The fast route to a deep single-storey rear extension in Rockland — up to 6 metres on an attached house or 8 on a detached one — via South Norfolk District Council's prior approval scheme rather than a full planning application.
South Norfolk District Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. Rockland contains the Bramerton Conservation Area conservation area (Bramerton Conservation Area designated 1975), 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.
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. Rockland carries at least one Article 4 direction, and conservation areas including Bramerton Conservation Area remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Rockland is determined against an 8-week statutory target.
Bramerton (conservation area designated in 1975), Rockland St. Mary (civil parish within Rockland), Carleton St. Peter (civil parish within Rockland), Claxton (civil parish within Rockland), Hellington (civil parish within Rockland), Holverston (civil parish within Rockland) and Kirby Bedon (civil parish within Rockland) — these are the Rockland pockets our drawings cover most. Heritage designations here include Bramerton Conservation Area. South Norfolk District Council weighs each proposal against South Norfolk District Council's adopted local plan and its householder design guidance, where the 1,340 homes here are 22% 1965-1972, 19% pre-1900, 10% 1993-1999, 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 (22% of 1,340 homes), Victorian and earlier houses (19%) and 1990s estate houses (10%).
Rockland's designated heritage is specific, and it is the first thing we check against your address: Bramerton (conservation area designated in 1975). Inside those boundaries permitted development is curtailed and South Norfolk 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, Rockland takes in Rockland St. Mary, Carleton St. Peter, Claxton, Hellington, Holverston and Kirby Bedon. South Norfolk District Council has 55 recorded Article 4 directions — check the address before assuming PD applies in Rockland.
On stock, Rockland is late-1960s and early-1970s houses (22% of 1,340 homes), Victorian and earlier houses (19%) and 1990s estate houses (10%) — 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. South Norfolk District Council decided 490 householder applications in the latest published year and granted 95%, with 67% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Rockland runs pre-1900 19% (250 homes), 1900-1918 1% (10 homes), 1919-1929 2% (30 homes), 1930-1939 6% (80 homes), 1945-1954 4% (60 homes), 1955-1964 9% (120 homes), 1965-1972 22% (290 homes), 1973-1982 7% (90 homes), 1983-1992 8% (110 homes), 1993-1999 10% (130 homes) and 2000-2008 4% (50 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.
South Norfolk District Council also decides for Bressingham & Burston, Brooke, Central Wymondham, Cringleford, Diss & Roydon, Forncett, Hempnall and Hethersett, so a decision in Rockland 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 1,2 Everest Place, 1-12 St Ethelberts Close, 1-12 Woodyard Square and 1-13 Smiths Knoll. 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 ordinary Class A limits stop a single-storey rear extension at 3 metres on an attached house and 4 on a detached one. The larger home extension scheme doubles both, on condition that the council is told first. That notification is not an application for permission — the council cannot refuse on design, materials or policy grounds. It can only consider the effect on the amenity of adjoining premises, and only if a neighbour actually objects during the 21-day consultation.
The other conditions still apply and are strict: single storey only, no higher than 4 metres, eaves no higher than the existing eaves, and no more than half the land around the original house covered. It is not available on designated land, so a house in a conservation area such as Bramerton Conservation Area cannot use it at all. Materials must be similar to the existing house, and the extension must not include a veranda, balcony or raised platform.
Rockland is largely late-1960s and early-1970s houses (22% of 1,340 homes), Victorian and earlier houses (19%) and 1990s estate houses (10%). Rockland contains the Bramerton Conservation Area conservation area (Bramerton Conservation Area designated 1975), so materials, fenestration and roof form are assessed against the appraisal, which matters here because an objecting neighbour puts amenity squarely in front of a case officer. South Norfolk District Council has 55 recorded Article 4 directions — check the address before assuming PD applies in Rockland.
The scheme is available where all of these hold. Fail any one and it is a full application to South Norfolk District Council instead:
We prepare the notification pack South Norfolk District Council needs — plans, elevations, a site plan with the adjoining owners identified — and manage the 21-day neighbour consultation so the 42-day clock is not restarted by an incomplete submission.
Below is South Norfolk District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. South Norfolk District Council granted 95% of its householder applications in the year to 31 March 2026, and Bramerton Conservation Area shapes what is approved here. Prior approval turns on neighbour amenity alone, so the drawings that matter are the ones showing the relationship to the boundary.

Across Bramerton, Rockland St. Mary and Carleton St. Peter, the notifications that clear without objection are the ones that treat the neighbour as the audience. We show the extension in section against the boundary, demonstrate the 45-degree daylight relationship to the nearest habitable window, and where the plot is tight we taper the depth away from the boundary rather than running the full 6 metres to the fence.
