Rules for house extensions: All You Need To Know About House Extensions in 2023

All You Need To Know About House Extensions in 2023

If you are planning on building an extension, then you need to know the house extension rules 2023 are for building. However, don’t let this detract you from choosing to build an extension. You just need to be aware of the house extension rules in place, so you can build the dream extension you have always wanted.

We are going to summarise the key factors you need to think about when it comes to building an extension.

House Extension Rules 2023

When considering a home improvement project, it is important to choose an experienced architect to guide you through the house extension rules 2023 in order to provide you with the optimised layout and external design for your property, not just to increase space, but to implement innovative designs that can physically improve your day-to-day.

Whilst there are many house extension rules to consider in 2023, they are not all that complex, but when combined together with areas of conservation, heritage, or other designated land such as metropolitan greenbelt, they can be a tricky scene to navigate. Welcome to Extension Architectures guide to House Extension Rules 2023.

One of the main considerations to determine how far you can extend is what kind of property you own. For example, terraced or semi-detached house extension rules are considerably different from those of a detached property, and this generally will relate to the impacts any extension will have on your adjoining neighbours. Another important factor of house extension rules 2023 is whether you intend to apply for planning permission or enlarge your home using your permitted development rights. These are nationally set guidelines on what you can and cannot do without planning consent from your local council, and can be tricky to navigate if you are not accustomed to the permitted development rules UK.

If you need help understanding how far you can extend or if you need planning permission for your house extension 2023, our specialist advisors are here to help!


Single-Storey Extension Rules

  • You can only cover half the area of land that is around the original house with an extension or any other type of build. This can also include a shed or outbuilding.
  • The extension cannot be forward of the side elevation or side elevation fronting a highway. This means that if you want to build your extension out toward the main road, this would require planning permission.
  • The materials used must be in line with the property’s current look, the obvious exception is a conservatory.
  • If you have a property on, what is known as, designated land then you won’t be allowed exterior cladding.
  • For a single-storey rear extension, you cannot go beyond the back wall of the original property by more than four metres.
  • The extension cannot exceed four metres in height.

Two-Storey Extension Rules


  • If your house is more than one storey, then if you extend, you cannot go past the back wall of the house by over three metres.
  • The maximum height of the extension’s eaves needs to be three metres if you are within two metres of the boundary.
  • The ridge and eaves height cannot be taller than the existing property.
  • The extension needs to be a minimum of seven metres away from the rear boundaries.
  • The roof pitch needs to match or be as close to the existing property as possible.
  • You need planning permission for any raised platforms, verandas, or balconies.
  • The upper-floor windows in the roof slope or wall on the side elevation need to be obscure-glazed and can’t be opened.
  • On any designated land, a two-storey extension is not covered by permitted development rights.
  • The exterior of the extension must use similar-looking materials to those of the property.

Side extension rules

  • A single-storey side extension must not exceed four metres in height and cannot have a width of more than half of the original property.
  • Side extensions are not permitted on designated land.

Rear extension rules

  • A single-storey extension to the rear of a property will not go beyond the rear wall of the original property by no more than four metres.
  • A single-storey extension to the rear can be no more than four metres.

Terraced & Semi Detached House Extension Rules 2023

Permitted Development / Prior Approval

  • Under permitted development for a terrace or semi-detached home, you have the rights to extend by up to 3m without the need for planning permission!
  • For this you will need to apply for a lawful development certificate, which can be done either before or after construction, however we recommend the prior as it is always good to be sure that what you are building falls under the category. This will be necessary if you intend to sell the property at a later date, within 4 years of the building work completing.
  • There are specific rules to follow for permitted development projects, which is why it is always important to consult an experienced architect to ensure your projects success.

Householder/Full Planning Permission

  • If your property is within a conservation area, or if you are looking for a more unique extension with materials that differ from the original building, you will need to apply for planning permission for your extension.
  • Terraced & Semi-detached house extension rules under a householder application differ from council to council, but as a general rule of thumb you should not infringe upon the 45 degree rules – a line drawn at a 45 degree angle from your neighbours closest inhabitable space, i.e. a kitchen, living space or bedroom, as to not infringe upon their outlook and access to light.

