Back-of-house extension drawings for Stour Valley North homes — the glazed kitchen-diner across the rear, drawn to Braintree District Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
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. Stour Valley North contains Ashen, Belchamp Otten, Belchamp St Paul conservation areas (Ashen designated 1989), 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.
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 Ashen, Belchamp Otten and Belchamp St Paul those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Stour Valley North is determined against an 8-week statutory target.
Ashen (conservation area designated in 1989), Belchamp Otten (conservation area designated in 1984), Belchamp St Paul (conservation area designated in 1979), Belchamp Walter (conservation area designated in 1980), Foxearth (conservation area designated in 1976), Ridgewell (conservation area designated in 1973), Borley (civil parish within Stour Valley North), Foxearth (civil parish within Stour Valley North), Ashen (civil parish within Stour Valley North), Belchamp Otten (civil parish within Stour Valley North), Belchamp St. Paul (civil parish within Stour Valley North) and Belchamp Walter (civil parish within Stour Valley North) — these are the Stour Valley North pockets our drawings cover most. Heritage designations here include Ashen, Belchamp Otten, Belchamp St Paul, Belchamp Walter, Foxearth and Ridgewell. Braintree District Council weighs each proposal against the adopted Braintree local plan and Braintree District Council's design guidance for householder work, where the 2,050 homes here are 39% pre-1900, 10% 1965-1972, 7% 1930-1939, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow-pitched roofs and integral garages typical of that period's building, over Victorian and earlier houses (39% of 2,050 homes), late-1960s and early-1970s houses (10%) and 1930s semi-detached and detached houses (7%).
Before anything is drawn we check your address against the designations that apply in Stour Valley North: Ashen (conservation area designated in 1989), Belchamp Otten (conservation area designated in 1984), Belchamp St Paul (conservation area designated in 1979), Belchamp Walter (conservation area designated in 1980), Foxearth (conservation area designated in 1976) and Ridgewell (conservation area designated in 1973). 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, Stour Valley North takes in Borley, Foxearth, Ashen, Belchamp Otten, Belchamp St. Paul and Belchamp Walter. No Article 4 direction is recorded for Braintree District Council, but Stour Valley North's 6 conservation areas still limit permitted development on those streets.
On stock, Stour Valley North is Victorian and earlier houses (39% of 2,050 homes), late-1960s and early-1970s houses (10%) and 1930s semi-detached and detached houses (7%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow-pitched roofs and integral garages typical of that period's 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 Stour Valley North runs pre-1900 39% (790 homes), 1900-1918 2% (40 homes), 1919-1929 2% (40 homes), 1930-1939 7% (150 homes), 1945-1954 5% (100 homes), 1955-1964 5% (110 homes), 1965-1972 10% (210 homes), 1973-1982 6% (120 homes), 1983-1992 6% (130 homes), 1993-1999 6% (130 homes) and 2000-2008 3% (70 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, Hedingham, Kelvedon & Feering, Rayne, Stour Valley South, The Colnes and Three Fields, so a decision in Stour Valley North 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 rear extension is the workhorse of Stour Valley North home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from Victorian and earlier houses (39% of 2,050 homes), late-1960s and early-1970s houses (10%) and 1930s semi-detached and detached houses (7%), most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Braintree District Council scrutinises. The council reads the proposal against the adopted Braintree local plan and Braintree District Council's design guidance for householder work, and the first line an officer draws is the 45-degree splay from the neighbour's nearest window.
So the drawings live or die on geometry. We set the depth against the exact permitted-development figure, hold the eaves and the flat-roof or lantern build-up under the 4-metre height ceiling, and show the projection tested against both the 45-degree plan angle and the 25-degree section angle to the neighbouring windows. Stour Valley North contains Ashen, Belchamp Otten, Belchamp St Paul conservation areas (Ashen designated 1989), so materials, fenestration and roof form are assessed against the appraisal, so the rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — Ashen, Belchamp Otten, Belchamp St Paul, Belchamp Walter, Foxearth and Ridgewell among Stour Valley North's — the larger-home extension route is switched off and even a modest rear addition needs consent. No Article 4 direction is recorded for Braintree District Council, but Stour Valley North's 6 conservation areas still limit permitted development on those streets. We confirm the designation before the survey.
Many single-storey rear extensions in Stour Valley North are permitted development and need no application. You will normally need to apply to Braintree District Council, or use the larger-home prior-approval route, if any of these apply:
We draw the depth, the roof build-up and the daylight splays to each neighbour on the page — the tests Braintree District Council's officers apply first — and submit a validation-complete pack, whether that is a lawful development certificate, a larger-home prior-approval notice or a full householder application.
