The fast route to a deep single-storey rear extension in Rottingdean — up to 6 metres on an attached house or 8 on a detached one — via Brighton & Hove City Council's prior approval scheme rather than a full planning application.
Brighton & Hove City Council granted 89% of the householder planning decisions it made in its latest published year — 2 points above the 87% England-wide householder average. The flint-and-brick village core and green at Rottingdean are protected against alterations and materials that would erode the vernacular character, which is where a policy-literate drawing pack earns its keep. Its dominant interwar (1918–1939) 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. Rottingdean carries at least one Article 4 direction, and conservation areas including Rottingdean and Ovingdean remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Rottingdean is determined against an 8-week statutory target.
Rottingdean village (the flint High Street and green around St Margaret's church and the pond), Ovingdean (the smaller downland village around St Wulfran's church), Rottingdean seafront (clifftop houses along the undercliff and Marine Drive), Nevill estate (interwar and postwar semis climbing the western slope), Saltdean fringe (1930s seaside bungalows and semis toward the Lido) and Woodingdean edge (postwar downland-fringe housing above the village) — these are the Rottingdean pockets our drawings cover most. Heritage designations here include Rottingdean and Ovingdean. Brighton & Hove City Council weighs each proposal against Brighton & Hove City Plan (Parts One 2016 and Two 2022) and the relevant SPDs, where the northern edges of the village abut the South Downs National Park, where development on the open downland fringe is tightly restrained. Some of the larger village and seafront houses have been converted into flats, which carry no householder permitted-development rights.. On roofs the borough is pitched clay-tiled and slate roofs on the village houses and hipped roofs on the interwar semis and bungalows, over historic flint and brick village cottages, interwar and postwar seaside semis and bungalows and detached downland villas.
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 Rottingdean and Ovingdean 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.
Rottingdean is largely historic flint and brick village cottages, interwar and postwar seaside semis and bungalows and detached downland villas. The flint-and-brick village core and green at Rottingdean are protected against alterations and materials that would erode the vernacular character, which matters here because an objecting neighbour puts amenity squarely in front of a case officer. Rottingdean falls under the city-wide small-HMO Article 4 direction, and the Rottingdean conservation area — one of the historic downland villages designated in 1970 — adds Article 4 controls protecting its flint-and-brick village core.
The scheme is available where all of these hold. Fail any one and it is a full application to Brighton & Hove City Council instead:
We prepare the notification pack Brighton & Hove City 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 Brighton & Hove City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Brighton & Hove approves most householder work, and in Rottingdean the deciding factors are the protected village character and the sensitive downland and coastal setting rather than the principle of extending. Prior approval turns on neighbour amenity alone, so the drawings that matter are the ones showing the relationship to the boundary.

Across Rottingdean village, Ovingdean and Rottingdean seafront, 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 northern edges of the village abut the South Downs National Park, where development on the open downland fringe is tightly restrained. 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 Rottingdean. A few of the areas where deep rear extensions come up most often:
Prior approval drawings for Rottingdean village — the flint High Street and green around St Margaret's church and the pond — dimensioned to the 6m and 8m limits and prepared for Brighton & Hove City Council's neighbour consultation.
Prior approval drawings for Ovingdean — the smaller downland village around St Wulfran's church — dimensioned to the 6m and 8m limits and prepared for Brighton & Hove City Council's neighbour consultation.
Prior approval drawings for Rottingdean seafront — clifftop houses along the undercliff and Marine Drive — dimensioned to the 6m and 8m limits and prepared for Brighton & Hove City Council's neighbour consultation.
Prior approval drawings for Nevill estate — interwar and postwar semis climbing the western slope — dimensioned to the 6m and 8m limits and prepared for Brighton & Hove City Council's neighbour consultation.
Prior approval drawings for Saltdean fringe — 1930s seaside bungalows and semis toward the Lido — dimensioned to the 6m and 8m limits and prepared for Brighton & Hove City Council's neighbour consultation.
Prior approval drawings for Woodingdean edge — postwar downland-fringe housing above the village — dimensioned to the 6m and 8m limits and prepared for Brighton & Hove City 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 Rottingdean 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 Brighton & Hove City 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 Brighton & Hove City 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 Rottingdean address specifically.
It is a notification, not an application for permission. You tell Brighton & Hove City 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 Rottingdean 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 Rottingdean address specifically. Brighton & Hove City Council is the decision-maker.
No. The larger home extension scheme is unavailable on designated land, which includes conservation areas such as Rottingdean and Ovingdean, 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 Brighton & Hove City Council.
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 Rottingdean address specifically. Brighton & Hove City 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 Rottingdean address specifically. Brighton & Hove City Council is the decision-maker.
We quote each Rottingdean scheme individually, because plot shape and the boundary relationship drive the work, and send a fixed, no-obligation quote within one working day.