Detached House Extension Rules 2023

Permitted Development / Prior Approval

  • Under permitted development for a detached house, you can extend up to 4m under permitted development, and up to 8m under the larger home extensions scheme / prior approval.
  • As above, many other factors need to be considered, therefore it is always good to speak with an experienced architect to ensure your proposal meets all of the house extension rules 2023.

Householder/Full Planning Permission

  • As above, if you live in a conservation area or other designated land, if your building is listed by heritage England, or if you are looking for a more unique extension, you will need to apply for planning permission from your local planning authority.
  • For a detached house, house extension rules 2023 are much more lenient, especially if your property sits on a large plot with generous space between neighbouring properties.
  • However, it is always important to check with an experienced architect, who will know exactly where to find the relevant council guidance to ensure that your project does not exceed the recommended allowances for detached house extension rules!

Firstly, it is important to note that any extension to a semi-detached property must comply with the Building Regulations. These regulations are in place to ensure that any structural changes made to a property are safe and comply with UK building standards.

The first thing to consider when extending a semi-detached house is the party wall. The party wall is the wall that separates your property from your neighbour’s property. If you plan on building an extension that will affect the party wall, then you will need to follow the Party Wall Act 1996. This act is in place to ensure that any work you carry out on the party wall is done safely and with the agreement of your neighbour.

When it comes to the size of your extension, there are specific rules that apply to semi-detached properties. In general, you are allowed to extend a semi-detached house to the side by up to half the width of the original house, and to the rear by up to three meters, or four meters if you have obtained prior approval from your local authority. However, it is important to note that these rules may vary depending on the location of your property, so it is always best to check with your local planning authority before beginning any work.

Another important factor to consider when extending a semi-detached property is the impact it may have on your neighbour’s property. It is important to ensure that your extension does not cause any damage or loss of amenity to your neighbour’s property. This could include blocking their view, causing damage to their property, or reducing their privacy.

In addition, it is important to consider the materials you use when building your extension. If your semi-detached property is located in a conservation area or is a listed building, then you may need to use specific materials that are in keeping with the character of the surrounding area. This is to ensure that any changes made to the property do not detract from the historic or architectural significance of the area.

Finally, it is important to consider the impact that your extension may have on the value of your property. While an extension can increase the value of your home, it is important to ensure that any changes you make are in keeping with the surrounding area and do not negatively impact the value of your neighbour’s property.

Extending a semi-detached property in the UK requires careful consideration and planning. It is important to ensure that any work you carry out complies with the Building Regulations, the Party Wall Act, and any local planning regulations. By following these rules and regulations, you can ensure that your extension is safe, in keeping with the character of the surrounding area, and adds value to your property.

Permitted Development Rules 2023 – How far can you extend without planning permission UK

These are what are known as permitted development allowances. They only apply to houses. Flats, other buildings and maisonettes are not included. It is important to check with a Local Planning Authority to see if the permitted development rights will apply to your extension. This is to make sure that there are no other constraints to think about.

You may be wondering how far you can extend without planning permission 2023, and this will vary depending on the type of house you own. Permitted development changes came into place in 2020 as a result of the ongoing pandemic and many homeowners needing additional space to go about their daily routine. This would also boost the UK economy, by giving work to contractors and service companies throughout an otherwise challenging period of time.

The changes implemented the larger home extension scheme, otherwise known as prior approval. This is a 28 day application to determine, via your neighbours non-objection, how far can you extend without planning permission. For example, for a terrace or semi-detached home, you can extend up to 6m as opposed to the original 3m, and for a detached property you can extend up to 8m as opposed to the original 4m.

With this in mind, however, you must be careful as many factors contribute to your extension falling under PD, such as the height, ground level, raised platforms, the original, as-built property footprint and boundary wall placement.

House extension without planning permission: what are the rules?

In case you’ve been wondering, yes, it’s possible to build a house extension without planning permission — and it’s all thanks to permitted development.

Nevertheless, there are rules and criteria that the extension must meet to qualify for permitted development. It is vital that you understand these rules and criteria before embarking on your project. This way, you can avoid getting into trouble with the law.

These rules control almost every aspect of your proposed house extension, from how high the extension can be to what to do if there’s a highway nearby.

In this article, we’ll cover:

  • Building a house extension without planning permission
  • Benefits of extending without permission
  • Basic conditions for extending without permissions
  • Indemnity insurance
  • The larger home extension scheme

Plus a host of other tips and tricks! If you’re about ready to add that extension, you can get your Resi quote here.

