Back-of-house extension drawings for Whiteley and Shedfield homes — the glazed kitchen-diner across the rear, drawn to Winchester City Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Winchester City Council granted 97% of the householder planning decisions it made in its latest published year — 10 points above the 87% England-wide householder average. Whiteley and Shedfield contains Botley, Shedfield conservation areas (Botley designated 1975), 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) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Winchester City Council needs a full application. In conservation areas such as Botley and Shedfield those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Whiteley and Shedfield is determined against an 8-week statutory target.
Botley (conservation area designated in 1975), Shedfield (conservation area designated in 1990), Shedfield (civil parish within Whiteley and Shedfield), Curdridge (civil parish within Whiteley and Shedfield) and Whiteley (civil parish within Whiteley and Shedfield) — these are the Whiteley and Shedfield pockets our drawings cover most. Heritage designations here include Botley and Shedfield. Winchester City Council weighs each proposal against the adopted Winchester local plan and Winchester City Council's design guidance for householder work, where the 4,710 homes here are 17% 1993-1999, 15% 2000-2008, 8% pre-1900, which is what sets the realistic roof and rear-projection options. On roofs the borough is trussed-rafter roofs typical of 1990s building and trussed-rafter roofs typical of 2000s building, over 1990s estate houses (17% of 4,710 homes), 2000s houses and apartments (15%) and Victorian and earlier houses (8%).
Heritage designation is the single biggest variable in Whiteley and Shedfield, and it is address-specific: Botley (conservation area designated in 1975) and Shedfield (conservation area designated in 1990). Inside those boundaries permitted development is curtailed and Winchester City 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, Whiteley and Shedfield takes in Shedfield, Curdridge and Whiteley. No Article 4 direction is recorded for Winchester City Council, but Whiteley and Shedfield's 2 conservation areas still limit permitted development on those streets.
On stock, Whiteley and Shedfield is 1990s estate houses (17% of 4,710 homes), 2000s houses and apartments (15%) and Victorian and earlier houses (8%) — which is why trussed-rafter roofs typical of 1990s building and trussed-rafter roofs typical of 2000s building govern what a loft or rear projection can realistically be. Winchester City Council decided 540 householder applications in the latest published year and granted 97%, with 55% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Whiteley and Shedfield runs pre-1900 8% (370 homes), 1900-1918 3% (150 homes), 1919-1929 1% (50 homes), 1930-1939 1% (70 homes), 1945-1954 2% (90 homes), 1955-1964 4% (200 homes), 1965-1972 2% (80 homes), 1973-1982 3% (120 homes), 1983-1992 1% (70 homes), 1993-1999 17% (800 homes) and 2000-2008 15% (720 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.
Winchester City Council also decides for Bishop's Waltham, Southwick and Wickham and The Worthys, so a decision in Whiteley and Shedfield 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 Whiteley and Shedfield home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from 1990s estate houses (17% of 4,710 homes), 2000s houses and apartments (15%) and Victorian and earlier houses (8%), most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Winchester City Council scrutinises. The council reads the proposal against the adopted Winchester local plan and Winchester City 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. Whiteley and Shedfield contains Botley, Shedfield conservation areas (Botley designated 1975), 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 — Botley and Shedfield among Whiteley and Shedfield's — the larger-home extension route is switched off and even a modest rear addition needs consent. No Article 4 direction is recorded for Winchester City Council, but Whiteley and Shedfield's 2 conservation areas still limit permitted development on those streets. We confirm the designation before the survey.
Many single-storey rear extensions in Whiteley and Shedfield are permitted development and need no application. You will normally need to apply to Winchester City 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 Winchester City 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 Winchester City Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Winchester City Council granted 97% of its householder applications in the year to 31 March 2026, and Botley 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 Botley, Shedfield and Shedfield, 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 1990s estate houses (17% of 4,710 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 4,710 homes here are 17% 1993-1999, 15% 2000-2008, 8% pre-1900, 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 Winchester City 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.

How far you can extend at the back in Whiteley and Shedfield depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Winchester City 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 Botley and Shedfield and Article 4 streets need a full application.
A fixed process built around how Winchester City Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Whiteley and Shedfield 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 Winchester City 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 Winchester City 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 Winchester City 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 Whiteley and Shedfield. You will need to involve Winchester City 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 Botley and Shedfield, 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 Winchester City 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 Whiteley and Shedfield's conservation areas.
It is the daylight test Winchester City 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 Whiteley and Shedfield address specifically.
A two-storey rear extension almost always needs a full householder application to Winchester City 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 Whiteley and Shedfield 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 Winchester City 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 Whiteley and Shedfield address specifically.
