Single-storey, double-storey, rear and side extension drawings for Bardwell homes — measured to West Suffolk Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
West Suffolk Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. Bardwell contains Bardwell, Barnham, Euston conservation areas (Bardwell designated 2000), 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.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. In conservation areas such as Bardwell, Barnham and Euston those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Bardwell is determined against an 8-week statutory target.
Bardwell (conservation area designated in 2000), Barnham (conservation area designated in 1973), Euston (conservation area designated in 1973), Fakenham Magna (conservation area designated in 1973), Honington (conservation area designated in 2004), Barnham (civil parish within Bardwell), Coney Weston (civil parish within Bardwell), Euston (civil parish within Bardwell), Fakenham Magna (civil parish within Bardwell), Honington (civil parish within Bardwell) and Sapiston (civil parish within Bardwell) — these are the Bardwell pockets our drawings cover most. Heritage designations here include Bardwell, Barnham, Euston, Fakenham Magna and Honington. West Suffolk Council weighs each proposal against West Suffolk Council's development plan and the design policies it applies to householder applications, where the 1,160 homes here are 31% pre-1900, 12% 1955-1964, 12% 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 gabled roofs typical of that period's building, over Victorian and earlier houses (31% of 1,160 homes), late-1950s and early-1960s houses (12%) and late-1960s and early-1970s houses (12%).
What is permitted in Bardwell turns on designation first, so that is where we start: Bardwell (conservation area designated in 2000), Barnham (conservation area designated in 1973), Euston (conservation area designated in 1973), Fakenham Magna (conservation area designated in 1973) and Honington (conservation area designated in 2004). Inside those boundaries permitted development is curtailed and West Suffolk 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, Bardwell takes in Barnham, Coney Weston, Euston, Fakenham Magna, Honington and Sapiston. No Article 4 direction is recorded for West Suffolk Council, but Bardwell's 5 conservation areas still limit permitted development on those streets.
On stock, Bardwell is Victorian and earlier houses (31% of 1,160 homes), late-1950s and early-1960s houses (12%) and late-1960s and early-1970s houses (12%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. West Suffolk Council decided 489 householder applications in the latest published year and granted 95%, with 56% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Bardwell runs pre-1900 31% (360 homes), 1900-1918 1% (10 homes), 1919-1929 2% (20 homes), 1930-1939 4% (50 homes), 1945-1954 7% (80 homes), 1955-1964 12% (140 homes), 1965-1972 12% (140 homes), 1973-1982 10% (120 homes), 1983-1992 5% (60 homes), 1993-1999 3% (40 homes) and 2000-2008 4% (50 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.
West Suffolk Council also decides for Abbeygate, Barningham, Brandon East, Chedburgh & Chevington, Haverhill Central, Horringer, Ixworth and Kentford & Moulton, so a decision in Bardwell 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.

Bardwell homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from Victorian and earlier houses (31% of 1,160 homes), late-1950s and early-1960s houses (12%) and late-1960s and early-1970s houses (12%), so a Victorian terrace usually wants a rear or side-return infill, while an interwar semi has room for a wider single-storey wrap or a two-storey side addition. West Suffolk Council judges every one of them against West Suffolk Council's development plan and the design policies it applies to householder applications, weighing footprint, height and the impact on the house next door before it looks at the elevations.
That is why the drawings decide the outcome. We set the extension depth against the permitted-development limits precisely, keep the eaves and ridge within the allowances, and plot the 45-degree daylight lines to the neighbours' windows so the case officer can see the amenity test is passed. Bardwell contains Bardwell, Barnham, Euston conservation areas (Bardwell designated 2000), so materials, fenestration and roof form are assessed against the appraisal, so we design around it from the first sketch rather than discover it at validation.
Bardwell also protects whole streets — Bardwell, Barnham, Euston, Fakenham Magna and Honington among them. No Article 4 direction is recorded for West Suffolk Council, but Bardwell's 5 conservation areas still limit permitted development on those streets. On designated land the larger-home extension route and most side extensions stop being permitted development, so we confirm your address against those layers before drawing a line.
Plenty of Bardwell extensions are permitted development and need no planning application — a single-storey rear extension within the depth and height limits is the common case. You will normally need to apply to West Suffolk Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships West Suffolk Council's officers weigh first — and submit a validation-complete pack, whether that is a lawful development certificate, a prior-approval notification or a full householder application.
Below is West Suffolk Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. West Suffolk Council granted 95% of its householder applications in the year to 31 March 2026, and Bardwell shapes what is approved here. A complete, policy-literate extension pack anticipates those pressure points before submission, which is why professionally drawn applications are decided faster and refused less often than DIY ones.

