Your questions answered

A home extension is a major renovation project. It’s only natural that you have a few questions whirring around your head. We answer some of the most common ones, below.

Where do I start if I want to build an extension?

First things first, you want to find a reputable person/firm for the job. It’s a good idea to do your research first and even better, get a recommendation from a trusted source.

Building a house extension is a costly job and needs to be right so it’s vital that you employ the right builder for you and your upcoming build.

For step-by-step guidance on the renovation process, check out our comprehensive guide to building an extension.

Can you build a house extension without planning permission?

Depending on the size of the extension you wish to build, you may or may not need planning permission. You can build up to six metres (or eight, if your house is detached) without planning permission.

You must acquire planning permission if your intended build will be higher than the highest part of the existing roof.

Single-storey rear extensions cannot extend beyond the back wall of the original house by more than four metres for a detached house, or more than three metres for a terraced or semi-detached house.

Single-storey extensions can’t exceed four metres in height without planning permission.

For side extensions, they cannot go beyond four metres in height, can only be one storey, and can only be up to half the width of your house.

Do I need an architect for an extension?

Hiring an architect is not a legal requirement for building an extension, but it is highly recommended.

Their expertise will ensure compliance, helping to navigate complex regulations. They will also ensure your extension looks and acts the part – delivering the style and practicality you desire – within your designated budget.

What is the average cost of an extension?

Like all home projects, the cost of building an extension will depend on many factors. This includes where you live, the size of the extension, where you want the extension, the materials you wish to use, and how long the project is going to take.

However, the average cost for a 20m² extension is £48,000. You can expect a house extension to add 10-20% to your home’s overall value.

Why should I hire a local house extension builder near me?

Peace of mind. Hiring a house extension builder local to you will ensure that the extension is built properly and will follow all of the necessary regulations.

Reliable. Employing a house extension builder with a good reputation will mean that they are reliable. They will turn up on time, give you a fair quote, and will see the project through to completion.

Avoid costly repairs. If you try and tackle building an extension yourself or enlist the help of an unqualified friend, this may end up with you spending more money than you would have done in the first place.

How do I find a reputable house extension builder near me?

If you’re ready to find the best home extension builders near you, you might be wondering how to choose the right one for the job. Here are some tips.

Verify their credentials. Check to see if they have any appropriate credentials for the job that they will be completing for you. Also, word of mouth is a wonderful thing. If someone you know has recommended that specific tradesperson then that’s a great sign.

Read reviews. Check what other homeowners have said about any house extension builders near you before you hire them for the job.

Compare quotes. It’s always best to get at least three quotes from qualified builders before you make your selection to ensure you’re getting the best professional for the job at the best price.

Check public liability insurance. All reputable tradespeople should have public liability insurance to cover them if things don’t go to plan.

Ask when they take payment. Your house extension builder should never take full payment upfront. Instead, you should be able to pay at least part of the fee after the work is complete.

Use Checkatrade! Our approved members have to pass up to 12 checks. They also regularly receive reviews on all aspects of their work. So you know you’re hiring someone you can trust.
