A house or kitchen extension is an investment in your home, so we know you will have a few questions before you get started.
A standard house extension takes between 7 to 9 weeks for the initial build. And a further 5-7 weeks for installation of kitchen and other facilities. Overall, there size of the building and the scope of the extension are the major factors on how long the house extension will take.
Our lead times are currently at 3-4 weeks, assuming you have the architectural plans, structural calculations, and party wall notices ready. House Extension London have teams all over London and the home counties. Wherever you are based, we can get your house or kitchen extension started in as little as two weeks.

House extension is one of the fastest and most effective way to add value to your house. An expertly constructed and finished house or kitchen extension can add up to 25% value to your house. It’s a fantastic amount of value added to your house instead of spending this on stamp duty when moving home. At House Extension London, we believe you should prefer moving up instead of moving out.
Our process of House extension in Home starts with a site survey where our surveyor will visit your property and guide you on what is possible. All this will be free of charge as it’s a no-obligation quotation. After the site visit, you will be provided with a rough quote until we have the structural calculations ready. Once you are happy with the quote, we will draw a contract to be signed and give you a start date. House Extension London tries to cater for all our customers needs and we are proud to be one of London’s best extension builders.
We review our prices every quarter to take into consideration price increases of materials and inflation too. Our quotations are therefore value for up to four months. In this time period, you can alter your quote to suit your needs if needed. We will work alongside you to alter any design you want until you are fully satisfied with it.
A recent article from Uswitch (https://www.uswitch.com/loans/guides/home-improvements-that-can-add-value-to-your-home/) states that a Kitchen extension will add up to £3k per m2. We suggest to speak to your local agent in Home to get an idea of the estimated increase in value of your extension.
Permitted development guidelines for the house extension size can vary based on the type of property you are extending. As a general estimate is that 3m is allowed for a terraced and semi-detached properties. Detached properties can get up to 4m without planning permission.
You will need planning permission for an extension when the design and size of the extension exceeds the provisions of permitted development. If you live in a flat or conservation area you will need to apply for planning permission regardless of the design and size of the extension.
Once the planning application has been submitted to the local authority, it can take up to 8 weeks. It takes between 4 to 8 weeks for an architect to prepare and submit the plans. Ideally, we suggest to give at least 3 months in advance for the construction company to start the process.
By adding a house extension, the demand for current hot water and heating systems will increase. You might need to change to a new boiler that has a bigger output. Many homes tend to install a hot water cylinder when extending their property to the rear.
Your neighbours cannot stop you from constructing up to, or even on, the boundary between your properties, even if it requires access onto their land. This issue is not covered by planning or building control. If you are undertaking a house extension that involves digging or building foundations within 3m of the boundary, party wall or party wall structure, or digging foundations within 6m of a boundary, this sort of work will require you to comply with the party wall act. You will need a surveyor to act on your behalf. Such an act does not apply in Scotland.
If your house extension will be built over or near a seer, you have to contact your local water board before work commences. In many cases, your architect will have to draw plans on how you intend to change the pipework, and these will be submitted to the water board for approval. It can take up to 3-4 weeks to get this approved and we strongly suggest not to start any work before obtaining a letter of approval.
Yes, it is normal to live on the site throughout the house extension, however there will be dust and mess and it can slow down the progress as the builders will try to work around your life. If you are not prepared to live with the disruption, then you should surely look for temporary accommodation especially during the dusty stage.
Yes, before you commence your construction project, you will need to submit either a building notice or a full planning application to building control. A building notice will allow you to start the work quickly but there will be lack of protection that a building control has signed off on the construction work. In this case, you will be liable to correct any work that faults to meet building regulations standard upon inspection.
Regardless of whether planning permission is required or not, any sort, any construction project must comply with the building regulations. You need to make sure that whoever undertakes the work can self-certify the work, for example, FENSA accredited window fitters, Gas Safe engineers, NIXEIC registered electricians and so on. If these requirements are not met, you could be served notice to take the extension down and will have trouble selling your home without relevant building regulations certificates.
Before starting your house and kitchen extension, its vital you give as much information as possible on what you want from the house extension, your timings, how and when you intend to pay them and what penalties will be in place if deadlines are missed. The architect will send you a detailed plan and a contract to sign.
If your house extension requires any structural changes to your home, you may need a structural engineer. A structural engineer can provide the technical drawings and calculations which can be used to get building regulation approval. This will also be used by the construction company during the house extension work.
I have had a site survey how long will it take to receive my quotation?
Once a London house extension project manager has visited your property and carried out a survey it will take no longer than 7 working days for you to receive a comprehensive quotation, sometimes we can quote on the same day! If you have not received your quotation within the 7 working day period please check your junk folder, as sometimes quotations end up there by mistake. If you would like to discuss your quotation or add extra things on to your design, then please don’t hesitate to speak with one of our friendly advisors.
What does the build quotation include?
The quotation allows for everything that is required to construct the ‘shell and core’ of the extension. This means we’ll get your home to a watertight shell and install the windows, external doors, lights and plumbing – everything to get the final sign off from Building Control. We can help with the final decoration, kitchen fitting, bathroom fitting and floor fitting should you wish.
How much does it cost?
The potential cost of a kitchen extension can be calculated accurately when detailed designs and the full specification are established beforehand, along with a site survey to identify any potential issues before the build starts. The size and scope of the kitchen extension will dictate the amount of work involved, along with the cost of materials, and this is how the build quote is reached. At London House Extension, we take all the information we have about your proposed works, carry out a site survey and produce a detailed quote for your specific requirements. Our prices are fixed, although if you make changes to the plan during the build, there may be additional costs.
What factors affect your planning options?
House type, flats, maisonettes, and listed buildings always require a full planning application Location. Homes in conservation areas can have their permitted development rights limited, while rules differ between England, Scotland, and Wales Project size: only projects that follow height and volume requirements will qualify for permitted development rights Project type: not all extension types fall under permitted development, notable exceptions are wraparounds and basement retrofits Design. the permitted development route tends to be best suited to conservative designs that are in keeping with the existing house aesthetics

