Extensions in Hawkesbury
Most extensions are decided long before anyone digs: how deep you can go without a planning application, what is in the ground, and where the daylight will come from once the back wall moves.

Extensions in Hawkesbury, the area around Hawkesbury Village Green. Single-storey rear, side return, wrap-around and two-storey, built from foundations to finished room with proper structural design behind the open spans. We are honest at survey about what the plot and the existing structure will take.
Working in Hawkesbury
Hawkesbury is at the far north-east edge of our area, in the CV6 postcode district, where the Coventry and Oxford canals meet at Hawkesbury Junction.
Properties out this way are often more exposed than those in the middle of the city, and exposure is what finds the weak points in a roof: the verge, the ridge and the flashings go first on a windy plot.
It is still inside our normal working area, with no travel surcharge.
- Hawkesbury Village Green
- Hawkesbury Junction
- Grangehurst Primary School
- New brick will not match eighty-year-old brick, so the junction is a design decision.
- Permitted development never removes the need for Building Regulations approval.
- Removing the existing rear wall on a beam is what turns an extension into one room rather than two.
- Rooflights over the junction are what stop the original back room going dark.
- A lawful development certificate is the document that answers a buyer's solicitor years later.
The work itself, in plain terms
The extension work we take on across Hawkesbury (CV6), from a single-storey rear to a full two-storey build.
Single storey rear extensions
Rear extensions from foundations to finished room, with the light to the existing house designed in rather than lost.
Two storey extensions
Two-storey builds from foundations up, including the bedroom-level disruption planned around realistically.
Side returns & side extensions
Side returns and side extensions — modest in area, substantial in how the ground floor actually works.
Planning & Building Control
Guidance on which approvals apply, including lawful development certificates, party wall notices and build-over agreements.
Groundworks & structure
Excavation, foundations, drainage and structure — the stages that decide whether everything above goes smoothly.
Full fit-out
Everything after the shell: services, finishes and the snagging done before we call it complete.
Built around how you own the property
Growing families
More usable space without changing schools, neighbours or the commute.
Open-plan projects
Rear builds combined with removing the original back wall, which is where the transformation actually comes from.
Investors
Extensions costed against the realistic ceiling value for the street, not for the postcode in general.
The jobs that start with a phone call
- 01
A flat roof with inadequate fall, ponding within a year of being finished.
- 02
A large tree close to the build on clay soil, which changes the foundation depth and sometimes the design.
- 03
Drains or an inspection chamber running directly under the proposed footprint.
- 04
A party wall notice served too late, holding up a start date that had already been booked.
- 05
A quote accepted on price alone, with spoil removal and making good to the existing house both excluded.
- 06
A finished extension with a step down into it, because the slab level was set before anyone measured the house floor.
What we check on a property in Hawkesbury
Every quote starts with a survey. These are the things we look at on extension work in Hawkesbury, and why each one changes the recommendation.
The existing structure being opened into
What carries the wall you are opening up, and what sits above it, determines the steel and the propping. We establish this before quoting, not when the plaster comes off.
Levels, inside and out
The relationship between the existing floor, the new floor and external ground level affects damp detailing, thresholds and step-free access. It is much easier to resolve on paper.
Protecting the rest of the house
We plan dust screens, floor protection and the route in and out before starting. Living through a build is tolerable if the mess is contained to where the work is.
Building Control route and inspection points
We establish which body is inspecting and when they need to attend. Inspections built into the programme never delay a job; inspections remembered late always do.
Neighbour considerations
Shared drives, overhanging trees, fence ownership and where a neighbour parks all affect the build. A conversation at survey stage prevents most of the disputes we have seen.
Heating capacity
A bigger house needs more heat. We check whether the existing boiler and emitters can serve the extended property, because discovering otherwise in November is avoidable.

Extensions in Hawkesbury — your questions answered
Still have a question? Our local team is happy to help — no pressure, no jargon.
Speak to us today0786 5778332Do you cover the CV6 postcode area?
Yes. Hawkesbury falls in CV6, which is part of our normal working area, so there is no travel surcharge and no minimum job value.
Which part of Hawkesbury do you cover?
All of it — the streets around Hawkesbury Village Green included. Where a property sits matters less to us than what the access is like, which is something we look at on the survey rather than guessing from an address.
How deep do the foundations need to be?
That depends on the ground, not on the extension. Foundation depth is driven by soil type, the water table, and especially nearby trees — clay soils near mature trees can require foundations well beyond the usual minimum. Building Control inspect the excavation before concrete goes in and will ask for them deeper if the ground says so. This is the single most common reason a groundworks budget moves.
How do you handle changes once work has started?
Priced and agreed in writing before they are built. Changes are normal — seeing the space makes people reconsider — but they cost more the later they come, and a change after first fix can mean undoing finished work. We will always tell you what a change costs and what it does to the programme before doing it, not afterwards.
What is a side return extension?
It is the infill of the narrow alley running alongside the back of a house, common on Victorian and Edwardian terraces. The strip is usually only two or three metres wide, so the gain in floor area is modest, but the gain in usable space is large because it squares off an awkward galley kitchen. Rooflights matter here: filling the side return can darken the middle of the house unless light is designed back in.
Do I need a structural engineer?
Yes, for anything involving a beam, an opening in a load-bearing wall, or unusual foundations — which is nearly every extension. The engineer sizes the steel and specifies the bearings and padstones, and Building Control want to see those calculations. It is a modest cost relative to the build and it is not an area where experience substitutes for arithmetic.
Is a two-storey extension much more expensive than single-storey?
Per square metre it is usually cheaper, because the most expensive elements — foundations and roof — are shared across two floors. The total is obviously higher, and two-storey work is far more likely to need planning permission, more likely to engage the Party Wall Act, and more disruptive because it affects bedrooms. The per-metre efficiency is real, but it is not the only consideration.