Benefits of extending without planning permission

  • Permitted development is not subjective. You already have a comprehensive idea of what is accepted and so can design within that boundary
  • With reduced planning risks, you’re less likely to be subjected to hidden costs, such as reapplying for permission
  • Permitted development rights are a fantastic option for anyone living in areas known for high planning refusals, as they operate outside of the council’s own (sometimes harsh) guidelines
  • With the guidelines already in place, you may find permitted development rights help hone in your vision and give your designs a starting point

Basic conditions for extending without a planning permission

There are three primary conditions for extending your house without permission.

Have you or any previous owners extended the house since 1948?

You cannot extend a house without planning permission if it has been extended before, either by you or its previous owners. This rule covers extensions made since the 1st of July 1948.

Is your house listed or on “designated land” (conservation area)?

Listed homes and homes on designated lands (conservation areas, areas of outstanding natural beauty) have either limited or revoked permitted development rights. If your home falls under this category, we definitely recommend getting expert guidance when planning your extension.

Is your property a house or flat?

Only houses are covered by permitted development. Other property types like flats and maisonettes will require you to apply for full planning permission. Also, note that if your house has been converted in the past, it may not be eligible for permitted development rights.

You can discuss your project with a Resi expert to certify its compliance.

Larger home extension scheme

Before it was dissolved in 2020, the larger home extension scheme allowed homeowners to build single storey rear extensions that were larger than permitted development rights allowed. After it was dissolved, its allowances were added to permitted development rights. This meant that homeowners could still build larger extensions, but the way they would go about it now would be slightly different from when the larger home extension scheme existed.

Now, homeowners wishing to build larger extensions can simply apply for prior approval. With prior approval, you can extend a detached home as far as 8m for detached houses and 6m for other types of houses.

Permitted Development Rules for each extension type and renovations

The rules set out in the town and country planning (General Permitted Development Orders) 1995 detail all the changes you can and can not make without planning permission

Here are some of them:

For most extensions

  • The extension cannot use more than half of the land surrounding the original building
  • An extension cannot be taller than the tallest part of the building itself, neither can its eaves exceed the height of the existing eaves
  • You can’t have a forward or side extension on a building that’s too close to the highway
  • The height of the extension’s eaves can not exceed 3m once the extension comes within 2m of the boundary
  • The extension cannot include verandas, a microwave antenna, a chimney, or any alteration to the roof of the existing house
  • The materials used for the extension must be similar to the materials used for the exterior of the actual house

Rules for attached vs detached properties

  • Attached properties cannot be extended beyond the rear wall of the original home by more than 3m
  • You cannot extend a detached property past the rear wall of the original home by more than 4m
  • It must not extend past the rear wall by 4m for a detached house and 3m for every other kind of house
  • It must not exceed 4 m in height

For two storey extensions

  • The extension’s roof pitch must match that of the original house
  • First-floor windows of side elevations should be obscure glazed, and non-opening. The only exception to this rule is if the open window is at least 1.7m from the floor

For front extensions

Permitted development allows you to extend the front of your house provided your front extension:

  • Is a single storey
  • Doesn’t front into the road
  • Isn’t more than 3m out from the original house
  • Isn’t more than half the width of the original house

For porch extensions

You can build your porch without planning permission provided:

  • The porch isn’t higher than 3m
  • It’s at most 2m close to any boundary next to a highway
  • The external ground area isn’t more than 3m2

For rear extensions

  • Single storey rear extensions can be extended as far as 4m for detached houses and 3m for other houses. This can increase to 8m and 6m, respectively, with prior approval
  • Double storey rear extensions can go as far as 3m from the original house as long as it’s more than 7m away from the rear wall

For side extensions

  • It can only be one storey
  • Must not be higher than 4m

For basement conversions

You can convert your basement without seeking permission as long as

  • It’s not a separate unit
  • You’re not excavating to form a new basement
  • The usage is not significantly changed
  • The external appearance isn’t altered by the addition of a lightwell

To replace a window

You don’t need planning permission to replace your window as long as the new windows are similar to the ones being replaced.

To knock down internal walls

You probably won’t need planning permission to knock down internal walls as long as your house isn’t listed or in a conservation area.

