What is Planning Permission and when it is needed? 

The approval or consent given by a local authority for a building project to go ahead is called planning permission, and this consent is in place to eliminate illegal and inappropriate development.

Planning permission is usually required when you plan to go for new build, home extension or any major change to the property.

Decisions regarding planning permission grant are decided on the basis of national policies set by National Planning Policy Framework and local policies set by local authorities.

The planning application should be filed to and granted by your LPA (Local Planning Authority) before you plan to begin the construction work.

Is Planning Permission Really Important for new builds? 

Yes, it’s crucial for every new build to apply for the planning permission.

Where you carry out a project without getting a permit from the LPA, there is a big chance that you will be served an enforcement notice to undo all the alterations you made.

Ignoring the enforcement notice is considered illegal and may invite penalties, fines and even prosecution.

In fact, no professional builder will touch your new build without the necessary rights and approval from the LPA.

How to Get Planning Permission for new builds in United Kingdom?

To get planning permission, you need to submit an application to the Local Planning Authority (LPA) via your local council either in person or online.

There are two types of planning permission you may seek or new build homes:

1. The Outline Planning Permission:

This doesn’t give you the approval to begin work.

The basic idea is to test if your project will be given consent, meaning that this permission grants license in principle since no design specifics were included in the application.

2. The full Planning Permission:

Gives you the right to begin work, and it covers the entire detail/plan of your new build, and you must follow the detailed plan on paper to the letter.

If there is a chance that your building will deviate from the initial design, you will need to submit it for full planning.

How to apply for planning permission?

The application for planning permission can be applied online or you can contact the local authority office.

You can easily fill the form yourself or take help of any agent to do that for you.

You need to submit all your proposed plans such as layouts, floor plans, elevations etc that details out your proposed plan.

It will take usually 8 weeks for the Local authority to process your application.

The LPA may reach out to your neighbours asking for opinions or any objections. So, it’s always better to take your neighbours informed and in confidence.

Other Planning Considerations

Apart from informing your neighbours, there are several other considerations/approvals that you need to consider along your planning permission.

These may include:

  • Working on your design and understand how it may look on the street or in the surrounding landscape.
  • It should not pose any kind of disruption or hindrance to normal public activity.
  • The new design of the property should not encourage crimes such as burglary.
  • You need to make sure that there are no restrictions posed to the title of the property. Also, there aren’t any suspicious clauses in the lease agreement.

What is Included in a Planning Permission Application?

  • Copies of the application form (5)
  • Signed ownership certificate
  • Detailed building plan (block plan, site plan, elevations)
  • Access and Design Statement
  • Drainage information
  • Application fee

What Happens After You Apply?

Usually, it takes eight weeks to know if your application was approved or not.

During this period, a public consultation process occurs so people who can be impacted by the plans can comment.

There are certain factors known as material consideration that the local authority bases its decisions on;

  • Loss of privacy
  • Overshadowing
  • Parking
  • Traffic
  • Highway safety
  • Noise
  • Impact on conservation areas and listed building
  • Layout
  • Density of building
  • Government policy
  • Previous decisions

What if My Application is rejected?

There are two things you can do from here;

  • You can either make the changes and come to an agreement with the Local Authority
  • You can appeal the decision.

To help you manoeuvre these treacherous waters, you can ask for help from a planning officer or leave your application in the hands of your builder.

Since they build a lot, they know how to navigate the waters and make the dream home you want.

How much does it cost to get planning permission for a new build?

Depending on the complexity of the application, the LPA (local planning office) decides the application fee.

The fee details will be shared with you before submission of application is that you can reconsider whether to apply or not in case you are still not sure.

How long does it take to get planning permission for a new build?

Usually the application process takes around 8 weeks to get fully completed but the time may vary depending on the complexity of the project.

Apart from that, gaining planning permission doesn’t mean that you can kick start your work immediately.

Make sure to comply by all the conditions that are attached with the planning permission consent.

For how long planning permission is valid?

Usually, the planning permission consent is valid upto three years from the date it has been granted.

Else, it would be mentioned in the consent itself.

What Things to consider before starting extension?

Will the home extension add value to my home?

Assessment might be bit complicated if you’re planning to do it yourself.

