Confirm that it is worth extending your home

Before you start preparing to have your home extended, it is worth taking the time to consider whether it is definitely a project you are willing and able to take on. While a home extension is a brilliant way to increase space in your home without moving and will increase the value of your property, there are a few drawbacks. A home extension project will be expensive, time-consuming and potentially stressful. However, you can minimise these downsides of having a home extension done when you entrust the experienced professionals at JVH Building Services with helping you design and carry out the project. You can get in touch with our team to find out more about our services and how we can make your vision a reality.

It is important to decide what your greater priority is: adapting your property to suit the lifestyle of you and your family or increasing its value and making it more appealing to buyers. If the former is more important to you, you may want to extend the areas that you use the most and feel you would like to be bigger. Meanwhile, if the latter is a greater priority, you may wish to extend your space in a way that will appeal to your target buyers. You should also consider that there may be a ceiling price that your property will sell for, depending on the type of property and its location. By discussing with a local estate agent, you will be able to get a better idea of how much value an extension may add to your home.

Apply for all necessary permission

You will not need planning permission to build your extension if the work falls under permitted development. However, if it does not, you must apply for permission. Therefore, it is essential to inform yourself on what falls under permitted development so that you can accurately assess whether your planned extension will or not. Some stipulations of permitted development include that an extension cannot occupy more than half of the land surrounding the existing property and that the extension must be built with similar materials to the existing structure.

As well as informing yourself of these rules, you should also always discuss your plans with your local authority planning department to confirm whether or not they fall under permitted development. Checking will help you avoid a hefty fine and is especially important if you live in a conservation area or your house is listed, as rules surrounding development may vary.

Check building regulations

In order for your extension project to comply with building regulations, you must ensure that all tradespeople working on it are fully certified by official governing bodies. Should your extension not meet these regulations, you run the risk of having to take it down at your own expense. This is why it’s imperative to select fully qualified, trustworthy professionals to manage and carry out your extension project. Our team members at JVH Building Services are highly trained, fully certified and have many years of experience in carrying out house extensions in Brentwood and the surrounding areas.

Update your insurance

You will need to inform your buildings insurance company of your extension project before commencing with the build. This is to ensure that in the unlikely event of your home being destroyed by a fire or flood, the re-building cost compensation reflects the full value of your home, including the extension. You may be required to increase your insurance payments, but it will be worth it to protect yourself and your assets against the possibility of an incident and provide yourself with peace of mind.

Talk to your neighbours

We recommend informing any immediate neighbours of your plans to extend your home well in advance. By opening up this discussion, you will be able to address any concerns that they may have and keep relations friendly, as building work is a common source of neighbourly tension. If you have applied for planning permission, the local authority will get in touch with your neighbours about your planned project, and by discussing things with them before this happens, they are less likely to express any objections to the authority.

Moreover, your extension plans may require you to obtain a written party wall agreement from your neighbours. This will be far easier to do if you keep relations with the affected neighbours friendly and take the time to fully inform them of your plans. Reasons that you may require a party wall agreement include the following:

  • You live in a terraced or semi-detached home
  • You have a garden wall built over a property boundary
  • Your plans require excavation work

Home Extension FAQs

Here we will answer some common questions people have when it comes to building an extension:

Does Building An Extension Add Value?

Building an extension is an excellent way to invest in your property since square footage is commonly used to determine the value of a property. The number of bedrooms and bathrooms is also typically an influencing factor, so including one of these in your extension can also drive up the value of your home. It is estimated that the value of an average three-bedroom home could be increased by up to 23% with an extension.

How Much Will It Cost To Build An Extension?

Homebuilding & Renovating estimates that the average home extension in 2022 will cost somewhere between £1,350 and £2,250 per square metre. Factors that can affect the cost of an extension include how many storeys you plan on extending, the quality of the build, and the room(s) that you are extending.

How Close To My Boundary Can I Build An Extension?

How close to your property boundary you are able to build your extension will depend on several factors. We recommend checking out this article by Fifi McGee for an extensive guide on building close to or on your property boundary.

How Long Does It Take To Build An Extension?

The length of time an extension will take to build naturally depends on the size of the extension, including square footage and whether it is a double or single-story addition. We recommend that clients expect the entire process, from initial planning to completion, of arranging and building an extension to take around a year. This time will include applying for and waiting for the approval of planning permission, the design and planning process, and actual construction. The latter can take anywhere between three and six months, depending on the size of the extension.

Can You Build An Extension On A Leasehold Property?

Yes, you can build an extension on a leasehold property, though you should always seek and obtain permission from your freeholder to do so. We recommend doing this as soon as possible, i.e. before applying for planning permission. Your freeholder is unlikely to object as they too will benefit from the addition of an extension to the property but should be informed of your wishes regardless, in case there is an important reason why the property cannot be extended or they have any stipulations about the build.

Can You Build An Extension Over A Drain?

If a drain on your property serves only your property, it is a private drain, and you can build over it. However, if a drain serves even one property other than your own, it is a public drain, and you will need to apply for permission from your local drainage authority before building over it.

Can You Build An Extension On A Shared Ownership House?

If you are thinking of building an extension on your shared ownership home, you should apply for permission from the relevant housing association before commencing with designing and planning the extension.
