Back-of-house extension drawings for Barlborough homes — the glazed kitchen-diner across the rear, drawn to Bolsover District Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Bolsover District Council granted 98% of the householder planning decisions it made in its latest published year — 11 points above the 87% England-wide householder average. Barlborough contains the Barlborough conservation area (Barlborough designated 1972), 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) and interwar (1918–1939) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. In conservation areas such as Barlborough those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Barlborough is determined against an 8-week statutory target.
Barlborough (conservation area designated in 1972) and Clowne (civil parish within Barlborough) — these are the Barlborough pockets our drawings cover most. Heritage designations here include Barlborough. Bolsover District Council weighs each proposal against Bolsover District Council's adopted local plan and its householder design guidance, where the 1,520 homes here are 33% 1993-1999, 11% 1930-1939, 9% pre-1900, which is what sets the realistic roof and rear-projection options. On roofs the borough is trussed-rafter roofs typical of 1990s building and hipped roofs with shallow pitches typical of 1930s building, over 1990s estate houses (33% of 1,520 homes), 1930s semi-detached and detached houses (11%) and Victorian and earlier houses (9%).
What is permitted in Barlborough turns on designation first, so that is where we start: Barlborough (conservation area designated in 1972). Inside those boundaries permitted development is curtailed and Bolsover District 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, Barlborough takes in Clowne. No Article 4 direction is recorded for Bolsover District Council, but Barlborough's 1 conservation area still limit permitted development on those streets.
On stock, Barlborough is 1990s estate houses (33% of 1,520 homes), 1930s semi-detached and detached houses (11%) and Victorian and earlier houses (9%) — which is why trussed-rafter roofs typical of 1990s building and hipped roofs with shallow pitches typical of 1930s building govern what a loft or rear projection can realistically be. Bolsover District Council decided 130 householder applications in the latest published year and granted 98%, with 77% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Barlborough runs pre-1900 9% (140 homes), 1900-1918 3% (50 homes), 1919-1929 2% (30 homes), 1930-1939 11% (170 homes), 1945-1954 7% (110 homes), 1955-1964 3% (50 homes), 1965-1972 7% (100 homes), 1973-1982 7% (110 homes), 1983-1992 2% (30 homes), 1993-1999 33% (500 homes) and 2000-2008 4% (60 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.
Bolsover District Council also decides for Ault Hucknall, Blackwell, Bolsover East, Bolsover South, Clowne East, Elmton-with-Creswell, Langwith and Shirebrook South, so a decision in Barlborough 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 Barlborough home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from 1990s estate houses (33% of 1,520 homes), 1930s semi-detached and detached houses (11%) and Victorian and earlier houses (9%), most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Bolsover District Council scrutinises. The council reads the proposal against Bolsover District Council's adopted local plan and its householder design guidance, 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. Barlborough contains the Barlborough conservation area (Barlborough designated 1972), 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 — Barlborough among Barlborough's — the larger-home extension route is switched off and even a modest rear addition needs consent. No Article 4 direction is recorded for Bolsover District Council, but Barlborough's 1 conservation area still limit permitted development on those streets. We confirm the designation before the survey.
Many single-storey rear extensions in Barlborough are permitted development and need no application. You will normally need to apply to Bolsover District 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 Bolsover District 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 Bolsover District Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Bolsover District Council granted 98% of its householder applications in the year to 31 March 2026, and Barlborough shapes what is approved here. 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 Barlborough and Clowne, 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 1990s estate houses (33% of 1,520 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 1,520 homes here are 33% 1993-1999, 11% 1930-1939, 9% pre-1900, 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 Bolsover District 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 Barlborough back-of-house projects come up most often:
Rear extension drawings for Barlborough's conservation area designated in 1972 — depth-checked, daylight-tested and drawn to Bolsover District Council's guidance.
Rear extension drawings for Clowne's civil parish within Barlborough — depth-checked, daylight-tested and drawn to Bolsover District Council's guidance.
How far you can extend at the back in Barlborough depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Bolsover District 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 Barlborough and Article 4 streets need a full application.
A fixed process built around how Bolsover District Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Barlborough 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 Bolsover District 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 Bolsover District 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 Bolsover District 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 Barlborough. You will need to involve Bolsover District 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 Barlborough, 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 Bolsover District 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 Barlborough's conservation areas.
It is the daylight test Bolsover District 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. This applies to your Barlborough address specifically.
A two-storey rear extension almost always needs a full householder application to Bolsover District 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. This applies to your Barlborough address specifically.
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 Bolsover District Council's planning decision. We flag it early and can prepare the drawings a party-wall surveyor needs alongside the planning set. This applies to your Barlborough address specifically.
We price each Barlborough 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 Bolsover District Council approves, and we confirm at the outset whether your extension is permitted development, needs prior approval, or a full application.
