The fast route to a deep single-storey rear extension in Normandy & Pirbright — up to 6 metres on an attached house or 8 on a detached one — via Guildford Borough Council's prior approval scheme rather than a full planning application.
Guildford Borough Council granted 86% of the householder planning decisions it made in its latest published year — 1 point below the 87% England-wide householder average. Normandy & Pirbright contains Basingstoke Canal North, Bisley Camp, Pirbright conservation areas (Basingstoke Canal North designated 1985), 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), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Guildford Borough Council needs a full application. In conservation areas such as Basingstoke Canal North, Bisley Camp and Pirbright those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Normandy & Pirbright is determined against an 8-week statutory target.
Basingstoke Canal North (conservation area designated in 1985), Bisley Camp (conservation area designated in 1991), Pirbright (conservation area designated in 1973), Normandy (civil parish within Normandy & Pirbright) and Pirbright (civil parish within Normandy & Pirbright) — these are the Normandy & Pirbright pockets our drawings cover most. Heritage designations here include Basingstoke Canal North, Bisley Camp and Pirbright. Guildford Borough Council weighs each proposal against Guildford Borough Council's adopted local plan and its householder design guidance, where the 2,660 homes here are 16% 1955-1964, 13% 1930-1939, 12% pre-1900, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow gabled roofs typical of that period's building and hipped roofs with shallow pitches typical of 1930s building, over late-1950s and early-1960s houses (16% of 2,660 homes), 1930s semi-detached and detached houses (13%) and Victorian and earlier houses (12%).
Heritage designation is the single biggest variable in Normandy & Pirbright, and it is address-specific: Basingstoke Canal North (conservation area designated in 1985), Bisley Camp (conservation area designated in 1991) and Pirbright (conservation area designated in 1973). Inside those boundaries permitted development is curtailed and Guildford 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, Normandy & Pirbright takes in Normandy and Pirbright. No Article 4 direction is recorded for Guildford Borough Council, but Normandy & Pirbright's 3 conservation areas still limit permitted development on those streets.
On stock, Normandy & Pirbright is late-1950s and early-1960s houses (16% of 2,660 homes), 1930s semi-detached and detached houses (13%) and Victorian and earlier houses (12%) — which is why shallow gabled roofs typical of that period's building and hipped roofs with shallow pitches typical of 1930s building govern what a loft or rear projection can realistically be. Guildford Borough Council decided 828 householder applications in the latest published year and granted 86%, with 31% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Normandy & Pirbright runs pre-1900 12% (320 homes), 1900-1918 6% (150 homes), 1919-1929 4% (100 homes), 1930-1939 13% (350 homes), 1945-1954 11% (300 homes), 1955-1964 16% (430 homes), 1965-1972 12% (310 homes), 1973-1982 4% (110 homes), 1983-1992 4% (110 homes), 1993-1999 8% (220 homes) and 2000-2008 4% (100 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.
Guildford Borough Council also decides for Ash Vale, Castle, Clandon & Horsley, Pilgrims, Send & Lovelace, Shalford, Stoke and Tillingbourne, so a decision in Normandy & Pirbright 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 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 Basingstoke Canal North and Bisley Camp 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.
Normandy & Pirbright is largely late-1950s and early-1960s houses (16% of 2,660 homes), 1930s semi-detached and detached houses (13%) and Victorian and earlier houses (12%). Normandy & Pirbright contains Basingstoke Canal North, Bisley Camp, Pirbright conservation areas (Basingstoke Canal North designated 1985), 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. No Article 4 direction is recorded for Guildford Borough Council, but Normandy & Pirbright's 3 conservation areas still limit permitted development on those streets.
The scheme is available where all of these hold. Fail any one and it is a full application to Guildford Borough Council instead:
We prepare the notification pack Guildford Borough 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 Guildford Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Guildford Borough Council granted 86% of its householder applications in the year to 31 March 2026, and Basingstoke Canal North 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 Basingstoke Canal North, Bisley Camp and Pirbright, 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 2,660 homes here are 16% 1955-1964, 13% 1930-1939, 12% pre-1900, 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 Normandy & Pirbright. A few of the areas where deep rear extensions come up most often:
Prior approval drawings for Basingstoke Canal North — conservation area designated in 1985 — dimensioned to the 6m and 8m limits and prepared for Guildford Borough Council's neighbour consultation.
Prior approval drawings for Bisley Camp — conservation area designated in 1991 — dimensioned to the 6m and 8m limits and prepared for Guildford Borough Council's neighbour consultation.
Prior approval drawings for Pirbright — conservation area designated in 1973 — dimensioned to the 6m and 8m limits and prepared for Guildford Borough Council's neighbour consultation.
Prior approval drawings for Normandy — civil parish within Normandy & Pirbright — dimensioned to the 6m and 8m limits and prepared for Guildford Borough Council's neighbour consultation.
Prior approval drawings for Pirbright — civil parish within Normandy & Pirbright — dimensioned to the 6m and 8m limits and prepared for Guildford Borough 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 Normandy & Pirbright 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 Guildford Borough 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 Guildford Borough 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 Normandy & Pirbright address specifically.
It is a notification, not an application for permission. You tell Guildford Borough 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 Normandy & Pirbright 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 Normandy & Pirbright address specifically. Guildford Borough Council is the decision-maker.
No. The larger home extension scheme is unavailable on designated land, which includes conservation areas such as Basingstoke Canal North and Bisley Camp, 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 Guildford Borough Council. This applies to your Normandy & Pirbright 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 Normandy & Pirbright address specifically. Guildford Borough 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 Normandy & Pirbright address specifically. Guildford Borough Council is the decision-maker.
We quote each Normandy & Pirbright scheme individually, because plot shape and the boundary relationship drive the work, and send a fixed, no-obligation quote within one working day.
