Dormer, hip-to-gable and mansard loft conversion drawings for Southwick and Wickham homes — prepared to Winchester City Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score 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. Southwick and Wickham contains Southwick, Wickham conservation areas (Southwick designated 1970), 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.
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 Southwick and Wickham those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Southwick and Wickham is determined against an 8-week statutory target.
Southwick (conservation area designated in 1970), Wickham (conservation area designated in 1969), Wickham and Knowle (civil parish within Southwick and Wickham), Boarhunt (civil parish within Southwick and Wickham), Newlands (civil parish within Southwick and Wickham) and Southwick and Widley (civil parish within Southwick and Wickham) — these are the Southwick and Wickham pockets our drawings cover most. Heritage designations here include Southwick and Wickham. Winchester City Council weighs each proposal against Winchester City Council's adopted local plan and its householder design guidance, where the 4,060 homes here are 15% 2000-2008, 14% pre-1900, 7% 1945-1954, which is what sets the realistic roof and rear-projection options. On roofs the borough is trussed-rafter roofs typical of 2000s building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, over 2000s houses and apartments (15% of 4,060 homes), Victorian and earlier houses (14%) and early postwar houses (7%).
Heritage designation is the single biggest variable in Southwick and Wickham, and it is address-specific: Southwick (conservation area designated in 1970) and Wickham (conservation area designated in 1969). 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, Southwick and Wickham takes in Wickham and Knowle, Boarhunt, Newlands and Southwick and Widley. No Article 4 direction is recorded for Winchester City Council, but Southwick and Wickham's 2 conservation areas still limit permitted development on those streets.
On stock, Southwick and Wickham is 2000s houses and apartments (15% of 4,060 homes), Victorian and earlier houses (14%) and early postwar houses (7%) — which is why trussed-rafter roofs typical of 2000s building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 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 Southwick and Wickham runs pre-1900 14% (550 homes), 1900-1918 1% (30 homes), 1919-1929 3% (120 homes), 1930-1939 2% (80 homes), 1945-1954 7% (300 homes), 1955-1964 2% (70 homes), 1965-1972 5% (220 homes), 1973-1982 4% (180 homes), 1983-1992 3% (140 homes), 1993-1999 2% (100 homes) and 2000-2008 15% (590 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, The Worthys and Whiteley and Shedfield, so a decision in Southwick and Wickham 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.

Southwick and Wickham's roofs set the brief. The borough is built largely from 2000s houses and apartments (15% of 4,060 homes), Victorian and earlier houses (14%) and early postwar houses (7%), and its lofts sit under trussed-rafter roofs typical of 2000s building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Winchester City Council assesses loft proposals against Winchester City Council's adopted local plan and its householder design guidance, and its case officers read each roof against the pair next door and the wider street before they read the plans.
That makes drawing quality decisive. We measure ridge and eaves heights, roof pitch and the existing stair, calculate the added volume against the permitted-development limits exactly, and show the workings on the drawings so Winchester City Council can verify them. Southwick and Wickham contains Southwick, Wickham conservation areas (Southwick designated 1970), so materials, fenestration and roof form are assessed against the appraisal, so we resolve it on the page rather than leave it for the case officer to raise.
Southwick and Wickham also carries protected streets — Southwick and Wickham among them. No Article 4 direction is recorded for Winchester City Council, but Southwick and Wickham's 2 conservation areas still limit permitted development on those streets. We check your address against those designations before a line is drawn.
Many Southwick and Wickham loft conversions proceed without planning permission — a rear dormer within the permitted-development volume limits (40 cubic metres on a terrace, 50 on a semi or detached house) is usually lawful. You will normally need a full application to Winchester City Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Winchester City Council's officers check first — and submit a validation-complete pack, whether that is a lawful development certificate or a full householder application.
Below is Winchester City Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Winchester City Council granted 97% of its householder applications in the year to 31 March 2026, and Southwick shapes what is approved here. Professionally prepared loft drawings anticipate those pressure points before submission, which is why complete, policy-literate packs are decided faster and refused less often than DIY applications.

Across Southwick, Wickham and Wickham and Knowle, the recurring loft is the rear dormer — a box across the back roof slope that turns a cramped attic into a full-height double bedroom and en-suite. On trussed-rafter roofs typical of 2000s building, that is usually the most efficient use of the roof; where the stock is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 4,060 homes here are 15% 2000-2008, 14% pre-1900, 7% 1945-1954, which is what sets the realistic roof and rear-projection options. We draw the dormer inside the volume allowance, keep the flat-roof build-up below the ridge, and set the face back from the eaves as the rules require — so the pack answers Winchester City Council's questions before they are asked. Where permitted-development rights are exhausted or removed, we prepare a householder application composed to the borough's roof-alteration guidance instead.

The right loft in Southwick and Wickham depends on your roof. This is how the main types compare on planning route and the space they add.
| Loft type | Permitted development? | Space & headroom | What Winchester City Council checks |
|---|---|---|---|
| Rear dormer | Usually yes, within volume limits | Full-height double room at the back | Volume, set-back from eaves, ridge height |
| Hip-to-gable | No — full application | Extends the whole side of the roof | Roof bulk and the symmetry of the pair |
| Mansard | No — full application | Maximum floor area across the roof | Street character, especially in conservation areas |
| Rooflights only | Usually yes (Class C) | Light and headroom, no extra footprint | Whether rooflights sit within the existing slope |
Route depends on your street — conservation areas such as Southwick and Wickham and Article 4 directions can remove permitted-development rights.
A fixed process built around how Winchester City Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Southwick and Wickham postcode and roof type. We confirm your conservation and Article 4 status, how much permitted-development volume you have left, and score your odds against live Winchester City Council decisions.
We measure ridge and eaves heights, roof pitch, joist levels and the existing stair — the numbers the volume calculation and head heights depend on.
Chartered designers develop the dormer, hip-to-gable or mansard to your brief, drawn inside the Class B limits or to Winchester City Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Winchester City Council issues its decision.
Often not. A rear dormer within 40 cubic metres on a terrace, or 50 on a semi-detached or detached house, set back from the eaves and no higher than the ridge, is usually permitted development. In Southwick and Wickham the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Southwick and Wickham or on streets with an Article 4 direction. Winchester City Council is the decision-maker.
Generally no. In conservation areas including Southwick and Wickham, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Winchester City Council. No Article 4 direction is recorded for Winchester City Council, but Southwick and Wickham's 2 conservation areas still limit permitted development on those streets. We check your exact address before drawing.
On trussed-rafter roofs typical of 2000s building, common across Southwick and Wickham, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, a hip-to-gable followed by a rear dormer gains far more usable space but needs planning permission. Our survey confirms which your roof supports before we draw. Winchester City Council is the decision-maker.
A householder planning application in Southwick and Wickham runs to a statutory eight-week target, and a lawful development certificate to eight weeks as well, though validation can add time if the pack is incomplete. We submit validation-complete drawings and manage case-officer queries to keep the decision on track. Winchester City Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Winchester City Council is council-stamped proof of that — worth having, because every buyer's solicitor will ask for it when you sell. We prepare and submit the certificate application with the same drawing pack. This applies to your Southwick and Wickham address specifically.
Every roof is different, so we quote each Southwick and Wickham project individually — a fixed, no-obligation price back within one working day.