Therefore, look out for some nearby properties that have undergone the same process or approach good home extension builders near me for better assessment.

Falls in your Budget

Stages of Home Extension

Stages of Home Extension

Home extension is a perfect way that helps you cook, eat together, work, exercise, entertain and much more at one single place.

Working properly on house extension ideas and planning it the right way ensures added value and avoids you in getting red tape from building authorities and planning permission.

1. Prepping the area

Start the home extension by ensuring that the site under extension is properly accessible and other liveable areas are well protected.

Set up alternate arrangements for bathroom or kitchen entry in case necessary.

2. Beginning the groundwork

If there are any unwanted structures, they’ll be demolished by the home extension builder or hire a demolishing expert in case you plan to do it yourself.

The areas will be cleared to make space for the storing of materials and other building materials.

Soakaways and gullies are installed for surface water management.

3. Laying the foundation

The foundation will be dug, and reinforcements will be installed.

Pipe work and drainage will be laid as necessary, and the concrete for the footing will be poured and leveled.

The base floor is prepared by laying hardcore, sand, damp-proof membrane, insulating and then filling it with concrete.

4. Starting the construction work

Construction process begins and walls start going up.

Lintels and other window sills are inserted as the work is carried on depending on the height of wall and type of cladding required.

For multi storey construction, upper floor joists are fitted.

5. Roofing

Proper trusses and other gable walls are installed that form the frame.

Vents, battens and felting are added. Tiling the roof is done post that.

Guttering, flashing and downpipes are also installed during the roofing process.

6. Fittings

After the roof has been laid, windows and doors are installed.

Connect with plumbing expert or your contractor for plumbing, electricity and other central heating needs.

The new space is reconfigured and floor insulation is done along with underfloor heating pipework (if required).

Concrete screed is poured that forms a subfloor.

7. Interiors

Internal insulation is up next, and the plasterboard will go up, while the walls will be skimmed, ready for decorating.

Now it’s the time to do the interiors such as fitting the cabinetry, laying the floor, other carpentry, integrating appliances (if any) and decorating the space.

What Building Regulation Do I Need for A Home Extension? (Updated 2023)

Planning Permissions Rules for Home Extension

When planning a home extension, it is important to obtain the necessary planning permissions before starting the project. In the UK, there are specific house extension rules and building regulations that must be followed to ensure that the extension is legal and safe.

Planning Permission and Permitted Development

Planning permission is a legal requirement for most home extensions. It is the process of obtaining permission from the local council before starting any building work.

This permission ensures that the proposed extension meets the necessary safety, health, and environmental standards.

Permitted development rights allow homeowners to carry out certain types of building work without requiring planning permission. However, these rights have certain limitations, including the size, location, and height of the extension.

To obtain planning permission, homeowners must apply an application to the local council. The application should include detailed plans of the proposed extension and information on how it will affect the surrounding area.

Common Reasons for Planning Permission Refusals

Planning permission refusals can be due to several reasons, such as the extension being too large or tall, not fitting in with the local area, or impacting on the privacy of neighbours.

Appeals Process If planning permission is refused

Homeowners can appeal the decision to the Planning Inspectorate. This process involves submitting further evidence and providing reasons why the proposed extension should be approved.

Failing to obtain the necessary planning permissions can result in legal issues, as well as costly fines and even demolition of the extension.

Therefore, it is essential to ensure that all the required permissions are obtained before starting any building work.

House Extension Rules for different types of Extensions

We’ve compiled various home extension rules for different type of house extensions. 

Home Extension Rules 2023 for Side Extensions

  • Side extension should sit to the side of the house (not front) and should not face a highway.
  • The height cannot exceed 4 m.
  • It can only be single storey. Multi-storey is not allowed.
  • The extension can only be 50% of the width of the existing house.
  • The eaves and ridges shall not be taller than the existing house.

Semi detached House Extension rules 2023

These semi detached house extension rules ensure that the extension is safe, doesn’t compromise the structural integrity of the property, and doesn’t have a negative impact on the surrounding area.

