The fast route to a deep single-storey rear extension in St Neots Eynesbury — up to 6 metres on an attached house or 8 on a detached one — via Huntingdonshire District Council's prior approval scheme rather than a full planning application.
Huntingdonshire 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. St Neots Eynesbury contains the SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD conservation area, so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant 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. St Neots Eynesbury carries at least one Article 4 direction, and conservation areas including SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in St Neots Eynesbury is determined against an 8-week statutory target.
SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD (designated conservation area) and St. Neots (civil parish within St Neots Eynesbury) — these are the St Neots Eynesbury pockets our drawings cover most. Heritage designations here include SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD. Huntingdonshire District Council weighs each proposal against the adopted Huntingdonshire local plan and Huntingdonshire District Council's design guidance for householder work, where the 6,050 homes here are 26% 1965-1972, 18% 1983-1992, 14% 2000-2008, 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 trussed-rafter roofs typical of 1980s building, over late-1960s and early-1970s houses (26% of 6,050 homes), 1980s estate houses (18%) and 2000s houses and apartments (14%).
St Neots Eynesbury's designated heritage is specific, and it is the first thing we check against your address: SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD (designated conservation area). Inside those boundaries permitted development is curtailed and Huntingdonshire 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, St Neots Eynesbury takes in St. Neots. Huntingdonshire District Council has 6 recorded Article 4 directions, removing permitted development for painting the exterior — check the address before assuming PD applies in St Neots Eynesbury.
On stock, St Neots Eynesbury is late-1960s and early-1970s houses (26% of 6,050 homes), 1980s estate houses (18%) and 2000s houses and apartments (14%) — which is why shallow-pitched roofs and integral garages typical of that period's building and trussed-rafter roofs typical of 1980s building govern what a loft or rear projection can realistically be. Huntingdonshire District Council decided 512 householder applications in the latest published year and granted 95%, with 55% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for St Neots Eynesbury runs pre-1900 7% (420 homes), 1900-1918 1% (70 homes), 1919-1929 2% (120 homes), 1930-1939 2% (110 homes), 1945-1954 1% (90 homes), 1955-1964 9% (550 homes), 1965-1972 26% (1,560 homes), 1973-1982 3% (190 homes), 1983-1992 18% (1,070 homes), 1993-1999 6% (380 homes) and 2000-2008 14% (860 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.
Huntingdonshire District Council also decides for Alconbury, Brampton, Buckden, Fenstanton, Great Paxton, Great Staughton, Huntingdon East and Huntingdon North, so a decision in St Neots Eynesbury 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 Galley Hill, Hemingford Grey, Poultry Houses, High Bank, Hill View, Spaldwick Road, Stow Longa, Land East Of Crosshall Road, St Neots and Oundle Road, Alwalton. 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 SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD 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.
St Neots Eynesbury is largely late-1960s and early-1970s houses (26% of 6,050 homes), 1980s estate houses (18%) and 2000s houses and apartments (14%). St Neots Eynesbury contains the SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD conservation area, 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. Huntingdonshire District Council has 6 recorded Article 4 directions, removing permitted development for painting the exterior — check the address before assuming PD applies in St Neots Eynesbury.
The scheme is available where all of these hold. Fail any one and it is a full application to Huntingdonshire District Council instead:
We prepare the notification pack Huntingdonshire 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 Huntingdonshire District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Huntingdonshire District Council granted 95% of its householder applications in the year to 31 March 2026, and SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD 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 SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD and St. Neots, 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 6,050 homes here are 26% 1965-1972, 18% 1983-1992, 14% 2000-2008, 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 St Neots Eynesbury. A few of the areas where deep rear extensions come up most often:
Prior approval drawings for SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD — designated conservation area — dimensioned to the 6m and 8m limits and prepared for Huntingdonshire District Council's neighbour consultation.
Prior approval drawings for St. Neots — civil parish within St Neots Eynesbury — dimensioned to the 6m and 8m limits and prepared for Huntingdonshire 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 St Neots Eynesbury 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 Huntingdonshire 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 Huntingdonshire 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 St Neots Eynesbury address specifically.
It is a notification, not an application for permission. You tell Huntingdonshire 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 St Neots Eynesbury 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 St Neots Eynesbury address specifically. Huntingdonshire District Council is the decision-maker.
No. The larger home extension scheme is unavailable on designated land, which includes conservation areas such as SAINT NEOTS INCL EYNESBURY AND EATON SOCON AND EATON FORD, 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 Huntingdonshire District Council. This applies to your St Neots Eynesbury 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 St Neots Eynesbury address specifically. Huntingdonshire 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 St Neots Eynesbury address specifically. Huntingdonshire District Council is the decision-maker.