For a rooflight

For permitted development to cover roof light installation:

  • The rooflight must not project past 15cm from the roof’s slope
  • It must not extend forward on an elevation fronting a highway
  • The property must not be located in a conservation area or an area of outstanding natural beauty
  • It must be non-opening or more than 1.7 meters above floor level if placed on a side elevation

For loft conversions

  • Cubic content cannot surpass 40m3
  • Dormer windows must not sit higher than the highest part of the existing roof
  • Dormer windows must not extend forward of the roof plane on the principal elevation

For garage conversions

Most garage conversions fall under permitted development as long as the work is internal and no enlargement is involved. The only exception to this rule is a detached garage. However, if your garage is built after the house, it’s worth checking in with your local authority to ensure that your home’s permitted development allocation has not been used up.

For conservatory extensions

Conservatory extensions have the same permitted development criteria as house extensions. They must not be higher than the main house and must not occupy more than half of the surrounding land.

For shed/garden room extensions

Sheds and garden rooms generally qualify as extensions under planning development rights. To build a shed or outbuilding without permission:

  • The outbuilding must not sit forward of the principal elevation
  • It must be only one storey with a maximum eaves height of 2. 5m
  • They must not be used or residential accommodation, for example, bedrooms or annexe

For a new fence or wall

You can erect, construct and maintain your fence or wall under permitted development rights if:

  • Its height doesn’t exceed 1m when adjacent to a highway
  • Its height does not exceed 2m for any other fence or wall
  • The property isn’t a listed building

For a swimming pool

Permitted development lets you build a swimming pool in your garden as long as it doesn’t take up more than half of the garden curtilage.

For solar panels

You can add a solar panel under permitted development provided it does not protrude more than 200mm past the plane of roof or wall, and the highest part of the panel does not surpass the highest part of the roof.

You can book a free consultation to discuss your project with a Resi expert.

An example of a house extension that did not require planning permission

This house extension was created using a loft conversion, which came under the homeowner’s permitted development rights – meaning no planning permission was required! The classic main dormer extension added bags of new space onto the household and includes not only new double bedroom, but an ensuite too.

In designing this house extension, our team used skylights to bring in plenty of natural light, along with a juliet balcony for an extra connection to the outdoors. While other balconies require planning permission, juliet balconies are exempt.

On using Resi, the couple had this to say: “We immediately liked the functionality of the platform. It was brilliant to be able to upload our inspiration ideas. We could brainstorm, but keep everything in one place – no more pieces of lost paper!”

Could missing planning permission affect the ‘saleability’ of my home?

Missing planning permission may affect the saleability of your home. How? Selling your property without providing the necessary documents could put the new owner at risk, as they will be held accountable for any breach in the law during its construction.

Retrospective planning permission

Although it’s more common to gain planning approval before starting on a project, there are some cases where the project had already begun before approval was sought (it may be that you made these changes without realising that they required planning permission).

In such a situation, retrospective planning permission is required. Retrospective planning permission allows you to file for approval after starting the project.

You should be careful, though, because if your application is not approved, you will be required to return things to the way they were.

Hence it’s always more advisable to apply for planning permission before embarking on the project.

Indemnity insurance

This usually comes up when a seller cannot provide planning permission for the extensions or additions to the home at the point of sale. In cases like this, the buyer will be advised by their conveyance solicitor to get indemnity insurance.

Indemnity insurance protects the buyer from any legal issues that may arise concerning the building’s compliance, for example, building regulations and planning permission.

It’s worth mentioning that while indemnity insurance covers a legal defect with the property, it doesn’t cover repairs, replacements, or installations.

Resi offers an all-in-one solution platform to homeowners wishing to extend or renovate their homes. Our team of experts are equipped to handle everything from planning and permissions to financing solutions.

very useful for many citizens. The clarity was made by the Judicial Collegium for Civil Cases of the Supreme Court of the Russian Federation, when she studied the dispute between the owner of the cottage and municipal officials who did not agree to legitimize the extensions to the house that the hostess erected.