If we decide to use House Extension London architectural service, how long does it take to get plans drawn up?
Our process of building extensions in London and all surrounding London area begins with a site survey where a House Extension London surveyor will visit your home, completely free of charge. Once the visit has taken place, you will be provided with a quote – this quote isn’t set in stone, House Extension London can change the quote as many times as needed before you commit. Once the contract is signed (with the set time scale), the plans can begin to be drawn up. With all the above taken into consideration, it takes us, on average, between 4 – 5 weeks from signing the contract to get our clients to agree on a set of plans, but of course we have had faster approvals if a client is in a particular hurry. House Extension London aims to cater to every client’s individual needs, and we pride ourselves on being the best extension builder in London.
What is the difference between permitted development rights and planning permissions for extensions?
With Planning permission, you are asking the council if your proposed extension is acceptable. It is open to rejection by them and/or your neighbours and will have to follow the local development plan. With permitted development you are asking the council to simply confirm that your plan fits within the permitted development criteria. The council will issue you a Lawful Development Letter if they agree. Technically you are not required to have the Lawful Development letter in place before the work starts and in fact there is no law stating you must have it. This allows clients who request it, to start the work without waiting for the Lawful Development Letter, thus saving time.
What documentation do I need for a house extension?
Here at House Extension London, we can deal with most paperwork required. This includes Planning Permission. Building notice, Architectural Plans, Structural Drawings, Build over agreement.

Our drawings include enough detail to satisfy Building Control, if they have any questions throughout the build, we will support you and answer any questions or quires you may have even if you chose to build with another company
Can I just commit to the design or build phase only?
Yes, absolutely. We offer a two-stage process, so you can commit to the Design phase and leave the Build out to tender or complete Design with other company and get only Build Phase from us.
How much disruption should I expect throughout the build phase of an extension?
There is no doubt that building work can at times be disruptive and slightly stressful, after all we are completely altering your home! However, there are certain tips and measures that can be taken to ease this process. If budget allows, you may decide the best way to avoid the disruption is to move out throughout the construction phase. However, we know at times this can be unrealistic and costly. Other steps are to build temporary kitchens to enable you to still cook and clean, or to build stud partitions to block out the dust from the rest of your home. Always remember to pack away any valuables or anything that could potentially be damaged as materials and equipment will be making their way through your home. It’s important to remember all the disruption will be worthwhile when you have your brand new
