Extensions in Courthouse 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.
- Local to Courthouse Green

Extensions across Courthouse Green and the CV6 district, including Bell Green, Edgwick and Foleshill. 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.

- Trees on clay near the build change the foundation depth and sometimes the design.
- Foundations are the biggest unknown in the budget, and the depth is set by the ground, not the design.
- The kitchen layout has to be settled before first fix, because it sets every socket and waste position.
- Removing the existing rear wall on a beam is what turns an extension into one room rather than two.
- A lawful development certificate is the document that answers a buyer's solicitor years later.
The work itself, in plain terms
Extension work across Courthouse Green and nearby Bell Green, Edgwick and Foleshill, from the foundations to the finished room.
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 extensions, cheaper per square metre because foundations and roof are shared, though more likely to need planning.
Side returns & side extensions
Side return infill on Victorian and Edwardian terraces, squaring off an awkward galley kitchen.
Planning & Building Control
We establish early whether the project is permitted development or needs an application, and build the approvals into the programme.
Groundworks & structure
Groundworks and structural work, including the trial holes and trees check that set foundation depth honestly.
Full fit-out
First and second fix, plastering, flooring and decoration — handed over as a finished room, not a shell.
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
Light planned through the whole depth, not just glazed at the far end.
Investors
Honest advice when the numbers say the extension will not return what it costs here.
The jobs that start with a phone call
- 01
Wiring, an outside light and the alarm sensor all cut off with the wall that came down.
- 02
A party wall notice served too late, holding up a start date that had already been booked.
- 03
New brickwork that reads as obviously new, because the mortar was never matched to the original.
- 04
Drains or an inspection chamber running directly under the proposed footprint.
- 05
A design drawn to the permitted development limit without checking what a previous owner already added.
- 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 Courthouse Green
Every quote starts with a survey. These are the things we look at on extension work in Courthouse Green, and why each one changes the recommendation.
Matching brick and roof tile
We identify the existing materials and check availability of a match. Where no match exists, it is better to design around the difference than to hope nobody notices.
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.
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.
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.
Light to the existing rooms
Extending across the back of a house can leave the middle dark. We flag it at survey so rooflights or an internal opening can be designed in rather than regretted.

Speak to us today0786 5778332Do you only work in Courthouse Green, or the surrounding streets too?
Both. Work in Courthouse Green usually takes us into Bell Green (about 0.4 miles away), Edgwick (about 0.5 miles away), Foleshill (about 0.5 miles away) and Little Heath (about 0.6 miles away) as well, and we quote for all of them on the same terms. There is no boundary line that changes the price.
How quickly can you get to Courthouse Green?
Quickly — it is about 1.9 miles north-east of the city centre. Short distances are the main reason we can offer same-week surveys and come back promptly if something needs a second look.
What happens about drainage and manholes?
If there is a public sewer or a manhole in the way you may need a build-over agreement from the water authority, and that takes time. Existing drains may need diverting, and new foul and surface water connections have to be designed and inspected. We check drainage at survey, because a manhole discovered after the foundations are set out is a genuinely expensive surprise.
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.
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.
Flat roof or pitched roof on an extension?
Flat is usually the answer on a single-storey rear extension because it keeps the height down under the permitted development limit and allows rooflights easily. Modern flat roofs in EPDM or GRP are long-lived and nothing like the felt roofs that gave flat roofs their reputation. Pitched roofs suit the house better in some cases but they raise the height, which can push the project into needing planning permission.
Will an extension add value?
Usually, though rarely pound for pound, and the ceiling is the top of the market for your street. Adding a bedroom or opening up a cramped ground floor tends to do better than simply adding area. Overdeveloping relative to the neighbours is the way to spend money you will not get back. We would rather say that at survey than after you have committed.
