Extensions in Allesley
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 across Allesley and the CV5 district, including Allesley Green, Mount Nod and Brownshill Green. Single and two-storey, side returns and wrap-arounds, built from foundations to finished room. We will tell you early whether your project is likely to fall under permitted development or need a planning application, because that changes the timescale more than the build does.
Working in Allesley
Allesley lies 2.5 miles north-west of Coventry city centre, in the CV5 postcode district.
Within walking distance you will find All Saints Parish Church and Anderson Garden, and we work on properties throughout the streets around them.
The nearest areas we also cover are Allesley Green (0.5 miles) and Mount Nod (0.9 miles), so work in Allesley sits inside the same run of the city.

- A quote with no written specification cannot be compared with another one.
- Removing the existing rear wall on a beam is what turns an extension into one room rather than two.
- New brick will not match eighty-year-old brick, so the junction is a design decision.
- On a semi or terrace, party wall notice is the norm rather than the exception.
- Foundations are the biggest unknown in the budget, and the depth is set by the ground, not the design.
The work itself, in plain terms
What we build around All Saints Parish Church and the rest of Allesley, and the stages each project goes through.
Single storey rear extensions
The most common project we build: a rear extension, sized where possible to stay within permitted development.
Two storey extensions
Two-storey builds from foundations up, including the bedroom-level disruption planned around realistically.
Side returns & side extensions
Filling the side alley to turn a narrow kitchen into a usable room, with rooflights to keep the middle of the house bright.
Planning & Building Control
Planning and Building Control handled as part of the job, with inspections scheduled rather than chased.
Groundworks & structure
Foundations sized to the actual ground conditions, and structural steel to engineer calculations.
Full fit-out
Complete fit-out including electrics, plumbing, heating, plastering and decoration.
Built around how you own the property
Growing families
The space you need without moving, with a programme you can plan family life around.
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
An extension started with no contingency, where the first surprise in the ground forced a visible compromise.
- 02
A quote accepted on price alone, with spoil removal and making good to the existing house both excluded.
- 03
New brickwork that reads as obviously new, because the mortar was never matched to the original.
- 04
Foundations priced at an assumed depth, with no rate agreed for what happens if it has to go deeper.
- 05
Drains or an inspection chamber running directly under the proposed footprint.
- 06
An extension that leaves the original back room dark, because all the glazing went in the new rear wall.
What we check on a property in Allesley
Every quote starts with a survey. These are the things we look at on extension work in Allesley, and why each one changes the recommendation.
Existing drainage and manholes
We locate drain runs and inspection chambers early. A build-over agreement takes time to obtain, and a manhole found after setting out is an expensive discovery.
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.
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.
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.
Services to be diverted
Gas meters, soil pipes, external taps, boiler flues and incoming supplies all tend to be exactly where the new wall goes. We identify them early so diversions are planned, not improvised.
Access for plant and materials
Whether a digger can reach the back garden, where a skip can stand and how far materials must be barrowed changes both method and price. Restricted access is workable but it has to be priced honestly.

Speak to us today0786 5778332Have you worked around All Saints Parish Church?
All Saints Parish Church is in the part of Allesley we cover, and extension work there is routine for us. Every quote still starts with a survey of the actual property, because no two are the same even on one street.
Is Allesley inside your normal service area?
Yes, and so is everything immediately around it: Allesley Green (about 0.5 miles away), Mount Nod (about 0.9 miles away), Brownshill Green (about 1.1 miles away) and Eastern Green (about 1.2 miles away). We cover the whole of Coventry, so there is no travel charge for any of them and no minimum job value.
How long does an extension take to build?
A straightforward single-storey rear extension is typically somewhere around three to four months on site; a two-storey is longer. The part people underestimate is everything before that: design, structural calculations, planning if needed, Building Control and lead times on glazing and steel can easily add as long again. We give a programme that includes those stages because a build-only timescale is not a date you can plan around.
How much glass can we have?
More than people expect, with caveats. Building Regulations limit heat loss across the whole building rather than capping glazing outright, so large openings are achievable if the rest of the fabric compensates. The practical limits are structural — a wide opening needs a bigger steel — and comfort: a fully south-facing glass box overheats in summer unless shading or solar-control glass is designed in.
Can you work from our architect's drawings?
Yes, and it is how most of our extension work comes to us. We price from the drawings and structural calculations, flag anything that looks buildable only in theory, and liaise with the designer during the build. Where there are no drawings yet we can advise on what level of detail you need before anyone can give you a price worth comparing.
What is the Party Wall Act and does my extension trigger it?
It applies if you build on the boundary line, cut into a shared wall, or excavate within 3m of a neighbouring structure to a depth below its foundations — which most extensions on a semi or terrace do. You serve notice in advance; the neighbour consents or surveyors agree an award. Notice periods run to two months, so it needs starting early, not when the scaffold arrives.
What is the difference between planning permission and Building Regulations?
They are separate and you can need one, both or neither. Planning is about whether you may build it: size, siting, appearance and impact on neighbours. Building Regulations are about whether it is built safely and properly: structure, insulation, fire, ventilation, drainage. An extension under permitted development still needs Building Regulations approval. People regularly assume planning approval covers both, and it does not.
