Back-of-house extension drawings for Broughton & Scawby homes — the glazed kitchen-diner across the rear, drawn to North Lincolnshire Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
North Lincolnshire Council granted 91% of the householder planning decisions it made in its latest published year — 4 points above the 87% England-wide householder average. Broughton & Scawby contains the Scawby Conservation area conservation area (Scawby Conservation area designated 1985), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant postwar (1945–1970) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. Broughton & Scawby carries at least one Article 4 direction, and conservation areas including Scawby Conservation area remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Broughton & Scawby is determined against an 8-week statutory target.
Scawby (conservation area designated in 1985), Broughton (civil parish within Broughton & Scawby) and Scawby (civil parish within Broughton & Scawby) — these are the Broughton & Scawby pockets our drawings cover most. Heritage designations here include Scawby Conservation area. North Lincolnshire Council weighs each proposal against North Lincolnshire Council's adopted local plan and its householder design guidance, where the 2,850 homes here are 17% 1973-1982, 14% 1955-1964, 13% 1965-1972, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow trussed roofs typical of 1970s building and shallow gabled roofs typical of that period's building, over 1970s and early-1980s houses (17% of 2,850 homes), late-1950s and early-1960s houses (14%) and late-1960s and early-1970s houses (13%).
Broughton & Scawby's designated heritage is specific, and it is the first thing we check against your address: Scawby (conservation area designated in 1985). Inside those boundaries permitted development is curtailed and North Lincolnshire 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, Broughton & Scawby takes in Broughton and Scawby. North Lincolnshire Council has 12 recorded Article 4 directions, removing permitted development for rear and side extensions and roof enlargements such as dormers — check the address before assuming PD applies in Broughton & Scawby.
On stock, Broughton & Scawby is 1970s and early-1980s houses (17% of 2,850 homes), late-1950s and early-1960s houses (14%) and late-1960s and early-1970s houses (13%) — which is why shallow trussed roofs typical of 1970s building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. North Lincolnshire Council decided 338 householder applications in the latest published year and granted 91%, with 70% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Broughton & Scawby runs pre-1900 6% (160 homes), 1900-1918 4% (100 homes), 1919-1929 5% (130 homes), 1930-1939 8% (240 homes), 1945-1954 8% (230 homes), 1955-1964 14% (390 homes), 1965-1972 13% (360 homes), 1973-1982 17% (490 homes), 1983-1992 8% (220 homes), 1993-1999 12% (340 homes) and 2000-2008 4% (100 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.
North Lincolnshire Council also decides for Axholme Central, Axholme North, Brigg & Wolds, Ferry and Ridge, so a decision in Broughton & Scawby 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 Article 4 directions recorded for this council include Alkborough & Walcot, Appleby, Barrow upon Humber and Barton upon Humber. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

The rear extension is the workhorse of Broughton & Scawby home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from 1970s and early-1980s houses (17% of 2,850 homes), late-1950s and early-1960s houses (14%) and late-1960s and early-1970s houses (13%), most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what North Lincolnshire Council scrutinises. The council reads the proposal against North Lincolnshire 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. Broughton & Scawby contains the Scawby Conservation area conservation area (Scawby Conservation area designated 1985), 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 — Scawby Conservation area among Broughton & Scawby's — the larger-home extension route is switched off and even a modest rear addition needs consent. North Lincolnshire Council has 12 recorded Article 4 directions, removing permitted development for rear and side extensions and roof enlargements such as dormers — check the address before assuming PD applies in Broughton & Scawby. We confirm the designation before the survey.
Many single-storey rear extensions in Broughton & Scawby are permitted development and need no application. You will normally need to apply to North Lincolnshire 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 North Lincolnshire 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 North Lincolnshire Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. North Lincolnshire Council granted 91% of its householder applications in the year to 31 March 2026, and Scawby Conservation area 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 Scawby, Broughton and Scawby, 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 1970s and early-1980s houses (17% of 2,850 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 2,850 homes here are 17% 1973-1982, 14% 1955-1964, 13% 1965-1972, 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 North Lincolnshire 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.

How far you can extend at the back in Broughton & Scawby depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What North Lincolnshire 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 Scawby Conservation area and Article 4 streets need a full application.
A fixed process built around how North Lincolnshire Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Broughton & Scawby 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 North Lincolnshire 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 North Lincolnshire 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 North Lincolnshire 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 Broughton & Scawby. You will need to involve North Lincolnshire 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 Scawby Conservation area, 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 North Lincolnshire 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 Broughton & Scawby's conservation areas.
It is the daylight test North Lincolnshire 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 Broughton & Scawby address specifically.
A two-storey rear extension almost always needs a full householder application to North Lincolnshire 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 Broughton & Scawby 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 North Lincolnshire 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 Broughton & Scawby address specifically.
