Type of extensions we offer
Pricing from drawings • Built to approved plans • Managed on-site delivery
Rear Extensions
Ideal for creating larger kitchens and open-plan living spaces that connect better with the garden. A rear extension is one of the most effective ways to add space and improve everyday living.
Side Return
Perfect for making use of narrow or unused space at the side of your property. This option is popular in Ealing homes for widening kitchens and improving layout flow.
Wraparound
A combination of rear and side extensions that significantly increases ground floor space. This is a strong choice for homeowners looking to fully transform their layout.
Double Storey
Adds extra space both downstairs and upstairs, often including additional bedrooms or bathrooms. A practical option for growing families who need long-term space solutions.
Planning Your House Extension: What You Need to Know
Whether you’re ready to build or still exploring, we provide clear, practical advice to help you move forward
Recent UK research shows that around 26% of London homeowners now choose to renovate rather than move, largely due to these rising costs and wider affordability pressures.
In this context, extending your existing home becomes a practical alternative to moving. Rather than absorbing large one-off costs to change location, a well-planned extension allows you to unlock additional space within your current property—tailored to your layout, site constraints, and long-term needs.
We help solve this exact problem by assessing what is realistically achievable on your property and how different extension options perform in terms of cost, value, and buildability. Download our checklist guide to help you plan your house extension with clarity.
Clear Responsibility Throughout Your Build
Your house extension is managed through one dedicated point of contact who oversees the entire build on site, coordinates all trades, and ensures the project progresses as planned. This avoids confusion, miscommunication, and delays that often happen when homeowners are dealing with multiple people across different stages of the build.
With one person responsible for delivery, decisions are clearer, communication is faster, and your project stays properly controlled from start to finish.
We also ensure that any site issues or variations are addressed quickly, so the build continues without unnecessary downtime. This helps maintain consistent progress and reduces the risk of costly delays. Regular coordination between trades ensures each stage transitions smoothly into the next without disruption.
How Much Does a House Extension in Ealing Cost?
House extension costs in Ealing typically range from around £1,800 to £3,500+ per m², depending on size, structure, access, and the level of finish. As a general guide:
- Smaller or basic single-storey extensions tend to sit at the lower end of this range
- Standard residential extensions fall within the mid-range
- Larger or high-spec builds with structural complexity sit at the higher end
Every project is different, and the final cost depends on your property and build requirements.
We provide clear, itemised quotations based on your drawings or site visit, so you can see exactly how your budget is allocated before any work begins. If you already have plans, we can price your extension accurately from drawings. If not, we can give you a realistic cost expectation based on similar projects in Ealing before you commit to anything.

Side Return + Refurb
Ernest and the team did a fantastic side return, full kitchen and garden renovation over the summer on our Victorian terrace in St Margarets. They were impeccable – no nonsense, honest and hard working (…). They will be used for our next project, without a doubt.

Side return
I can’t recommend Ernest and his team highly enough. From beginning to end they were incredibly professional and diligent making sure that we were fully informed of progress and consulted on big and small decisions. Ernest was in particular excellent at coordinating all of the different tradesmen so that the job ran on time and to plan (…)

The first, an entire home renovation including side extension, creating an open plan kitchen, chimney breast removal over two floors, new window fitting and external rendering.
