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.

What does the build quotation include?
The quotation allows for everything that is required to construct the ‘shell and core’ of the extension.

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.

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.

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.
