Back-of-house extension drawings for Charnwood homes — the glazed kitchen-diner across the rear, drawn to Charnwood Borough Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Charnwood Borough Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. Charnwood contains Barkby and Barkby Thorpe, Beeby, Birstall conservation areas, so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. In conservation areas such as Barkby and Barkby Thorpe, Beeby and Birstall those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Charnwood is determined against an 8-week statutory target.
Barkby and Barkby Thorpe (designated conservation area), Beeby (designated conservation area), Birstall (designated conservation area), Cossington (designated conservation area), Cropston (designated conservation area), Hoton (designated conservation area), Markfield (designated conservation area), Newtown Linford (designated conservation area), Birstall East & Wanlip (ward of Charnwood), Forest Bradgate (ward of Charnwood), Rothley Brook (ward of Charnwood), Sileby & Seagrave (ward of Charnwood), South Charnwood (ward of Charnwood), The Wolds (ward of Charnwood) and Wreake Valley (ward of Charnwood) — these are the Charnwood pockets our drawings cover most. Heritage designations here include Barkby and Barkby Thorpe, Beeby, Birstall, Cossington, Cropston, Hoton, Markfield and Newtown Linford. Charnwood Borough Council weighs each proposal against Charnwood Borough Council's development plan and the design policies it applies to householder applications, where the 18,820 homes here are 10% 1965-1972, 9% pre-1900, 7% 1930-1939, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow-pitched roofs and integral garages typical of that period's building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, over late-1960s and early-1970s houses (10% of 18,820 homes), Victorian and earlier houses (9%) and 1930s semi-detached and detached houses (7%).
Before anything is drawn we check your address against the designations that apply in Charnwood: Barkby and Barkby Thorpe (designated conservation area), Beeby (designated conservation area), Birstall (designated conservation area), Cossington (designated conservation area), Cropston (designated conservation area), Hoton (designated conservation area), Markfield (designated conservation area) and Newtown Linford (designated conservation area). Inside those boundaries permitted development is curtailed and Charnwood Borough Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.
Beyond the designated areas, Charnwood takes in Birstall East & Wanlip, Forest Bradgate, Rothley Brook, Sileby & Seagrave, South Charnwood, The Wolds and Wreake Valley. No Article 4 direction is recorded for Charnwood Borough Council, but the district's 8 conservation areas still limit permitted development on those streets.
On stock, Charnwood is late-1960s and early-1970s houses (10% of 18,820 homes), Victorian and earlier houses (9%) and 1930s semi-detached and detached houses (7%) — which is why shallow-pitched roofs and integral garages typical of that period's building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building govern what a loft or rear projection can realistically be. Charnwood Borough Council decided 495 householder applications in the latest published year and granted 88%, with 72% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Charnwood runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.
Charnwood Borough Council also decides for Birstall East & Wanlip, Forest Bradgate, Rothley Brook, Sileby & Seagrave, South Charnwood, The Wolds and Wreake Valley, so a decision in Charnwood sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.

The rear extension is the workhorse of Charnwood home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from late-1960s and early-1970s houses (10% of 18,820 homes), Victorian and earlier houses (9%) and 1930s semi-detached and detached houses (7%), most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Charnwood Borough Council scrutinises. The council reads the proposal against Charnwood Borough Council's development plan and the design policies it applies to householder applications, and the first line an officer draws is the 45-degree splay from the neighbour's nearest window.
So the drawings live or die on geometry. We set the depth against the exact permitted-development figure, hold the eaves and the flat-roof or lantern build-up under the 4-metre height ceiling, and show the projection tested against both the 45-degree plan angle and the 25-degree section angle to the neighbouring windows. Charnwood contains Barkby and Barkby Thorpe, Beeby, Birstall conservation areas, so materials, fenestration and roof form are assessed against the appraisal, so the rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — Barkby and Barkby Thorpe, Beeby, Birstall, Cossington, Cropston, Hoton, Markfield and Newtown Linford among Charnwood's — the larger-home extension route is switched off and even a modest rear addition needs consent. No Article 4 direction is recorded for Charnwood Borough Council, but the district's 8 conservation areas still limit permitted development on those streets. We confirm the designation before the survey.
Many single-storey rear extensions in Charnwood are permitted development and need no application. You will normally need to apply to Charnwood Borough Council, or use the larger-home prior-approval route, if any of these apply:
We draw the depth, the roof build-up and the daylight splays to each neighbour on the page — the tests Charnwood Borough Council's officers apply first — and submit a validation-complete pack, whether that is a lawful development certificate, a larger-home prior-approval notice or a full householder application.
Below is Charnwood Borough Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Charnwood Borough Council granted 88% of 495 householder decisions in the year to 31 March 2026, 72% of them inside eight weeks. Rear extensions turn most often on neighbour daylight and depth, so a drawing pack that proves those tests upfront is decided faster and refused less often than a DIY submission.

