Hip-to-gable drawings for Swale semis and end-terraces — building the sloping hipped end up into a flat gable wall to unlock the full width of the roof, drawn to Swale Borough Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Swale Borough Council granted 94% of the householder planning decisions it made in its latest published year — 7 points above the 87% England-wide householder average. Swale contains Badlesmere, Bexon, Borden - Chestnut Street conservation areas (Badlesmere designated 1982), 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 Swale Borough Council needs a full application. Swale carries at least one Article 4 direction, and conservation areas including Badlesmere, Bexon and Borden - Chestnut Street remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Swale is determined against an 8-week statutory target.
Badlesmere (conservation area designated in 1982), Bexon (conservation area designated in 2026), Borden - Chestnut Street (conservation area designated in 1976), Borden - Harmans Corner (conservation area designated in 1971), Borden - Hearts Delight (conservation area designated in 1999), Borden - The Street (conservation area designated in 1971), Boughton - Boughton Church (conservation area designated in 1976), Boughton - Boughton Street (conservation area designated in 1970), Abbey (ward of Swale), Borden and Grove Park (ward of Swale), Boughton and Courtenay (ward of Swale), East Downs (ward of Swale), Sheerness (ward of Swale), Teynham and Lynsted (ward of Swale), Watling (ward of Swale) and West Downs (ward of Swale) — these are the Swale pockets our drawings cover most. Heritage designations here include Badlesmere, Bexon, Borden - Chestnut Street, Borden - Harmans Corner, Borden - Hearts Delight, Borden - The Street, Boughton - Boughton Church and Boughton - Boughton Street. Swale Borough Council weighs each proposal against Swale Borough Council's adopted local plan and its householder design guidance, where the 22,440 homes here are 31% pre-1900, 7% 1955-1964, 5% 1965-1972, 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 shallow gabled roofs typical of that period's building, over Victorian and earlier houses (31% of 22,440 homes), late-1950s and early-1960s houses (7%) and late-1960s and early-1970s houses (5%).
Heritage designation is the single biggest variable in Swale, and it is address-specific: Badlesmere (conservation area designated in 1982), Bexon (conservation area designated in 2026), Borden - Chestnut Street (conservation area designated in 1976), Borden - Harmans Corner (conservation area designated in 1971), Borden - Hearts Delight (conservation area designated in 1999), Borden - The Street (conservation area designated in 1971), Boughton - Boughton Church (conservation area designated in 1976) and Boughton - Boughton Street (conservation area designated in 1970). Inside those boundaries permitted development is curtailed and Swale Borough 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, Swale takes in Abbey, Borden and Grove Park, Boughton and Courtenay, East Downs, Sheerness, Teynham and Lynsted, Watling and West Downs. Swale Borough Council has 22 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in the district.
On stock, Swale is Victorian and earlier houses (31% of 22,440 homes), late-1950s and early-1960s houses (7%) and late-1960s and early-1970s houses (5%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. Swale Borough Council decided 329 householder applications in the latest published year and granted 94%, with 37% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Swale runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 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.
Swale Borough Council also decides for Abbey, Borden and Grove Park, Boughton and Courtenay, East Downs, Sheerness, Teynham and Lynsted, Watling and West Downs, so a decision in Swale 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 1 and 2 Flint Cottages, 20 East Street, 43-47, 49-51, 54, 56, 57, 59-72 Marine Parade and 49, 88, 90, 104, 114-128(evens), 132-140(evens) The Street and 1 & 2 Chapel Cottages. 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.

