The fast route to a deep single-storey rear extension in Stoke, Plymouth — up to 6 metres on an attached house or 8 on a detached one — via Plymouth City Council's prior approval scheme rather than a full planning application.
Plymouth City Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Stoke's spacious, tree-lined Victorian villa streets are protected for their leafy character, capping bulk and hard-surfacing on the larger plots, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901), Edwardian (1901–1910) and interwar (1918–1939) 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 Stoke and Devonport those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Stoke, Plymouth is determined against an 8-week statutory target.
Stoke Village (the leafy conservation-area heart of Victorian and Georgian villas), Devonport Road (tree-lined avenue of substantial period houses), Wingfield Villas (grand mid-Victorian detached villas set in generous plots), Albert Road (Victorian terraces running down toward the dockyard gate), Penlee (elevated Edwardian and interwar streets above Stoke) and Stoke Damerel (the ancient parish edge shared with Devonport) — these are the Stoke, Plymouth pockets our drawings cover most. Heritage designations here include Stoke and Devonport. Plymouth City Council weighs each proposal against the Plymouth and South West Devon Joint Local Plan (2019), where the conservation area's grander detached houses are assessed in fine grain, down to boundary walls, railings and original fenestration. Several of Stoke's larger villas have been subdivided into flats and maisonettes, which do not carry householder permitted-development rights.. On roofs the borough is pitched and gabled slate roofs on the Victorian villas and hipped roofs on the Edwardian and interwar semis, over Victorian and Georgian villas along Devonport Road, Edwardian and interwar semi-detached houses and converted flats in the larger period 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 Stoke and Devonport 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.
Stoke, Plymouth is largely Victorian and Georgian villas along Devonport Road, Edwardian and interwar semi-detached houses and converted flats in the larger period villas. Stoke's spacious, tree-lined Victorian villa streets are protected for their leafy character, capping bulk and hard-surfacing on the larger plots, which matters here because an objecting neighbour puts amenity squarely in front of a case officer. Stoke sits outside the city's HMO Article 4 area (which covers Mutley, Greenbank and the city centre), so a small shared-house conversion may still be permitted development here, but alterations within the Stoke and adjoining Devonport conservation areas require planning consent.
The scheme is available where all of these hold. Fail any one and it is a full application to Plymouth City Council instead:
We prepare the notification pack Plymouth 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 Plymouth City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Plymouth grants the large majority of householder applications in Stoke, where the leafy villa character and the conservation-area detailing, rather than site density, set the limits on how far extensions and roof changes can go. Prior approval turns on neighbour amenity alone, so the drawings that matter are the ones showing the relationship to the boundary.

Across Stoke Village, Devonport Road and Wingfield Villas, 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 conservation area's grander detached houses are assessed in fine grain, down to boundary walls, railings and original fenestration. 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 Stoke, Plymouth. A few of the areas where deep rear extensions come up most often:
Prior approval drawings for Stoke Village — the leafy conservation-area heart of Victorian and Georgian villas — dimensioned to the 6m and 8m limits and prepared for Plymouth City Council's neighbour consultation.
Prior approval drawings for Devonport Road — tree-lined avenue of substantial period houses — dimensioned to the 6m and 8m limits and prepared for Plymouth City Council's neighbour consultation.
Prior approval drawings for Wingfield Villas — grand mid-Victorian detached villas set in generous plots — dimensioned to the 6m and 8m limits and prepared for Plymouth City Council's neighbour consultation.
Prior approval drawings for Albert Road — Victorian terraces running down toward the dockyard gate — dimensioned to the 6m and 8m limits and prepared for Plymouth City Council's neighbour consultation.
Prior approval drawings for Penlee — elevated Edwardian and interwar streets above Stoke — dimensioned to the 6m and 8m limits and prepared for Plymouth City Council's neighbour consultation.
Prior approval drawings for Stoke Damerel — the ancient parish edge shared with Devonport — dimensioned to the 6m and 8m limits and prepared for Plymouth 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 Stoke, Plymouth 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 Plymouth 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 Plymouth 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 Stoke, Plymouth address specifically.
It is a notification, not an application for permission. You tell Plymouth 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 Stoke, Plymouth 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 Stoke, Plymouth address specifically. Plymouth City Council is the decision-maker.
No. The larger home extension scheme is unavailable on designated land, which includes conservation areas such as Stoke and Devonport, 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 Plymouth City Council. This applies to your Stoke, Plymouth 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 Stoke, Plymouth address specifically. Plymouth 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 Stoke, Plymouth address specifically. Plymouth City Council is the decision-maker.
