Back-of-house extension drawings for Hoober 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. Hoober contains Barrow, Wentworth conservation areas (Barrow designated 1979), 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 postwar (1945–1970) 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 Barrow and Wentworth those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Hoober is determined against an 8-week statutory target.
Barrow (conservation area designated in 1979), Wentworth (designated conservation area), Brampton Bierlow (civil parish within Hoober) and Wentworth (civil parish within Hoober) — these are the Hoober pockets our drawings cover most. Heritage designations here include Barrow and Wentworth. Rotherham Metropolitan Borough Council weighs each proposal against Rotherham Metropolitan Borough Council's adopted local plan and its householder design guidance, where the 4,930 homes here are 15% 1945-1954, 15% pre-1900, 14% 2000-2008, which is what sets the realistic roof and rear-projection options. On roofs the borough is simple gabled and hipped roofs typical of early postwar building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, over early postwar houses (15% of 4,930 homes), Victorian and earlier houses (15%) and 2000s houses and apartments (14%).
What is permitted in Hoober turns on designation first, so that is where we start: Barrow (conservation area designated in 1979) and Wentworth (designated conservation area). 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, Hoober takes in Brampton Bierlow and Wentworth. No Article 4 direction is recorded for Rotherham Metropolitan Borough Council, but Hoober's 2 conservation areas still limit permitted development on those streets.
On stock, Hoober is early postwar houses (15% of 4,930 homes), Victorian and earlier houses (15%) and 2000s houses and apartments (14%) — which is why simple gabled and hipped roofs typical of early postwar 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. Rotherham Metropolitan Borough Council decided 402 householder applications in the latest published year and granted 71%, with 72% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Hoober runs pre-1900 15% (730 homes), 1900-1918 7% (330 homes), 1919-1929 13% (640 homes), 1930-1939 4% (180 homes), 1945-1954 15% (760 homes), 1955-1964 5% (230 homes), 1965-1972 5% (230 homes), 1973-1982 8% (380 homes), 1983-1992 3% (130 homes), 1993-1999 4% (180 homes) and 2000-2008 14% (690 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, Aughton & Swallownest, Boston Castle, Bramley & Ravenfield, Dalton & Thrybergh, Dinnington and Keppel, so a decision in Hoober 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 Hoober home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from early postwar houses (15% of 4,930 homes), Victorian and earlier 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 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. Hoober contains Barrow, Wentworth conservation areas (Barrow designated 1979), 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 — Barrow and Wentworth among Hoober'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 Hoober's 2 conservation areas still limit permitted development on those streets. We confirm the designation before the survey.
Many single-storey rear extensions in Hoober 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 Barrow 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 Barrow, Wentworth and Brampton Bierlow, 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 early postwar houses (15% of 4,930 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 4,930 homes here are 15% 1945-1954, 15% pre-1900, 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 Hoober back-of-house projects come up most often:

How far you can extend at the back in Hoober 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 Barrow and Wentworth 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 Hoober 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 Hoober. 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 Barrow and Wentworth, 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 Hoober'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 Hoober 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 Hoober 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 Hoober address specifically.
We price each Hoober 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 Rotherham Metropolitan Borough Council approves, and we confirm at the outset whether your extension is permitted development, needs prior approval, or a full application.