  • If you plan to build a single-storey rear extension, it can’t extend more than 4 meters from the existing rear wall of the house.
  • For double-storey extensions, the maximum extension is 3 meters. Additionally, if your house is located on designated land or in a conservation area, there may be further restrictions on the size and placement of the extension.
  • The maximum height allowed is 4 meters. If you plan to build a double-storey extension, the height of the extension can’t exceed the height of the existing house.
  • The construction materials for the extension should be in keeping with the original property. The design should be sympathetic to the character of the surrounding area.
  • If the extension overlooks neighbouring properties, you may need to include privacy measures, such as frosted glass or blinds.
  • You will need to obtain a party wall agreement that ensures that the construction doesn’t damage the shared wall.

Terraced House Extension Rules 2023

In most cases, terraced houses fall under permitted development rights, which means that certain extensions can be built without planning permission.

However, there are still some terraced house extension rules to keep in mind.

  • Single-storey rear extensions can usually be built without planning permission as long as they do not extend more than 3 metres from the original house for a terraced house, or 4 metres for a detached house, and do not exceed 4 metres in height.
  • For double-storey rear extensions, planning permission is required.
  • Side extensions are not allowed under permitted development rights, and any front extensions require planning permission.
  • If the proposed extension does not fall under permitted development rights, planning permission will be required.
  • Party wall agreement may be required, and the house extension must be required to meet the building regulations.

Front House Extension Rules 2023

Generally, planning permission is required for front extensions, so it’s better to check with your local council before starting any work.

Here’s a list of Front house extension rules to be followed.

  • Front extensions should be consistent with the character of the area, and they should not detract from the street scene.
  • The design and appearance of the front extension should be sympathetic to the existing property and should not harm the visual amenity of the area.
  • There are limits on how far a front extension can protrude beyond the building line, and these limits can vary depending on the location and size of the property.
  • The height of a front extension should be consistent with the existing property and the surrounding area.
  • A front extension should not create access or visibility problems for drivers, cyclists or pedestrians.
  • The materials used in the front extension should be of a similar quality and appearance to those used in the existing property, and they should not harm the visual amenity of the area.
  • Other regulations, such as building regulations and party wall agreements, may also need to be considered depending on the scope of the project.

Rear House Extension Rules

The size of a rear extension should not exceed 50% of the original house size or go beyond four meters in depth for a detached house, and three meters in depth for a semi-detached or terraced house. It should also be proportionate to the original house.

  • The maximum height of a single-story rear extension should not be more than four meters. If the extension has more than one storey, then the maximum height should not be more than three meters.
  • The materials used in the rear extension should match the original building as closely as possible. The design of the rear extension should also complement the style of the existing building.
  • The rear extension should not obstruct the access or egress of the neighbouring properties.
  • The rear extension should not be built within two meters of the boundary of the property unless the neighbours give written consent.
  • The drainage and sewage system of the property should be considered when designing the rear extension.

It is essential to ensure that you obtain the necessary planning permissions and building regulations before starting the construction of a rear extension.

Building Regulations UK for Home Extensions

Here are the key building regulations that you need to comply for your home extension project.

Home extension Rules and Regulations for Foundation

Foundations are the prime elements of any building that safely transmit the load of the building to the ground and provide a sound structural stability.

Depending on the requirements and load bearing capacity of soil, the foundations can be:

  • Shallow-Fill: Here the minimum thickness of load transfer to soil is provided.
  • Deep-Fill: Here the trench is filled completely.

Depending on the practicability and ground conditions, the fill varies from project to project.

There are several other factors that need to be considered while designing the building foundation. These are:

  • Type of Soil
  • Load-bearing capacity of the soil
  • Adjacent structures & Trees
  • Drains and sewers
  • Ground conditions
  • Landfill sites
  • Type of the new structure (extension)

Building Control Officers conduct three separate visits by the i.e. at the time of start, excavation and then, at the time of concreting.

Their word is final in all respects and may sometimes override your approved designs.

Home Extension Rules and Regulations for Ground Floors

The main function of a Ground floor is to bear the load and provide support to structure. Also, it must offer thermal insulation and pose resistance to ground moisture.

The floors in the UK are majorly constructed as the solid floor, suspended timber floor, and suspended concrete floor that uses pre-casted concrete planks.