Across Barkby and Barkby Thorpe, Beeby and Birstall, the approved rear extension is typically a single-storey glazed box within the depth limit, roofed either flat with a lantern or in a shallow mono-pitch, and finished in brick or render to match the host wall. On the borough's late-1960s and early-1970s houses (10% of 18,820 homes), keeping the projection to the permitted-development figure often avoids an application entirely; where owners want the full 6 metres, the larger-home route succeeds when the neighbour-consultation period passes without a sustained objection.
The 18,820 homes here are 10% 1965-1972, 9% pre-1900, 7% 1930-1939, which is what sets the realistic roof and rear-projection options. We keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Charnwood Borough Council expects — so the back elevation answers the amenity case before a neighbour can lodge one. Two-storey rear extensions we draw with the 7-metre boundary gap and privacy screening resolved on the plan.
We draw rear extensions on every street in the borough. A few of the neighbourhoods where Charnwood back-of-house projects come up most often:

How far you can extend at the back in Charnwood depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Charnwood Borough Council checks |
|---|---|---|---|
| Standard permitted development | 3m terrace/semi · 4m detached | Lawful development certificate (optional) | Depth, 4m height, materials |
| Larger-home prior approval | 6m terrace/semi · 8m detached | Prior-approval notice + neighbour consultation | Neighbour objections on amenity |
| Full householder application | Beyond the above, or two-storey | Full planning permission | Daylight (45°/25°), bulk, garden retained |
| Conservation area | Case by case | Full planning permission | Character, roof form, boundary treatment |
The larger-home route is switched off on designated land — conservation areas such as Barkby and Barkby Thorpe and Beeby and Article 4 streets need a full application.
A fixed process built around how Charnwood Borough Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Charnwood postcode and house type. We confirm your conservation and Article 4 status, how much rear-extension depth you have under permitted development, and score your odds against live Charnwood Borough Council decisions.
We measure the original rear wall, floor and eaves levels, side and rear boundary distances and the neighbours' window positions — the numbers the depth limit and daylight splays depend on.
Chartered designers develop the single or two-storey rear extension to your brief, drawn inside the permitted-development limits or to Charnwood Borough Council's extension design guidance, with the daylight angles shown.
We submit the certificate, prior-approval notice or application, handle validation and case-officer queries, and revise the drawings free until Charnwood Borough Council issues its decision.
Often not. A single-storey rear extension up to 3 metres deep on a terrace or semi, or 4 metres on a detached house, and no higher than 4 metres, is usually permitted development in Charnwood. You will need to involve Charnwood Borough Council for anything deeper via the larger-home route, for two-storey rear extensions, and for any rear extension in a conservation area such as Barkby and Barkby Thorpe and Beeby, where those permitted-development rights fall away.
The larger-home extension scheme lets a single-storey rear extension reach 6 metres on a terrace or semi, or 8 metres on a detached house — double the standard allowance. It is not automatic: you submit a prior-approval notification to Charnwood Borough Council, neighbours are consulted, and if one objects on amenity grounds the council rules on it. It also does not apply on designated land such as Charnwood's conservation areas.
It is the daylight test Charnwood Borough Council applies to protect neighbours. Drawn on plan, a line at 45 degrees from the midpoint of the neighbour's nearest ground-floor window should not be crossed by your extension; a companion 25-degree line is checked in section. If the projection breaches it, the extension is likely to be shortened or refused, so we test and prove it on the drawings before submission.
A two-storey rear extension almost always needs a full householder application to Charnwood Borough Council, as it sits outside permitted development on most homes. The council checks that it stays at least 7 metres from the rear boundary, does not overbear the neighbours and avoids new overlooking. We resolve the boundary gap, privacy and daylight on the plans so the application is decided on its merits.
Frequently, yes. If the rear extension involves work to a shared wall, building up to the boundary, or excavating foundations near a neighbour's structure, the Party Wall etc. Act applies and you must serve notice — this is separate from Charnwood Borough Council's planning decision. We flag it early and can prepare the drawings a party-wall surveyor needs alongside the planning set.
We price each Charnwood rear extension on its own footprint and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Charnwood Borough Council approves, and we confirm at the outset whether your extension is permitted development, needs prior approval, or a full application.
