House Extensions in Wirral – Expert Builders for Every Home
Extending your home is one of the most effective ways to create more space without the stress or expense of moving. Across Wirral, many families discover that their needs have grown with them and their home starts feeling small or outdated and needs changing. A carefully planned house extension provides the solution. It can create a larger kitchen, add a bedroom, or deliver an open-plan living space that connects to the garden.
By choosing to extend, you gain comfort now and also increase the long-term value of your home.
At CNR Construction, we know a house extension is about more than just adding extra floor space. The aim is to create a room or area that feels like it has always been part of your home.

Why Choose a Home Extension in Wirral?
A home extension gives you far more control than moving into a new property. You are not restricted by the local housing market or by what other homes look like. Instead, you can design the exact layout you need.
For example, some homeowners want a large kitchen-diner that becomes the central hub of family life. Others prefer a front house extension to improve the entrance of the property and increase kerb appeal. More practical builds, such as side returns, make use of otherwise wasted outdoor areas.
Another reason many people choose an extension over moving is cost. While the cost of house extension projects varies, it is often less than the expense of buying a larger property and paying legal fees, stamp duty, and moving costs. An extension also adds value to your home, making it an investment as well as an improvement.

One of Our Extensions
"Ollie and his team built us a single-storey rear extension in Pensby to create a larger kitchen and dining area. Everything was completed to a high standard, from the brickwork to the roof and RSJ install. They were clean, on time every day, and kept us informed throughout. Can’t recommend them enough for anyone looking for a quality extension builder in the Wirral."

House Extension Cost and Prices
One of the first questions people usually ask is how much does a house extension cost. The cost will depend on what type of house extension you desire. A smaller build, like a 3 meter house extension, is generally more affordable, while a larger double storey project requires a bigger budget. Both, though, can completely change the way you use your home.
Some homeowners like to think in terms of the house extension cost per m2, while others prefer to compare total house extension prices for the whole project. Either approach works, but it’s worth checking the detail behind each quote. When comparing companies for house extensions, make sure the essentials are included. That being the foundations, structural work, electrics, plumbing, and finishes. It’s easy to be drawn to the lowest price, but not every builder lists everything up front.
At CNR Construction, we keep it straightforward. We give you a full breakdown of the cost of house extension work before we start. No hidden extras, no vague figures. Just a clear estimate so you can plan with confidence.
FAQ's
Sometimes. Smaller rear builds often fall under permitted development, which means you don’t need a full application. But if you’re looking at a front extension for your house, you’ll almost certainly need planning approval. We check this for you before any work begins, and if an application is required, we'll help handle the process with you.
It depends on the project. A simple single-storey extension can often be finished in 8 to 10 weeks. A larger double storey or wrap-around build might take 12 to 16 weeks. Weather delays, tricky access, or structural changes can also add time. We always give you a schedule before starting, and we keep you updated if anything changes along the way.
Yes, that’s always the goal. We match bricks, tiles, and windows so the new build feels like it belongs. Inside, we look at layout and finishes so the flow makes sense with the rest of your home. Done right, an extension should look like it’s always been there, whether it’s at back, side, or a front extension house project.
Yes. We cover all types of extensions including rear builds, side returns, and larger wrap-arounds. A front extension in front of the house can be a smart way to create extra hallway space, a bigger lounge, or even a porch. These often need planning approval, so we’ll advise on what’s possible and guide you through the process.
It really depends on what you want. A modest single-storey kitchen extension will cost less than a large two-storey or bespoke extension. Location and access can also influence the price. That’s why we recommend a free consultation as it lets us see your home, understand your plans, and give you a clear quote. That way, you’ll know the cost before making any decisions.
There’s no fixed figure, but we can usually give a ballpark during your consultation. A simple rear extension is at the lower end, while a double storey or bespoke design will cost more per square metre. Finishes also matter — standard fittings cost less, while features like skylights, bi-fold doors, or a custom kitchen raise the price. We explain the house extension cost per m2 clearly in your quote so you know exactly what’s driving the numbers.
