Extensions in Henley Green
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.

Working in Henley Green
Henley Green lies 2.6 miles north-east of Coventry city centre, in the CV2 postcode district.
Within walking distance you will find Castlewood School and Moat House & Castle Wood School Campus, and we work on properties throughout the streets around them.
The nearest areas we also cover are Bell Green (0.5 miles) and Courthouse Green (0.9 miles), so work in Henley Green sits inside the same run of the city.

- A lawful development certificate is the document that answers a buyer's solicitor years later.
- Hold 10 to 15 per cent contingency back rather than committing all of it to the build.
- The kitchen layout has to be settled before first fix, because it sets every socket and waste position.
- On a semi or terrace, party wall notice is the norm rather than the exception.
- A quote with no written specification cannot be compared with another one.
The work itself, in plain terms
Extension work across Henley Green and nearby Bell Green, Courthouse Green and Walsgrave, from the foundations to the finished room.
Single storey rear extensions
The most common project we build: a rear extension, sized where possible to stay within permitted development.
Two storey extensions
Adding space on both floors — more efficient per metre, and more involved on approvals and party wall notices.
Side returns & side extensions
Side returns and side extensions — modest in area, substantial in how the ground floor actually works.
Planning & Building Control
Planning and Building Control handled as part of the job, with inspections scheduled rather than chased.
Groundworks & structure
Groundworks and structural work, including the trial holes and trees check that set foundation depth honestly.
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
A plan that works around the family staying in the house while the work happens.
Open-plan projects
The structural opening sized properly, because a narrow doorway wastes the extension behind it.
Investors
A clear view of what the work adds against what it costs, before anything is committed.
The jobs that start with a phone call
- 01
Foundations priced at an assumed depth, with no rate agreed for what happens if it has to go deeper.
- 02
An extension started with no contingency, where the first surprise in the ground forced a visible compromise.
- 03
An extension that leaves the original back room dark, because all the glazing went in the new rear wall.
- 04
Wiring, an outside light and the alarm sensor all cut off with the wall that came down.
- 05
A quote accepted on price alone, with spoil removal and making good to the existing house both excluded.
- 06
New brickwork that reads as obviously new, because the mortar was never matched to the original.
What we check on a property in Henley Green
Every quote starts with a survey. These are the things we look at on extension work in Henley Green, and why each one changes the recommendation.
Roof junction with the existing house
How the new roof meets the old is where extensions most often leak. We look at the abutment detail, the flashing and the height relationship at survey.
Contingency and what could move the price
We say plainly which parts of the quote are firm and which depend on what we find — usually foundations and the existing structure — so the contingency is a planned figure rather than a shock.
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.
Existing foundations
Where the new structure ties into the old, we need to know what the existing foundations are. Trial holes are sometimes the only honest way to find out.
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.
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.

Speak to us today0786 5778332How far is Henley Green from your base?
Henley Green is roughly 2.6 miles north-east of Coventry city centre. That is close enough that a survey can normally be arranged within a few days, and close enough that coming back afterwards is never a problem.
Do you only work in Henley Green, or the surrounding streets too?
Both. Work in Henley Green usually takes us into Bell Green (about 0.5 miles away), Courthouse Green (about 0.9 miles away), Walsgrave (about 0.9 miles away) and Wyken (about 1 mile away) as well, and we quote for all of them on the same terms. There is no boundary line that changes the price.
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.
What about insulation and energy efficiency?
New extensions have to meet current Building Regulations for thermal performance, which is considerably better than most existing housing. The practical consequence is worth knowing: a well-insulated extension attached to a poorly insulated house can make the older rooms feel colder by comparison, and heating systems sized for the original house may need reassessing. Worth thinking about at design stage rather than discovering in the first winter.
Should we extend or move?
Worth doing the arithmetic properly. Moving costs stamp duty, agent and legal fees and removals, with nothing added to the property you leave. Extending costs the build and some months of disruption, and leaves you in the same place with the same neighbours and schools. Extending usually wins financially; moving wins when the location or the plot is the actual problem, and no amount of building fixes that.
What are the rules on building near a boundary?
Under permitted development a single-storey extension within two metres of a boundary is limited to three metres at the eaves, and side extensions have their own width limits. Separately, you need to be able to build and maintain the wall, which may require access to a neighbour's land. Building right up to a line is possible but it changes the method and the neighbour conversations, so it is worth deciding early.
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.
