Add a businessThe cost of house extensions depends on your location, plus the size, location, and complexity of the house extension itself. In the UK, you can expect to pay these house extension costs per m²:
Basic single-storey extension: £1,500 to £3,000+ per m²
Two-storey extension: £2,000 to £3,000+ per m²
With that being so, a 3-metre house extension could cost you between £25,000 and £60,000+, depending on whether it’s single or double storey, and the finish you choose.
You may also need to budget for architectural design, planning fees, VAT, and internal finishes, as many house extension builders near you might not include these costs in their quotes. This is part of why house extension prices can seem to vary by so much.
For an accurate quote, contact at least 3 house extension builders near you who can assess your site and project scope. With several quotes to compare, you can better understand what represents fair value for your project.

A typical single-storey house extension takes 10 to 14 weeks to complete once construction begins. Two-storey extensions or those requiring structural changes will take longer.
The full process – including planning, design, approvals, and construction – can take several months, so plan well in advance.
The most reputable house extension builders near you will provide a clear timeline with stages, milestones, and allowances for weather or delays. Everything should be clear before you fully commit to a local builder, let alone before the work starts.
Look for house extension builders in Mitcham who are:
Positively rated and reviewed on Yell
Fully covered with public liability insurance
Experienced with projects of a similar scope
Transparent with timelines and pricing
Able to manage planning permission and other administrative tasks
Familiar with local building regulations
You can start exploring Mitcham house extension companies to compare options, before contacting anyone. Then, request and compare multiple quotes, view some of their past projects, and ask for references from previous clients before hiring.
Yes, you can usually stay in your home while the house extension is being built, especially for rear or side extensions. Just remember that it may be a noisy, dusty, and disruptive environment during the project!
If the work involves removing walls, major plumbing changes, or temporary loss of kitchen or bathroom access, your builder may suggest moving out for part of the project.
Once the scope of your project is decided, you can ask your local house extension builder what to expect, and they’ll help plan around your living arrangements and limitations.
Some house extensions fall under Permitted Development Rights, meaning you may not need full planning permission; especially for modest rear extensions or side returns. Yet, you’ll still need building regulations approval.
If you’re planning a more expansive house extension, it’s more likely you’ll need planning permission. As always, it's best to check with your local planning authority or work with a house extension planner or architect who can advise.
In many cases, the house extension builders in Mitcham can take care of the entire process – including attaining planning permission, when it’s required – which is far easier than dealing with these matters yourself.
