Back-of-house extension drawings for Bacton homes — the glazed kitchen-diner across the rear, drawn to Mid Suffolk District Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Mid Suffolk 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. Bacton contains the Finningham conservation area (Finningham designated 1973), 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 Finningham those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Bacton is determined against an 8-week statutory target.
Finningham (conservation area designated in 1973), Wyverstone (civil parish within Bacton), Cotton (civil parish within Bacton), Finningham (civil parish within Bacton) and Westhorpe (civil parish within Bacton) — these are the Bacton pockets our drawings cover most. Heritage designations here include Finningham. Mid Suffolk District Council weighs each proposal against Mid Suffolk District Council's development plan and the design policies it applies to householder applications, where the 1,330 homes here are 21% pre-1900, 12% 1973-1982, 11% 1965-1972, 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 trussed roofs typical of 1970s building, over Victorian and earlier houses (21% of 1,330 homes), 1970s and early-1980s houses (12%) and late-1960s and early-1970s houses (11%).
Before anything is drawn we check your address against the designations that apply in Bacton: Finningham (conservation area designated in 1973). Inside those boundaries permitted development is curtailed and Mid Suffolk 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, Bacton takes in Wyverstone, Cotton, Finningham and Westhorpe. No Article 4 direction is recorded for Mid Suffolk District Council, but Bacton's 1 conservation area still limit permitted development on those streets.
On stock, Bacton is Victorian and earlier houses (21% of 1,330 homes), 1970s and early-1980s houses (12%) and late-1960s and early-1970s houses (11%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow trussed roofs typical of 1970s building govern what a loft or rear projection can realistically be. Mid Suffolk District Council decided 371 householder applications in the latest published year and granted 95%, with 77% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Bacton runs pre-1900 21% (280 homes), 1900-1918 1% (10 homes), 1919-1929 2% (20 homes), 1930-1939 5% (70 homes), 1945-1954 5% (70 homes), 1955-1964 3% (40 homes), 1965-1972 11% (140 homes), 1973-1982 12% (160 homes), 1983-1992 9% (120 homes), 1993-1999 5% (70 homes) and 2000-2008 5% (60 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.
Mid Suffolk District Council also decides for Claydon & Barham, Debenham, Elmswell & Woolpit, Eye, Fressingfield, Gislingham, Hoxne & Worlingworth and Mendlesham, so a decision in Bacton 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 Bacton 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 (21% of 1,330 homes), 1970s and early-1980s houses (12%) and late-1960s and early-1970s houses (11%), most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Mid Suffolk District Council scrutinises. The council reads the proposal against Mid Suffolk District Council's development plan and the design policies it applies to householder applications, 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. Bacton contains the Finningham conservation area (Finningham designated 1973), 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 — Finningham among Bacton's — the larger-home extension route is switched off and even a modest rear addition needs consent. No Article 4 direction is recorded for Mid Suffolk District Council, but Bacton's 1 conservation area still limit permitted development on those streets. We confirm the designation before the survey.
Many single-storey rear extensions in Bacton are permitted development and need no application. You will normally need to apply to Mid Suffolk 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 Mid Suffolk 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 Mid Suffolk District Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Mid Suffolk District Council granted 95% of its householder applications in the year to 31 March 2026, and Finningham 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 Finningham, Wyverstone and Cotton, 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 (21% of 1,330 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 1,330 homes here are 21% pre-1900, 12% 1973-1982, 11% 1965-1972, 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 Mid Suffolk 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 Bacton back-of-house projects come up most often:

How far you can extend at the back in Bacton depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Mid Suffolk 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 Finningham and Article 4 streets need a full application.
A fixed process built around how Mid Suffolk District Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Bacton 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 Mid Suffolk 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 Mid Suffolk 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 Mid Suffolk 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 Bacton. You will need to involve Mid Suffolk 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 Finningham, 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 Mid Suffolk 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 Bacton's conservation areas.
It is the daylight test Mid Suffolk 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 Bacton address specifically.
A two-storey rear extension almost always needs a full householder application to Mid Suffolk 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 Bacton 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 Mid Suffolk 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 Bacton address specifically.
We price each Bacton rear extension on its own footprint and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Mid Suffolk District Council approves, and we confirm at the outset whether your extension is permitted development, needs prior approval, or a full application.
