How to extend a house a guide to planning your extension

"These changes will help transform boarded up, unused buildings safely into high quality homes at the heart of their communities. If you are within 2 metres from the boundary, the maximum height of your extension’s eaves should be 3 metres. The exterior of the extension must use similar-looking materials to those of the property.

Eaves and ridge heights on extension are no higher than the host property. The best way to compare mortgage costs and find the right deal for you is to speak to a good broker. While an extension should add value to your house, it's not automatically the case.

Can I extend the front of my house?

When setting out floor levels for an extension, it is important to work backwards from the finished floor level in the existing property to ensure they will be identical once they’re linked. It's always best to pick a designer with a style or track record of projects that match up to what you're trying to achieve. Ideally, a local firm is a better choice than one that's distant, since they will be more familiar with the local vernacular and the local council's foibles. For a major project such as an extension, it makes sense to get your design approved with the former before you start work, otherwise you could run into trouble if your project doesn’t comply with the regulations. A solar panel can be added to a roof under permissive development, provided that it does not extend beyond 200mm from the roof or wall and that the panel’s highest point does not exceed the roof’s highest part.

For detached houses, single-storey rear extensions can extend up to 4m and for other houses up to 3m. A party wall is a wall, boundary, or outbuilding that you share with another household. These are common between terraced and semi-detached houses, but can also affect detached properties if you share a garden wall or invisible boundary line. From designing your home, to permitted development rights and building regulations, you'll find everything you need to know about extending a house right here, including how to add value to your home via an extension. The larger house extension plan, which was abolished in 2020, enabled homeowners to erect single-story back extensions that were larger than permitted development rights allowed. Its allowances were added to approved development rights once it was disbanded.

Basement conversions

One of the main considerations to determine how far you can extend is what kind of property you own. 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 your extension falls under permitted development rights, you can bypass the traditional planning process and the subjective decisions that go along with it. However, this doesn’t mean you can skip your local planning authority altogether. Larger extensions can be required to seek our prior approval first and even small projects should at least secure a lawful development certificate.

Most obviously, this relates to structural stability – including foundations, window and door openings, lintels, beams and roof structures. Therefore, your design will normally need to incorporate a structural engineer’s calculations, submitted together with drawings as part of your building regulations application. Organising the access to your extension is an important early step to consider when planning a house extension because it could limit your design options. Having materials craned over a house is possible, but it's extremely expensive and you need to get the agreement of the council to close the road temporarily. To start with, you have to know what you want and it has to be simple in its style and planning requirements.

Plus, if you’re attaching an extension to an existing one which exceeds those limitations, Permitted Development doesn’t apply. The rules for permitted development depend on how many storeys your extension will have. The new planning law will come into effect in September as part of a package of measures designed to shake up planning permission and revitalise town centres. Getting planning permission when looking to expand your family home can be a minefield of negotiating neighbours objections. However, due to a new planning law this could become a thing of the past. If your extension affects a neighbour’s property, this is known as a party wall matter and it's important you know the rules around this before work begins.

Joe Warner, director of architecture at BDN Ltd, recommends investigating the materials used, too, by speaking to a structural engineer. For example, alterations to timber-framed properties can pose a challenge. Some properties may also be subject to restricted covenants — third-party rights which are registered against the title of the property. Prime Minister Boris Johnson recently made a promise to reform planning rules and said he hoped his programme of "build, build, build" would help the country recover from the effects of the coronavirus pandemic. Libraries, pubs and village shops are among the buildings not covered by the new rules, due to recognition that they form part of the local fabric of areas.

You can use an online plan drawing service, or to use a building firm that offers a ‘design and build’ service. There’s also the Party Wall Act to consider – even if your project falls under Permitted Development. If your plans will involve building against or excavating within 3-6m of a party wall you share with a neighbour, you might have to give them two months notice. A party wall is one that forms the structure of both your properties, but could also be a garden wall that divides your plots. By building an extension on a house, even by a few metres, you can truly make it your own and get the space you have working harder to support your lifestyle. We expect so much more from our properties now, preferring to cook and eat together, entertain, work and exercise at home.

This is to make sure that there are no other constraints to think about. 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.

Should the worst happen, the builders who did the work will need to return to put right what has gone wrong. All alterations tolisted buildings, including internal ones, require consent and it is a criminal offence to alter a listed building without it.

If you want to add a storey to an existing single-storey extension, this won’t be possible under Permitted Development Rights if the existing addition extends beyond the rear wall by more than 3m.

The same is true if there’s a substantial distance between the house and the road, or if there’s a tract of land owned by someone else between your boundary and the road. This gives your neighbours 21 days to object, giving valid reasons. After that, your Local Planning Authority has another 21 days to grant approval and you pay a fee for a Lawful Development Certificate – proof that your Permitted Development project is legal. If you’re attaching this to an existing extension, these measurements must incorporate both the old and new additions.
