Dormer, hip-to-gable and mansard loft conversion drawings for St Radigunds homes — prepared to Dover District Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Dover District Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. St Radigunds contains Dour Street - Extension, Dover - Charlton Green, Dover - Dour Street conservation areas (Dover - Charlton Green designated 1987), 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.
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. St Radigunds carries at least one Article 4 direction, and conservation areas including Dour Street - Extension, Dover - Charlton Green and Dover - Dour Street remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in St Radigunds is determined against an 8-week statutory target.
Dour Street - Extension (designated conservation area), Dover - Charlton Green (conservation area designated in 1987), Dover - Dour Street (conservation area designated in 1987), Dover - London Road (conservation area designated in 1987) and Dover (civil parish within St Radigunds) — these are the St Radigunds pockets our drawings cover most. Heritage designations here include Dour Street - Extension, Dover - Charlton Green, Dover - Dour Street and Dover - London Road. Dover District Council weighs each proposal against the adopted Dover local plan and Dover District Council's design guidance for householder work, where the 3,740 homes here are 47% pre-1900, 11% 1930-1939, 9% 1993-1999, 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 hipped roofs with shallow pitches typical of 1930s building, over Victorian and earlier houses (47% of 3,740 homes), 1930s semi-detached and detached houses (11%) and 1990s estate houses (9%).
What is permitted in St Radigunds turns on designation first, so that is where we start: Dour Street - Extension (designated conservation area), Dover - Charlton Green (conservation area designated in 1987), Dover - Dour Street (conservation area designated in 1987) and Dover - London Road (conservation area designated in 1987). Inside those boundaries permitted development is curtailed and Dover District 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, St Radigunds takes in Dover. Dover District Council has 55 recorded Article 4 directions — check the address before assuming PD applies in St Radigunds.
On stock, St Radigunds is Victorian and earlier houses (47% of 3,740 homes), 1930s semi-detached and detached houses (11%) and 1990s estate houses (9%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and hipped roofs with shallow pitches typical of 1930s building govern what a loft or rear projection can realistically be. Dover District Council decided 379 householder applications in the latest published year and granted 92%, with 83% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for St Radigunds runs pre-1900 47% (1,760 homes), 1900-1918 4% (160 homes), 1919-1929 1% (40 homes), 1930-1939 11% (400 homes), 1945-1954 2% (70 homes), 1955-1964 1% (30 homes), 1965-1972 3% (100 homes), 1973-1982 7% (250 homes), 1983-1992 3% (100 homes), 1993-1999 9% (320 homes) and 2000-2008 3% (110 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.
Dover District Council also decides for Dover Downs & River, Eastry Rural, Middle Deal, North Deal, Sandwich, Tower Hamlets, Town & Castle and Walmer, so a decision in St Radigunds 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 Article 4 Direction 3, 1990, Town and Country Planning General Development Order 1988 (as Amended), Article 4 Direction No. 1, 1992, Town and Country Planning General Development Order 1988 (as Amended), Article 4 Direction No. 4 1990, Town and Country Planning General Development Order 1988 (as amended) and Article 4 Direction No. 5 1990, Town and Country Planning General Development Order 1988 (as amended). 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.

St Radigunds's roofs set the brief. The borough is built largely from Victorian and earlier houses (47% of 3,740 homes), 1930s semi-detached and detached houses (11%) and 1990s estate houses (9%), and its lofts sit under steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and hipped roofs with shallow pitches typical of 1930s building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Dover District Council assesses loft proposals against the adopted Dover local plan and Dover District Council's design guidance for householder work, 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 Dover District Council can verify them. St Radigunds contains Dour Street - Extension, Dover - Charlton Green, Dover - Dour Street conservation areas (Dover - Charlton Green designated 1987), 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.
St Radigunds also carries protected streets — Dour Street - Extension, Dover - Charlton Green, Dover - Dour Street and Dover - London Road among them. Dover District Council has 55 recorded Article 4 directions — check the address before assuming PD applies in St Radigunds. We check your address against those designations before a line is drawn.
Many St Radigunds 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 Dover District Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Dover District 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 Dover District Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Dover District Council granted 92% of its householder applications in the year to 31 March 2026, and Dour Street - Extension 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 Dour Street - Extension, Dover - Charlton Green and Dover - Dour Street, 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 steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, that is usually the most efficient use of the roof; where the stock is hipped roofs with shallow pitches typical of 1930s building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 3,740 homes here are 47% pre-1900, 11% 1930-1939, 9% 1993-1999, 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 Dover District 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.
We draw loft conversions on every street in the borough. A few of the neighbourhoods where St Radigunds roofs come up most often:

The right loft in St Radigunds 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 Dover District 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 Dour Street - Extension and Dover - Charlton Green and Article 4 directions can remove permitted-development rights.
A fixed process built around how Dover District Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your St Radigunds 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 Dover District 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 Dover District Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Dover District 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 St Radigunds the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Dour Street - Extension and Dover - Charlton Green or on streets with an Article 4 direction. Dover District Council is the decision-maker.
Generally no. In conservation areas including Dour Street - Extension and Dover - Charlton Green, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Dover District Council. Dover District Council has 55 recorded Article 4 directions — check the address before assuming PD applies in St Radigunds. We check your exact address before drawing.
On steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, common across St Radigunds, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is hipped roofs with shallow pitches typical of 1930s 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. Dover District Council is the decision-maker.
A householder planning application in St Radigunds 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. Dover District Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Dover District 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 St Radigunds address specifically.
Every roof is different, so we quote each St Radigunds project individually — a fixed, no-obligation price back within one working day. The quote covers the full drawing pack with free revisions until Dover District Council approves, and we tell you upfront whether your loft qualifies as permitted development.