Below is Braintree District Council's real householder decision record, taken 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 Ashen shapes what is approved here. Rear extensions turn most often on neighbour daylight and depth, so a drawing pack that proves those tests upfront is decided faster and refused less often than a DIY submission.

Across Ashen, Belchamp Otten and Belchamp St Paul, the approved rear extension is typically a single-storey glazed box within the depth limit, roofed either flat with a lantern or in a shallow mono-pitch, and finished in brick or render to match the host wall. On the borough's victorian and earlier houses (39% of 2,050 homes), keeping the projection to the permitted-development figure often avoids an application entirely; where owners want the full 6 metres, the larger-home route succeeds when the neighbour-consultation period passes without a sustained objection.
The 2,050 homes here are 39% pre-1900, 10% 1965-1972, 7% 1930-1939, which is what sets the realistic roof and rear-projection options. We keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Braintree District Council expects — so the back elevation answers the amenity case before a neighbour can lodge one. Two-storey rear extensions we draw with the 7-metre boundary gap and privacy screening resolved on the plan.
We draw rear extensions on every street in the borough. A few of the neighbourhoods where Stour Valley North back-of-house projects come up most often:

How far you can extend at the back in Stour Valley North depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Braintree District Council checks |
|---|---|---|---|
| Standard permitted development | 3m terrace/semi · 4m detached | Lawful development certificate (optional) | Depth, 4m height, materials |
| Larger-home prior approval | 6m terrace/semi · 8m detached | Prior-approval notice + neighbour consultation | Neighbour objections on amenity |
| Full householder application | Beyond the above, or two-storey | Full planning permission | Daylight (45°/25°), bulk, garden retained |
| Conservation area | Case by case | Full planning permission | Character, roof form, boundary treatment |
The larger-home route is switched off on designated land — conservation areas such as Ashen and Belchamp Otten and Article 4 streets need a full application.
A fixed process built around how Braintree District Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Stour Valley North postcode and house type. We confirm your conservation and Article 4 status, how much rear-extension depth you have under permitted development, and score your odds against live Braintree District Council decisions.
We measure the original rear wall, floor and eaves levels, side and rear boundary distances and the neighbours' window positions — the numbers the depth limit and daylight splays depend on.
Chartered designers develop the single or two-storey rear extension to your brief, drawn inside the permitted-development limits or to Braintree District Council's extension design guidance, with the daylight angles shown.
We submit the certificate, prior-approval notice or application, handle validation and case-officer queries, and revise the drawings free until Braintree District Council issues its decision.
Often not. A single-storey rear extension up to 3 metres deep on a terrace or semi, or 4 metres on a detached house, and no higher than 4 metres, is usually permitted development in Stour Valley North. You will need to involve Braintree District Council for anything deeper via the larger-home route, for two-storey rear extensions, and for any rear extension in a conservation area such as Ashen and Belchamp Otten, where those permitted-development rights fall away.
The larger-home extension scheme lets a single-storey rear extension reach 6 metres on a terrace or semi, or 8 metres on a detached house — double the standard allowance. It is not automatic: you submit a prior-approval notification to Braintree District Council, neighbours are consulted, and if one objects on amenity grounds the council rules on it. It also does not apply on designated land such as Stour Valley North's conservation areas.
It is the daylight test Braintree District Council applies to protect neighbours. Drawn on plan, a line at 45 degrees from the midpoint of the neighbour's nearest ground-floor window should not be crossed by your extension; a companion 25-degree line is checked in section. If the projection breaches it, the extension is likely to be shortened or refused, so we test and prove it on the drawings before submission. This applies to your Stour Valley North address specifically.
A two-storey rear extension almost always needs a full householder application to Braintree District Council, as it sits outside permitted development on most homes. The council checks that it stays at least 7 metres from the rear boundary, does not overbear the neighbours and avoids new overlooking. We resolve the boundary gap, privacy and daylight on the plans so the application is decided on its merits. This applies to your Stour Valley North address specifically.
Frequently, yes. If the rear extension involves work to a shared wall, building up to the boundary, or excavating foundations near a neighbour's structure, the Party Wall etc. Act applies and you must serve notice — this is separate from Braintree District Council's planning decision. We flag it early and can prepare the drawings a party-wall surveyor needs alongside the planning set. This applies to your Stour Valley North address specifically.
