the extension project, including construction costs, design fees, permits, and potential unexpected expenses.
Design and Functionality: Work with an architect or designer to create a well-thought-out design that complements your existing home and meets your functional needs. Consider factors such as layout, natural light, and accessibility.
Property Restrictions: Be aware of any restrictions on your property, such as easements, utility lines, or protected trees, which may impact the extension’s location and design.
Impact on Neighbours: Consider how your extension might affect your neighbours, both during construction and after completion. Ensure your plans are respectful of their privacy and property.
Timeframe: Understand the projected timeline for the extension project, including design, permits, construction, and any potential delays.
Disruptions and Living Arrangements: Plan for any disruptions to your daily life during construction and consider temporary living arrangements if needed.
Future Plans: Think about how the extension aligns with your long-term goals for the property and whether it adds value to your home.
What Happens If You Do Not Comply with House Extension Regulations?
Although it may seem that the building codes and house extension rules are tough and nerve-wracking to follow, they are an essential part of any construction. Make sure you adhere to them completely, along with your architect and house extension contractor, to avoid any unpleasant circumstance that may cost you in terms of time and money.
If you fail to comply with the regulations, you may face severe legal issues combined with penalties. The authorities can ask you to remove the extension, which will cost you the amount of constructing the extension and demolishing it. You will also face difficulties in selling your house if the house extension does not comply with the local codes. Local authorities can also take legal action against you, resulting in a fine or any other legal proceedings.