You can go to court with a request to legalize buildings if there is evidence that the owner has already tried to do it himself. / Sergey Mikheev

Today it is almost impossible to find a private house or cottage, the owners of which would not eventually decide to enlarge their house. The scale of construction depends both on the owner’s wallet and on the flight of his imagination. Therefore, in the summer months, shops and building materials markets are overflowing with those who have started building and those who continue this exciting process. After all, it is almost impossible to complete the expansion of your possessions.

Owners of houses, in order to increase their real estate, attach attics, verandas and all kinds of other buildings to housing.

Experts of “RG” explain the legal aspects of housing management in the heading “Legal consultation”

But only after the construction is completed, the owners of these objects may have difficulty recognizing the ownership of them. How to properly legalize such buildings, and when it will definitely fail, the Supreme Court explained in the case of the Bryansk owner of a country house.

Her story began with the fact that our heroine expanded her private house, first adding a shed to it, and later a veranda.

After the construction was completed, the citizen decided to legalize these buildings in court. In her lawsuit, it was said that her new objects are on her own site. Justifying her demands, the citizen explained that the erected real estate does not violate anyone’s rights and does not pose a threat to the life and health of citizens.

What was her surprise when, first, the first instance, and later the appeal was denied to the woman. The local courts referred to the fact that the extensions to the residential building are partially located on the land of a natural monument of regional significance. Accordingly, the erected structures “violate the rights of an indefinite circle of persons to a favorable environment.” So the first instance recorded in its decision and the appeal agreed with such a verdict.

But the owner of the veranda and the barn decided not to give up and went to challenge the decisions of the Bryansk courts further and higher – to the Supreme Court.

What was the surprise of the owner of the house and land when, first, the first instance, and later the appeal refused to legalize her extensions

There, the materials of the civil dispute were carefully studied and declared that their regional colleagues made the right decision. The Supreme Court emphasized that the territories where our heroine built a barn and a veranda have been a special regime zone for more than 20 years. On this land, new housing construction and completion “with the gradual vyhoschivanie housing and resettlement of residents in environmentally friendly areas” are prohibited. This is stated in the decision of the administration of the Bryansk region (dated April 25, 1994 years No. 31). Due to the presence of a special zone, the Supreme Court said, the plaintiff will not be able to legitimize the objects. The Supreme Court recognized the acts of lower instances as legal.

Lawyers who specialize in such civil disputes have some advice for owners who may be facing a similar problem. So what is the right way to do it?

The first and most important thing is that the site of a citizen, on which he decided to start construction, must be his own. Then you need to get a building permit and a town-planning plan, which will reflect all the restrictions on development. But this is the longest way. There is a simpler option – it was possible to build a barn and a veranda as outbuildings that are not real estate.

Of course, you can do what our heroine did – legalize objects through the courts. But it must be borne in mind that in most cases the courts do not satisfy claims for recognition of the right of ownership of an unauthorized building, if the developer did not take measures aimed at legalizing the object before the start of construction. That is, he turned to officials, but they refused or did not answer him.

According to the Town Planning Code, extensions to residential buildings may not be classified as capital construction projects. When building such extensions, such as a shed or garage, a building permit is not required. True, after the completion of work, one must not forget to make changes to the technical documentation.

There is another difficult moment when a permit for construction or reconstruction is refused due to the presence of water protection and “other sanitary protection zones”. The latter often refers to land near airports.

Courts usually refuse if the owner did not try to resolve the issue with officials before the start of construction. Compliance of construction parameters with the requirements of urban planning regulations. And the absence of violation of the rights and legitimate interests of others. As well as the safety of the erected object.

But we must remember that the court will almost certainly ask for evidence of the land owner’s attempts to obtain the necessary permits before starting construction work.

Do I need to register an addition to a house on my own land?

All about Real Estate

Mikhail Bondarev Author of the article

During operation, it may be necessary to make changes to the construction of a private house, to increase its area. Then an extension is being built, which allows you to add one or more rooms to the existing square meters. Do I need to register it and how is it done?


  • What is an extension to a house?
  • Do I need to register an extension to a house on my own land?
  • Procedure for registering an extension before construction starts
  • Registration of an extension if it has already been built to a private house under a dacha amnesty

What is an extension to a house?

Any constructive change to an existing building is its reconstruction (clause 14, article 1 of the Town Planning Code of the Russian Federation). An extension to a residential building can be either on either side, increasing its dimensions in length or width, or upwards when the number of storeys changes.

