Extensions in Bell 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.

Extensions across Bell Green and the CV6 district, including Courthouse Green, Little Heath and Henley 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 Bell Green
Bell Green lies 2.4 miles north-east of Coventry city centre, in the CV6 postcode district.
Within walking distance you will find Kingdom Hall and Lido Extra, and we work on properties throughout the streets around them.
The nearest areas we also cover are Courthouse Green (0.4 miles) and Little Heath (0.5 miles), so work in Bell Green sits inside the same run of the city.
- Kingdom Hall
- Lido Extra
- Bell Green Wildlife Conservation Area
- Northpoint Church
- Courthouse Green Primary School
- Armfield St. green space
- Peg the footprint out on the ground before you commit to a depth — it changes minds.
- Permitted development never removes the need for Building Regulations approval.
- On a semi or terrace, party wall notice is the norm rather than the exception.
- Hold 10 to 15 per cent contingency back rather than committing all of it to the build.
- A quote with no written specification cannot be compared with another one.
The work itself, in plain terms
The extension work we carry out on Bell Green properties, from groundworks and structure to glazing and full fit-out.
Single storey rear extensions
Single-storey rear extensions — groundworks, structure, flat or pitched roof, glazing and full fit-out.
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
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
A plan that works around the family staying in the house while the work happens.
Open-plan projects
Light planned through the whole depth, not just glazed at the far end.
Investors
Full paperwork at the end, because the certificates are what protect the value.
The jobs that start with a phone call
- 01
Sockets in the wrong places, because the kitchen layout was decided after first fix.
- 02
A design drawn to the permitted development limit without checking what a previous owner already added.
- 03
A flat roof with inadequate fall, ponding within a year of being finished.
- 04
Drains or an inspection chamber running directly under the proposed footprint.
- 05
Foundations priced at an assumed depth, with no rate agreed for what happens if it has to go deeper.
- 06
New brickwork that reads as obviously new, because the mortar was never matched to the original.
What we check on a property in Bell Green
Every quote starts with a survey. These are the things we look at on extension work in Bell 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.
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.
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.
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.
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.

Speak to us today0786 5778332Have you worked around Kingdom Hall?
Kingdom Hall is in the part of Bell Green 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 Bell Green inside your normal service area?
Yes, and so is everything immediately around it: Courthouse Green (about 0.4 miles away), Little Heath (about 0.5 miles away), Henley Green (about 0.5 miles away) and Foleshill (about 0.8 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.
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.
Do you build for landlords and commercial clients?
Yes. We work for landlords extending rental property and for commercial clients, and we are used to working around tenants, trading hours and phased handovers. For rental property we will also point out where a layout change affects licensing or room-size requirements, which is easier to design around than to correct.
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.
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.