The building regulations include:

  • The floors should be equipped with DPM (damp proof membrane) and should be thermally insulated.
  • The joists sizes, beam spans calculations must be done by a structural engineer and should be included in the plan submitted for approval.
  • For contaminated grounds such as those contaminated with gases such as radon, these areas need to be well ventilated. An additional gas membrane would be required to stop these harmful gases from entering the building and harming the structure.

Ground Level walls Rules for Home Extension

Depending upon the foundation, a substructure may be constructed below the ground level. The main walls (above the ground) or superstructure will be built on this.

The main objective of building a substructure is to provide adequate support to the superstructure.

This below-ground brick-and-mortar structure should resist frost and underground sulphates.

House Extension Rules for Walls

The main walls or the external walls of the home extension should be all-weather proof which means they should be able to resist whatever weather throws at them.

Additionally, the walls should add to the building’s structural integrity and minimize heat loss.

The strength of the cavity walls depends on the corrosion resistance ability of the wall ties that should be inserted at the proper spacing that will induce thermal bridging.

Internal walls can be stud partitions or load-bearing when structural integrity is the primary consideration.

Whatever the choice, the internal walls should comply with fire resistance and sound insulation regulations.

Additional strict measures may require in the case of multi-storeyed buildings.

Structural Openings Rules for Home Extension

After the newly constructed home extension has been made waterproof, a structural opening is usually made through the existing main/external walls.

This is done by removing the existing window or French door, ensuring that the load on the existing lintel stays the same. Normally, no extra support is needed.

But, for a wide opening, additional support shall be required. This is usually done by using steel beams.

The beams are installed as per the calculations done by the structural engineer and are mentioned in the drawings.

These structural components, such as timber or steel, need to be fireproof to give them an additional resistance of at least 30 minutes to fire breakout.

House Extension Rules for Upper floors

Apart from accommodating furniture, internal walls and occupants, floors play a vital role in providing rigidity to the walls and making the structure lateral resistant.

Your structural engineer or home extension builder in the UK will specify the type of floor, and ceiling joists requirements with correct spacings and spans in the layout plan.

Along with these, acoustics and fire resistance should also comply with building regulations.

House Extension Rules for Single Storey 2023

According to revised regulations and rules for single storey house extension, these extensions must not extend more than 4 m beyond the rear wall of the original house if it’s a detached house, or three metres for any other house.

With prior approval and not on the mentioned land, the limit for single-storey rear extensions increases to eight metres for a detached house, or six metres for any other house.

Prior approval application is necessary to inform the relevant Local Planning Authority of the proposed work. Additionally, the height of single-storey rear extensions must not exceed four metres.

House Extension Rules for More than one Storey 2023

Extensions exceeding one storey in height must not surpass the rear wall of the original property by more than 3 meters or be located within seven meters of any boundary opposite to the rear wall of the house.

The roof pitch should exactly match the existing house as closely as possible.

If an upper storey is built on an existing extension, the roof pitch should still match the original house. Upper-floor windows located in a ‘side elevation’ should be obscure-glazed and non-opening, unless the opening part is more than 1.7 metres above the floor.

Any side extension that is more than one storey high requires householder planning permission.

Home extension Rules for Roofs

Along with dimensions, spacings and spans of the roof, the UK Building Regulation also demands compliance to type/quality of timber used, and specifications of steel beams used for roof structures.

According to the regulations, the roof coverings such as slates, tiles or flat roof membranes should be weatherproof and appropriate for the roof pitch.

A breather membrane underlay is also desired to ensure correct levels of insulation and ventilation.

Proper flues must be designed to ensure the combustion gases escape safely.

House extension rules for Windows and Doors

The building regulations UK for windows and doors cover compliance to everything from ventilation, thermal efficiency, and fire safety to guard rails, glazing safety, security, and sound insulation.

Suitable guard rails are required for French windows or balconies.

Home Extension Building Regulations and Rules for Ventilation

The home extension should be well-ventilated to ensure proper health and to make the space airy.

While inserting/constructing a new wall, proper care should be taken that so that it should not impact the ventilation of the other rooms.

Adequate extract ventilation should be provided for bathrooms, kitchens, utility rooms or toilets to reduce congestion and condensation levels and remove smells.
