Extensions in Lower Eastern 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.

Survey first, then a fixed written quote and a programme.
Working in Lower Eastern Green
Lower Eastern Green is the southern side of Eastern Green, in the CV5 postcode district on the western edge of the city near Mount Nod and Allesley Green.
As with the rest of Eastern Green, much of the housing is post-war onwards, which puts flat roofs, fascias and guttering, and driveway drainage at the top of the list of what we get called out to.
If your address sits between the two, it makes no difference to us: same team, same pricing.
- Park Hill Primary School
- Mount Nod Primary School
- Good Shepherd Lutheran Church
- A rear extension of 4m detached or 3m semi/terraced is generally permitted development, subject to conditions.
- Hold 10 to 15 per cent contingency back rather than committing all of it to the build.
- 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.
The work itself, in plain terms
The extension work we carry out on Lower Eastern Green properties, from groundworks and structure to glazing and full fit-out.
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
Guidance on which approvals apply, including lawful development certificates, party wall notices and build-over agreements.
Groundworks & structure
Foundations sized to the actual ground conditions, and structural steel to engineer calculations.
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
Room to grow in the house you already have, costed against what moving would actually take.
Open-plan projects
Rear builds combined with removing the original back wall, which is where the transformation actually comes from.
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
Drains or an inspection chamber running directly under the proposed footprint.
- 02
A design drawn to the permitted development limit without checking what a previous owner already added.
- 03
Foundations priced at an assumed depth, with no rate agreed for what happens if it has to go deeper.
- 04
A flat roof with inadequate fall, ponding within a year of being finished.
- 05
A large tree close to the build on clay soil, which changes the foundation depth and sometimes the design.
- 06
Sockets in the wrong places, because the kitchen layout was decided after first fix.
What we check on a property in Lower Eastern Green
Every quote starts with a survey. These are the things we look at on extension work in Lower Eastern Green, and why each one changes the recommendation.
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.
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.
Boundary positions and the Party Wall Act
We check where the actual boundary runs and whether the work triggers party wall notices. Notice periods run to two months, so this belongs at the start of the programme.
Glazing orientation and overheating
A large glazed elevation facing south behaves very differently from one facing north. We raise shading and glass specification at design stage rather than after the first summer.
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.
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.
Simple, transparent, no pressure

Speak to us today0786 5778332Have you worked around Park Hill Primary School?
Park Hill Primary School is in the part of Lower Eastern 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 Lower Eastern Green in your coverage?
It is. Lower Eastern Green sits in the CV5 district and we work there regularly. Give us the full postcode when you call and we can be specific about survey dates.
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.
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.
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.
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.
Can we stay living in the house during the work?
For most single-storey rear extensions, yes, with real disruption at particular points — principally when the opening is made between old and new, when services are moved, and during any floor work. Where a kitchen is being extended into, a temporary kitchen is worth planning for. We sequence work to keep the house usable and tell you honestly which weeks will be the difficult ones.