An extension is an addition to a house that is not indicated in the project. It happens:

  • capital – built on a foundation, occupies additional land area, has one or more common walls with an existing house;
  • non-permanent – non-residential premises that do not require a foundation (veranda, shed, porch, open terrace, etc.).

Depending on whether the extension is capital or not, the process of its registration is different. Any non-capital construction may not be documented, this will not entail the application of sanctions to the owner. It does not radically affect the design features of the house, does not infringe on the rights of neighbors, and does not pose a danger to the life and health of residents.

But the legislation is constantly changing and it is not known how difficult it will become to register such an extension later. Today it is a matter of calling a cadastral engineer who will certify the new parameters of the house. Then the documents are submitted for registration along with the title documents for the land and the house.

A slightly different procedure if the extension is capital. It can be used to carry out a registration complex of events even before the start of construction or to do it after.

Do I need to register an extension to a house on my own land?

An extension to a residential building must be documented because:

  • the total area of ​​the object changes. New parameters must be registered in case the house is subsequently sold, inherited, etc. It is important to arrange a new area in the case of shared ownership of a house, because the size of the shares will change;
  • during construction, all construction standards must be observed, including setbacks from neighboring sites. In case of violation, the extension may be assigned the status of a self-construction. When registering, it is assessed whether the interests of neighbors are affected by marking the new boundaries of the object on the site plan. To do this, the cadastral engineer draws up a new cadastral passport for the house.

As a general rule, before erecting an extension, it is necessary to notify the authorized body and obtain permission for its construction.

But until March 1, 2026, the registration of individual housing construction objects can be carried out without such a document, under a dacha amnesty.

Procedure for registering an extension before construction starts

During the construction of a residential building, all necessary standards must be observed, including obligatory setbacks from neighbors, roads, etc. Reconstruction, i.e. a change in parameters in connection with the construction of a capital outbuilding must also comply with these standards. In order not to be recognized as a self-construction, it is better to agree in advance with the authorized body and obtain permission. To do this, do the following:

Step 1. Prepare a project for the planned extension.

This can be done by yourself or by a qualified professional. When creating a project, it is necessary to take into account the features of the land and the house.

For an individual residential building with no more than three storeys (not higher than 20 meters from the ground), intended for a single family, it is not necessary to prepare a reconstruction project.

Step 2. Draw up a notice to the authorized body of the intention to reconstruct the house.

Fill out and send to the administration (urban planning department) a notification, where you indicate your personal data (name, address, passport details), cadastral number of the house, title documents for the land, information about planned changes, method of obtaining permission. All specified data must be supported by relevant documents.

According to paragraph 1.1 of Part 17 of Art. 51 GrK and part 5 of Art. 16 of Law No. 340-FZ dated 03.08.2018, currently, when reconstructing an individual housing construction facility, obtaining a permit is not required.

Step 3. Get a new technical plan for the renovated house.

After completion of construction work related to the reconstruction of a residential facility, it is necessary to conclude an agreement with a cadastral engineer to carry out work on the preparation of a new technical plan for the house.

Step 4. Prepare documents for registration.

The following must be submitted to the authorized body:

  • notification that the reconstruction is completed;
  • technical plan of the house as amended;
  • title documents for the land plot on which the house was built.

Step 5. Submit the documents to the authorized body (local administration).

All changes will be registered based on the application of the authorized body. The owner of the land and the house is obliged, within 30 days after the completion of the extension, to transfer the necessary documents to the administration in person, by mail, through the MFC or the State Services portal.

Documents are checked for compliance with legal requirements and sent to Rosreestr for registration. At the same time, a notification is sent to the owner.

At the end of the registration process, the owner of the reconstructed house receives an extract from the USRN with new data.

Registration of an extension, if it has already been built to a private house under a dacha amnesty

Until March 1, 2026, citizens involved in the construction or reconstruction of an individual housing construction facility are exempt from obtaining an appropriate permit.

If the house is on the plot of individual housing construction or private household plot, then for the reconstruction already done, you need to go to court, because you had to send a notification earlier. If the site is a garden / summer cottage, then a technical plan is enough for the reconstruction.

If the extension has already been erected, the procedure for its registration is as follows:

  1. An agreement is concluded with a cadastral engineer for the execution of a new technical passport.
