Single-storey, double-storey, rear and side extension drawings for Padstow homes — measured to Cornwall Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Cornwall Council granted 97% of the householder planning decisions it made in its latest published year — 10 points above the 87% England-wide householder average. Padstow contains LITTLE PETHERICK, PADSTOW conservation areas (LITTLE PETHERICK designated 1997), 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 interwar (1918–1939) 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. In conservation areas such as LITTLE PETHERICK and PADSTOW those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Padstow is determined against an 8-week statutory target.
LITTLE PETHERICK (conservation area designated in 1997), PADSTOW (conservation area designated in 1974), St. Merryn (civil parish within Padstow), St. Ervan (civil parish within Padstow), St. Eval (civil parish within Padstow) and St. Issey (civil parish within Padstow) — these are the Padstow pockets our drawings cover most. Heritage designations here include LITTLE PETHERICK and PADSTOW. Cornwall Council weighs each proposal against Cornwall Council's adopted local plan and its householder design guidance, where the 4,480 homes here are 17% pre-1900, 10% 1993-1999, 10% 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 trussed-rafter roofs typical of 1990s building, over Victorian and earlier houses (17% of 4,480 homes), 1990s estate houses (10%) and 1930s semi-detached and detached houses (10%).
Padstow's designated heritage is specific, and it is the first thing we check against your address: LITTLE PETHERICK (conservation area designated in 1997) and PADSTOW (conservation area designated in 1974). Inside those boundaries permitted development is curtailed and Cornwall 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, Padstow takes in St. Merryn, St. Ervan, St. Eval and St. Issey. No Article 4 direction is recorded for Cornwall Council, but Padstow's 2 conservation areas still limit permitted development on those streets.
On stock, Padstow is Victorian and earlier houses (17% of 4,480 homes), 1990s estate houses (10%) and 1930s semi-detached and detached houses (10%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 1990s building govern what a loft or rear projection can realistically be. Cornwall Council decided 1,863 householder applications in the latest published year and granted 97%, with 76% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Padstow runs pre-1900 17% (780 homes), 1900-1918 2% (100 homes), 1919-1929 3% (120 homes), 1930-1939 10% (440 homes), 1945-1954 9% (390 homes), 1955-1964 5% (230 homes), 1965-1972 5% (240 homes), 1973-1982 5% (240 homes), 1983-1992 8% (370 homes), 1993-1999 10% (450 homes) and 2000-2008 6% (290 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.
Cornwall Council also decides for Bodmin St Petroc's, Bude, Camborne Trelowarren, Camelford & Boscastle, Falmouth Arwenack, Feock & Kea, Hayle West and Land's End, so a decision in Padstow 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.

Padstow 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 (17% of 4,480 homes), 1990s estate houses (10%) and 1930s semi-detached and detached houses (10%), 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. Cornwall Council judges every one of them against Cornwall Council's adopted local plan and its householder design guidance, 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. Padstow contains LITTLE PETHERICK, PADSTOW conservation areas (LITTLE PETHERICK designated 1997), 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.
Padstow also protects whole streets — LITTLE PETHERICK and PADSTOW among them. No Article 4 direction is recorded for Cornwall Council, but Padstow's 2 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 Padstow 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 Cornwall Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Cornwall 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 Cornwall Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Cornwall Council granted 97% of its householder applications in the year to 31 March 2026, and LITTLE PETHERICK 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 LITTLE PETHERICK, PADSTOW and St. Merryn, 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 (17% of 4,480 homes), a side-return infill frequently pairs with it to square off the plan; on wider 1930s semi-detached and detached houses (10%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 4,480 homes here are 17% pre-1900, 10% 1993-1999, 10% 1930-1939, 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 Cornwall 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 Padstow projects come up most often:

The right extension in Padstow 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 Cornwall 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 LITTLE PETHERICK and PADSTOW and Article 4 directions can remove permitted-development rights.
A fixed process built around how Cornwall Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Padstow 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 Cornwall 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 Cornwall 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 Cornwall 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 Padstow you will need to apply to Cornwall 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 LITTLE PETHERICK and PADSTOW.
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 Cornwall Council and a neighbour-consultation period, and it does not apply on designated land such as Padstow'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 Cornwall 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 Padstow address specifically.
A householder planning application in Padstow 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. Cornwall 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 Cornwall Council's building control or an approved inspector can sign the work off. This applies to your Padstow address specifically.
Every house and brief is different, so we price each Padstow extension individually and send a fixed, no-obligation quote back within one working day.
