Single-storey, double-storey, rear and side extension drawings for South West Holderness homes — measured to East Riding of Yorkshire Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
East Riding of Yorkshire Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. South West Holderness contains Hedon, Hedon Haven, Paull conservation areas (Hedon designated 1968), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its mixed housing stock sets the design brief street by street.
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. South West Holderness carries at least one Article 4 direction, and conservation areas including Hedon, Hedon Haven and Paull remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in South West Holderness is determined against an 8-week statutory target.
Hedon (conservation area designated in 1968), Hedon Haven (conservation area designated in 1992), Paull (conservation area designated in 1991), Preston (conservation area designated in 1991), Hedon (civil parish within South West Holderness), Paull (civil parish within South West Holderness), Preston (civil parish within South West Holderness) and Thorngumbald (civil parish within South West Holderness) — these are the South West Holderness pockets our drawings cover most. Heritage designations here include Hedon, Hedon Haven, Paull and Preston. East Riding of Yorkshire Council weighs each proposal against East Riding of Yorkshire Council's adopted local plan and its householder design guidance, where the 6,710 homes here are 20% 1973-1982, 14% 1983-1992, 12% 2000-2008, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow trussed roofs typical of 1970s building and trussed-rafter roofs typical of 1980s building, over 1970s and early-1980s houses (20% of 6,710 homes), 1980s estate houses (14%) and 2000s houses and apartments (12%).
Before anything is drawn we check your address against the designations that apply in South West Holderness: Hedon (conservation area designated in 1968), Hedon Haven (conservation area designated in 1992), Paull (conservation area designated in 1991) and Preston (conservation area designated in 1991). Inside those boundaries permitted development is curtailed and East Riding of Yorkshire 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, South West Holderness takes in Hedon, Paull, Preston and Thorngumbald. East Riding of Yorkshire Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in South West Holderness.
On stock, South West Holderness is 1970s and early-1980s houses (20% of 6,710 homes), 1980s estate houses (14%) and 2000s houses and apartments (12%) — which is why shallow trussed roofs typical of 1970s building and trussed-rafter roofs typical of 1980s building govern what a loft or rear projection can realistically be. East Riding of Yorkshire Council decided 830 householder applications in the latest published year and granted 92%, with 95% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for South West Holderness runs pre-1900 8% (510 homes), 1900-1918 2% (120 homes), 1919-1929 2% (110 homes), 1930-1939 6% (390 homes), 1945-1954 4% (290 homes), 1955-1964 11% (710 homes), 1965-1972 10% (670 homes), 1973-1982 20% (1,310 homes), 1983-1992 14% (920 homes), 1993-1999 9% (610 homes) and 2000-2008 12% (810 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.
East Riding of Yorkshire Council also decides for Beverley Rural, Bridlington North, Bridlington South, Dale, Driffield and Rural, East Wolds and Coastal, Goole South and Hessle, so a decision in South West Holderness 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 Article 4 directions recorded for this council include Alpine Villa (Beck Cottage), Atwick, Atwick Hall, Atwick, Clifton House, Atwick and Green View, Atwick. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

South West Holderness homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from 1970s and early-1980s houses (20% of 6,710 homes), 1980s estate houses (14%) and 2000s houses and apartments (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. East Riding of Yorkshire Council judges every one of them against East Riding of Yorkshire 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. South West Holderness contains Hedon, Hedon Haven, Paull conservation areas (Hedon designated 1968), 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.
South West Holderness also protects whole streets — Hedon, Hedon Haven, Paull and Preston among them. East Riding of Yorkshire Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in South West Holderness. 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 South West Holderness 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 East Riding of Yorkshire Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships East Riding of Yorkshire 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 East Riding of Yorkshire Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. East Riding of Yorkshire Council granted 92% of its householder applications in the year to 31 March 2026, and Hedon 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 Hedon, Hedon Haven and Paull, 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 1970s and early-1980s houses (20% of 6,710 homes), a side-return infill frequently pairs with it to square off the plan; on wider 2000s houses and apartments (12%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 6,710 homes here are 20% 1973-1982, 14% 1983-1992, 12% 2000-2008, 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 East Riding of Yorkshire 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 South West Holderness projects come up most often:

The right extension in South West Holderness 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 East Riding of Yorkshire 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 Hedon and Hedon Haven and Article 4 directions can remove permitted-development rights.
A fixed process built around how East Riding of Yorkshire Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your South West Holderness 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 East Riding of Yorkshire 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 East Riding of Yorkshire 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 East Riding of Yorkshire 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 South West Holderness you will need to apply to East Riding of Yorkshire 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 Hedon and Hedon Haven.
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 East Riding of Yorkshire Council and a neighbour-consultation period, and it does not apply on designated land such as South West Holderness'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 East Riding of Yorkshire 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 South West Holderness address specifically.
A householder planning application in South West Holderness 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. East Riding of Yorkshire 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 East Riding of Yorkshire Council's building control or an approved inspector can sign the work off. This applies to your South West Holderness address specifically.
