How much will your house extension in Sittingbourne cost?

One of the main questions you are likely asking is, how much does a house extension cost? This depends on the size and type you opt for. Once you have decided on the most suitable extension for your Sittingbourne home, we can send one of our house extension specialists to your property to take a look at the work that will be required. They will then calculate the materials required and labour costs before providing you with a detailed quote for the total cost of the job. You can expect our team to contact you within 72 hours of visiting your property to provide your quote. For larger or more complex projects, we will keep you updated on the timeframe for your quote.

What is the house extension process in Sittingbourne?

We follow the same process on every project so that your extension goes to plan, and you can begin to make the most of the new living space at your Sittingbourne property:

Initial quote

Once you have decided on the most suitable type of extension for your home, we visit your property to assess the work that is required. We will then contact you within 72 hours to provide a quote, or if you have a larger project we will keep you informed whilst preparing your quote. We will review the contract with you to make sure that you are happy to proceed with the construction process.

Construction begins

Once the cost of the job is agreed, we will arrive at your property at a suitable time to begin the construction process. As the project progresses and your new living space starts to take shape, you can keep track of things via our online Gantt software or through regular updates from our team. Our senior project manager will carry out regular visits to guarantee that everything is going according to plan.

Quality check

Once we have completed construction and fitting, our team will go through numerous checks to ensure that your new extension is structurally sound and all new appliances are functioning correctly. We do not stop working at your property until everything is completed to our high standards.

Do you need to apply for house extension planning permission in Sittingbourne?

The need for planning permission is entirely dependent on the type of extension you opt for and how much you are planning to extend your property by. If you are planning a multi-storey extension, anything that extends beyond 3 metres of the original house rear wall will require planning permission. A single-storey extension should be a maximum of 4 metres high to avoid submitting a planning permission application. They also cannot extend beyond 3 metres for a semi-detached or 4 metres for a detached house. If you require further guidance on the planning process for your extension, we work with specialist architects that we can put you in contact with.


How much value does a house extension add to your Sittingbourne property?

Whether it’s a small house extension or multi-story project adding multiple rooms, any type of extension that you opt for will add value to your Sittingbourne property. How much value it adds will depend on the type you opt for, as well as other factors such as location and the current value of your home. The most popular choice to increase living space, a single-storey extension, can add between 5% and 8% to the value of your property in most cases.

What other house extension options do you have in Sittingbourne?

If you think building upwards rather than outwards would be a better option for your property, you should consider a loft conversion as a viable option. This is an effective alternative to gain an extra bedroom and make the most of the roof space in your Sittingbourne property. Alternatively, you could decide that an addition to your house that is completely separate is the best option. In which case, a garden room could let you create the additional living space you desire, with an office or an outside bar being popular options.
