The fast route to a deep single-storey rear extension in Hedingham — up to 6 metres on an attached house or 8 on a detached one — via Braintree District Council's prior approval scheme rather than a full planning application.
Braintree District Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. Hedingham contains Castle Hedingham, Sible Hedingham South, Sible Hedingham West conservation areas (Castle Hedingham designated 1969), 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.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. In conservation areas such as Castle Hedingham, Sible Hedingham South and Sible Hedingham West those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Hedingham is determined against an 8-week statutory target.
Castle Hedingham (conservation area designated in 1969), Sible Hedingham South (conservation area designated in 1969), Sible Hedingham West (conservation area designated in 1969), Castle Hedingham (civil parish within Hedingham) and Sible Hedingham (civil parish within Hedingham) — these are the Hedingham pockets our drawings cover most. Heritage designations here include Castle Hedingham, Sible Hedingham South and Sible Hedingham West. Braintree District Council weighs each proposal against the adopted Braintree local plan and Braintree District Council's design guidance for householder work, where the 2,570 homes here are 18% 1965-1972, 16% pre-1900, 14% 1983-1992, 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 (18% of 2,570 homes), Victorian and earlier houses (16%) and 1980s estate houses (14%).
Before anything is drawn we check your address against the designations that apply in Hedingham: Castle Hedingham (conservation area designated in 1969), Sible Hedingham South (conservation area designated in 1969) and Sible Hedingham West (conservation area designated in 1969). Inside those boundaries permitted development is curtailed and Braintree 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, Hedingham takes in Castle Hedingham and Sible Hedingham. No Article 4 direction is recorded for Braintree District Council, but Hedingham's 3 conservation areas still limit permitted development on those streets.
On stock, Hedingham is late-1960s and early-1970s houses (18% of 2,570 homes), Victorian and earlier houses (16%) and 1980s estate houses (14%) — 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. Braintree District Council decided 431 householder applications in the latest published year and granted 92%, with 78% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Hedingham runs pre-1900 16% (420 homes), 1900-1918 2% (50 homes), 1919-1929 7% (180 homes), 1930-1939 4% (90 homes), 1945-1954 8% (210 homes), 1955-1964 3% (70 homes), 1965-1972 18% (460 homes), 1973-1982 6% (160 homes), 1983-1992 14% (350 homes), 1993-1999 3% (70 homes) and 2000-2008 6% (150 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.
Braintree District Council also decides for Bumpstead, Coggeshall, Kelvedon & Feering, Rayne, Stour Valley North, Stour Valley South, The Colnes and Three Fields, so a decision in Hedingham 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.
Published figures for Hedingham and Braintree District Council. These are the numbers that decide what is realistic on your street, so we work from them rather than from national averages.

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 Castle Hedingham and Sible Hedingham South 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.
Hedingham is largely late-1960s and early-1970s houses (18% of 2,570 homes), Victorian and earlier houses (16%) and 1980s estate houses (14%). Hedingham contains Castle Hedingham, Sible Hedingham South, Sible Hedingham West conservation areas (Castle Hedingham designated 1969), 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 Braintree District Council, but Hedingham'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 Braintree District Council instead:
We prepare the notification pack Braintree 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 Braintree District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Braintree District Council granted 92% of its householder applications in the year to 31 March 2026, and Castle Hedingham 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 Castle Hedingham, Sible Hedingham South and Sible Hedingham West, 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 2,570 homes here are 18% 1965-1972, 16% pre-1900, 14% 1983-1992, 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 Hedingham. A few of the areas where deep rear extensions come up most often:

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 Hedingham 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 Braintree 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 Braintree 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 Hedingham address specifically.
It is a notification, not an application for permission. You tell Braintree 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 Hedingham 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 Hedingham address specifically. Braintree District Council is the decision-maker.
No. The larger home extension scheme is unavailable on designated land, which includes conservation areas such as Castle Hedingham and Sible Hedingham South, 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 Braintree District 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 Hedingham address specifically. Braintree 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 Hedingham address specifically. Braintree District Council is the decision-maker.
We quote each Hedingham scheme individually, because plot shape and the boundary relationship drive the work, and send a fixed, no-obligation quote within one working day. It covers the notification pack and free revisions until Braintree District Council determines it. Call 020 7864 7245 to start.