Across Bardwell, Barnham and Euston, the extension that lands most often is the single-storey rear addition — a glazed kitchen-diner across the back of the house, kept within the permitted-development depth or taken to a full application where the ground floor wants more. On the borough's victorian and earlier houses (31% of 1,160 homes), a side-return infill frequently pairs with it to square off the plan; on wider late-1960s and early-1970s houses (12%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 1,160 homes here are 31% pre-1900, 12% 1955-1964, 12% 1965-1972, which is what sets the realistic roof and rear-projection options. We size the extension to the amenity and daylight tests, match the roof and materials to the host house, and keep enough garden to satisfy West Suffolk Council's space standards — so the scheme answers the borough's questions before an objection can raise them. Where permitted-development rights are used up or removed, we prepare the householder application to the council's extension design guidance instead.
We draw extensions on every street in the borough. A few of the neighbourhoods where Bardwell projects come up most often:

The right extension in Bardwell depends on your house type and how much garden you can give up. This is how the main options compare on planning route and what they add.
| Extension type | Permitted development? | What it adds | What West Suffolk Council checks |
|---|---|---|---|
| Single-storey rear | Often, within 3m/4m depth (6m/8m via prior approval) | Bigger kitchen-diner across the back | Depth, height, neighbour daylight (45°) |
| Side-return infill | Sometimes, if within width and height limits | Squares off an L-shaped ground floor | Width vs the original house, glazing to boundary |
| Two-storey rear/side | No — full application | Extra bedroom or bathroom above | Bulk, overlooking, 7m rear-boundary gap |
| Wraparound (rear + side) | No — full application | Whole-width open-plan ground floor | Combined footprint and garden retained |
Route depends on your street — conservation areas such as Bardwell and Barnham and Article 4 directions can remove permitted-development rights.
A fixed process built around how West Suffolk Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Bardwell postcode and house type. We confirm your conservation and Article 4 status, how much permitted-development depth you have left, and score your odds against live West Suffolk Council decisions.
We measure the existing footprint, floor and eaves levels, boundary distances and the neighbours' window positions — the numbers the depth limits and daylight tests depend on.
Chartered designers develop the single-storey, two-storey or side extension to your brief, drawn inside the permitted-development limits or to West Suffolk Council's extension design guidance.
We submit the certificate, prior-approval notice or application, manage validation and case-officer queries, and revise the drawings free until West Suffolk Council issues its decision.
Not always. 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 Bardwell you will need to apply to West Suffolk Council for two-storey extensions, side extensions wider than half the house, anything forward of the front wall, deeper rear extensions under the larger-home prior-approval route, and any extension in a conservation area such as Bardwell and Barnham.
Standard permitted development allows 3 metres on a terraced or semi-detached house and 4 metres on a detached one. The larger-home extension scheme can double that to 6 or 8 metres, but it needs a prior-approval notification to West Suffolk Council and a neighbour-consultation period, and it does not apply on designated land such as Bardwell's conservation areas. We confirm which route your property qualifies for before drawing.
Two-storey and double-storey extensions almost always need a full householder application to West Suffolk Council, because they fall outside permitted development on most homes. The council looks closely at bulk, overlooking of neighbours and the 7-metre gap a two-storey rear extension must keep from the rear boundary. We design to those tests and show the daylight and privacy angles on the drawings. This applies to your Bardwell address specifically.
A householder planning application in Bardwell runs to a statutory eight-week target, a larger-home prior-approval notification to around six weeks including the neighbour-consultation period, and a lawful development certificate to eight weeks. Incomplete submissions stall at validation, so we submit a complete pack and manage officer queries to keep the decision on schedule. West Suffolk Council is the decision-maker.
Yes — planning permission and building regulations are separate consents, and almost every extension needs both. Planning governs whether you can build it; building control governs how it is built, covering structure, insulation, drainage and fire safety. We prepare the building-regulations drawings alongside the planning set so West Suffolk Council's building control or an approved inspector can sign the work off. This applies to your Bardwell address specifically.
Every house and brief is different, so we price each Bardwell extension individually and send a fixed, no-obligation quote back within one working day.