The 1,340 homes here are 22% 1965-1972, 19% pre-1900, 10% 1993-1999, which is what sets the realistic roof and rear-projection options. Where an objection does arrive, the council's assessment is narrow: loss of light, outlook and overbearing effect on the adjoining property, nothing else. A pack that has already answered those three points on the drawings usually survives an objection, whereas one that leaves them to the officer's imagination usually does not.
We prepare prior-approval notifications across Rockland. A few of the areas where deep rear extensions come up most often:
Prior approval drawings for Bramerton — conservation area designated in 1975 — dimensioned to the 6m and 8m limits and prepared for South Norfolk District Council's neighbour consultation.
Prior approval drawings for Rockland St. Mary — civil parish within Rockland — dimensioned to the 6m and 8m limits and prepared for South Norfolk District Council's neighbour consultation.
Prior approval drawings for Carleton St. Peter — civil parish within Rockland — dimensioned to the 6m and 8m limits and prepared for South Norfolk District Council's neighbour consultation.
Prior approval drawings for Claxton — civil parish within Rockland — dimensioned to the 6m and 8m limits and prepared for South Norfolk District Council's neighbour consultation.
Prior approval drawings for Hellington — civil parish within Rockland — dimensioned to the 6m and 8m limits and prepared for South Norfolk District Council's neighbour consultation.
Prior approval drawings for Holverston — civil parish within Rockland — dimensioned to the 6m and 8m limits and prepared for South Norfolk District Council's neighbour consultation.
Same extension, two routes, very different tests.
| Route | Depth allowed | What the council may consider | Timescale |
|---|---|---|---|
| Ordinary Class A permitted development | 3m attached / 4m detached | Nothing — no application needed | Immediate |
| Larger home extension prior approval | 6m attached / 8m detached | Amenity of adjoining premises, only if a neighbour objects | 21-day consultation, 42-day determination |
| Full householder application | No fixed limit | Design, materials, policy, amenity, everything | 8-week target |
| Any of these on designated land | 3m / 4m only | Prior approval scheme unavailable | Full application beyond the limits |
Limits and procedure from the GPDO 2015, Schedule 2, Part 1, Class A and paragraph A.4, made permanent by amendment in 2019.
A process built around the 21-day consultation, which is where these schemes are won or lost.
Send us your Rockland postcode and house type. We confirm whether the property is on designated land, whether the scheme is available, and what depth you can realistically take.
We measure the original rear wall, eaves height, boundary distances and the neighbouring windows that the amenity assessment will turn on.
We draw the extension to the 6m or 8m limit with the boundary relationship shown in section, and prepare the written description and adjoining-owner details South Norfolk District Council needs to start the consultation.
We submit, track the 21-day consultation and the 42-day determination, respond to any objection on amenity grounds, and revise free until the decision.
Three metres on a terraced or semi-detached house and four on a detached one under ordinary permitted development. Under the larger home extension prior approval scheme those double to six and eight metres, provided you notify South Norfolk District Council before starting and the conditions on height, materials and land coverage are met. The scheme is not available on designated land. This applies to your Rockland address specifically.
It is a notification, not an application for permission. You tell South Norfolk District Council what you intend to build, it writes to the adjoining owners, and they have 21 days to object. If nobody objects, you may build. If someone does, the council assesses the effect on the amenity of adjoining premises and must decide within 42 days. Design and policy are not in scope. This applies to your Rockland address specifically.
The council then considers the impact on the amenity of the adjoining property — loss of light, loss of outlook, and overbearing effect — and nothing else. It cannot refuse because it dislikes the design or the materials. We prepare the drawings so those three questions are already answered in section and on the site plan, which is what usually carries an objected scheme through. This applies to your Rockland address specifically. South Norfolk District Council is the decision-maker.
No. The larger home extension scheme is unavailable on designated land, which includes conservation areas such as Bramerton Conservation Area, national landscapes, national parks and world heritage sites. On those properties the ordinary 3-metre and 4-metre limits apply, and anything deeper needs a full householder application to South Norfolk District Council. This applies to your Rockland address specifically.
Twenty-one days for the neighbour consultation, and a maximum of 42 days from a valid submission for the council to determine it. If the council does not respond within 42 days you may proceed as notified. That deadline is the scheme's real advantage over a full application, and it is why validation completeness matters so much. This applies to your Rockland address specifically. South Norfolk District Council is the decision-maker.
Yes — always. Prior approval deals only with the planning position. A 6-metre rear extension still needs building control approval for foundations, structure, drainage, thermal performance and fire safety, and the beam over the opening into the existing house needs designing and calculating. We prepare both sets so the notified scheme is the buildable one. This applies to your Rockland address specifically. South Norfolk District Council is the decision-maker.
