Back-of-house extension drawings for Aughton & Swallownest homes — the glazed kitchen-diner across the rear, drawn to Rotherham Metropolitan Borough Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Rotherham Metropolitan Borough Council granted 71% of the householder planning decisions it made in its latest published year — 16 points below the 87% England-wide householder average. Aughton & Swallownest contains the Ulley conservation area (Ulley designated 2013), 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. In conservation areas such as Ulley those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Aughton & Swallownest is determined against an 8-week statutory target.
Ulley (conservation area designated in 2013), Ulley (civil parish within Aughton & Swallownest), Aston cum Aughton (civil parish within Aughton & Swallownest) and Orgreave (civil parish within Aughton & Swallownest) — these are the Aughton & Swallownest pockets our drawings cover most. Heritage designations here include Ulley. Rotherham Metropolitan Borough Council weighs each proposal against Rotherham Metropolitan Borough Council's development plan and the design policies it applies to householder applications, where the 3,370 homes here are 15% 1965-1972, 15% 1973-1982, 14% 2000-2008, 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 shallow trussed roofs typical of 1970s building, over late-1960s and early-1970s houses (15% of 3,370 homes), 1970s and early-1980s houses (15%) and 2000s houses and apartments (14%).
Aughton & Swallownest's designated heritage is specific, and it is the first thing we check against your address: Ulley (conservation area designated in 2013). Inside those boundaries permitted development is curtailed and Rotherham Metropolitan 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, Aughton & Swallownest takes in Ulley, Aston cum Aughton and Orgreave. No Article 4 direction is recorded for Rotherham Metropolitan Borough Council, but Aughton & Swallownest's 1 conservation area still limit permitted development on those streets.
On stock, Aughton & Swallownest is late-1960s and early-1970s houses (15% of 3,370 homes), 1970s and early-1980s houses (15%) and 2000s houses and apartments (14%) — which is why shallow-pitched roofs and integral garages typical of that period's building and shallow trussed roofs typical of 1970s building govern what a loft or rear projection can realistically be. Rotherham Metropolitan Borough Council decided 402 householder applications in the latest published year and granted 71%, with 72% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Aughton & Swallownest runs pre-1900 8% (260 homes), 1900-1918 4% (150 homes), 1919-1929 2% (70 homes), 1930-1939 7% (240 homes), 1945-1954 11% (370 homes), 1955-1964 7% (240 homes), 1965-1972 15% (500 homes), 1973-1982 15% (490 homes), 1983-1992 9% (300 homes), 1993-1999 1% (50 homes) and 2000-2008 14% (460 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.
Rotherham Metropolitan Borough Council also decides for Anston & Woodsetts, Aston & Todwick, Boston Castle, Bramley & Ravenfield, Dalton & Thrybergh, Dinnington, Hoober and Keppel, so a decision in Aughton & Swallownest 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 Aughton & Swallownest 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 (15% of 3,370 homes), 1970s and early-1980s houses (15%) and 2000s houses and apartments (14%), most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Rotherham Metropolitan Borough Council scrutinises. The council reads the proposal against Rotherham Metropolitan 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. Aughton & Swallownest contains the Ulley conservation area (Ulley designated 2013), 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 — Ulley among Aughton & Swallownest's — the larger-home extension route is switched off and even a modest rear addition needs consent. No Article 4 direction is recorded for Rotherham Metropolitan Borough Council, but Aughton & Swallownest's 1 conservation area still limit permitted development on those streets. We confirm the designation before the survey.
Many single-storey rear extensions in Aughton & Swallownest are permitted development and need no application. You will normally need to apply to Rotherham Metropolitan 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 Rotherham Metropolitan 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 Rotherham Metropolitan Borough Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Rotherham Metropolitan Borough Council granted 71% of its householder applications in the year to 31 March 2026, and Ulley 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 Ulley, Ulley and Aston cum Aughton, 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 (15% of 3,370 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 3,370 homes here are 15% 1965-1972, 15% 1973-1982, 14% 2000-2008, 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 Rotherham Metropolitan 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 Aughton & Swallownest back-of-house projects come up most often:

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