The hip-to-gable is the semi's loft, and Swale has the stock that needs it — the borough runs to Victorian and earlier houses (31% of 22,440 homes), late-1950s and early-1960s houses (7%) and late-1960s and early-1970s houses (5%), and wherever the roof is hipped it wastes the triangle of space where the slope cuts in at the side. Build that hip up into a gable wall and the loft gains full-height room right across the width, usually with a rear dormer behind it. Swale Borough Council judges the scheme against Swale Borough Council's adopted local plan and its householder design guidance, and because the gable is a side elevation it is read against the neighbouring house first.
That neighbour relationship is the drawing's job. We build the gable to the original ridge line, match the brick or render and the verge detail to the host, and where the house is one of a mirrored pair we show the new gable against the neighbour's retained hip so the officer can weigh the balance. Swale contains Badlesmere, Bexon, Borden - Chestnut Street conservation areas (Badlesmere designated 1982), so materials, fenestration and roof form are assessed against the appraisal, and on a paired roof that is precisely the test a hip-to-gable has to pass.
Where Swale's streets are designated — Badlesmere, Bexon, Borden - Chestnut Street, Borden - Harmans Corner, Borden - Hearts Delight, Borden - The Street, Boughton - Boughton Church and Boughton - Boughton Street among them — a hip-to-gable is scrutinised hard, because losing a hip changes the roofscape the area is protected for. Swale Borough Council has 22 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in the district. We check the designation before the gable is drawn.
A hip-to-gable in Swale is not permitted development — extending the roof up and out over the hip takes it past what Class B allows — so it needs a full application to Swale Borough Council. These are the points the council weighs:
We draw the new gable to the existing ridge, the verge and materials matched to the host, and the balance with the neighbour's retained hip — the side-elevation relationships Swale Borough Council's officers check first — and submit a validation-complete householder application, usually with the rear dormer on the same drawings.
Below is Swale Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Swale Borough Council granted 94% of 329 householder decisions in the year to 31 March 2026, 37% of them inside eight weeks. A hip-to-gable turns on side-elevation bulk and the balance of the pair, so a pack that draws the gable against the neighbour is decided faster and refused less often than a DIY submission.

Across Badlesmere, Bexon and Borden - Chestnut Street, the hip-to-gable that goes through is the restrained one: the gable built to the original ridge rather than above it, materials matched so the extended end reads as part of the house, and — on a pair — the new wall sitting comfortably beside the neighbour's hip rather than overwhelming it. On the borough's victorian and earlier houses (31% of 22,440 homes), squaring one or both hips is what makes the whole loft usable, which is why it is nearly always drawn with a rear dormer behind.
The 22,440 homes here are 31% pre-1900, 7% 1955-1964, 5% 1965-1972, which is what sets the realistic roof and rear-projection options. We hold the gable to the ridge, detail the verge and the flank window to sit quietly, and present the gable and dormer as one roof alteration — so Swale Borough Council assesses a single coherent change to the roof rather than two competing ones.
We draw hip-to-gable lofts on the semi-detached and end-of-terrace streets across the borough. A few of the neighbourhoods where Swale hip-to-gables come up most often:

A hip-to-gable only applies where the roof is hipped — and what it gains depends on the house. This is how the cases compare.
| Roof / house type | Hip-to-gable route | What it gains | What Swale Borough Council checks |
|---|---|---|---|
| Hipped semi-detached | Full application, one gable | Full-width loft on the hipped side | Balance with the paired neighbour |
| Hipped end-terrace | Full application, one gable | Squares off the exposed end | Side elevation and street rhythm |
| Hipped detached | Full application, one or both ends | Loft across the whole roof | Bulk and the wider roofscape |
| Already gabled roof | Not needed — dormer only | Space via a rear dormer instead | Dormer volume and set-back |
In conservation areas such as Badlesmere and Bexon, the loss of a hip is resisted and a hip-to-gable is assessed on its effect on the protected roofscape.
A fixed process built around how Swale Borough Council validates and decides hip-to-gable applications — most drawings are submission-ready within seven days of survey.
Send us your Swale postcode and whether your roof is hipped one or both ends. We confirm your conservation and Article 4 status and score your odds against live Swale Borough Council decisions.
We measure the ridge and eaves, the hip geometry and — on a pair — the neighbour's roof, so the new gable can be drawn to the original ridge and balanced against the adjoining house.
Chartered designers develop the gable and its rear dormer to your brief, drawn to Swale Borough Council's roof-alteration guidance with the side elevation and neighbour relationship resolved on the page.
We submit the householder application, manage validation and case-officer queries, and revise the drawings free until Swale Borough Council issues its decision.
Yes. A hip-to-gable rebuilds the sloping hipped end of the roof as a vertical gable, and because that extends the roof it falls outside permitted development — so it always needs a full householder application to Swale Borough Council, whether or not your street is designated. It is usually submitted together with a rear dormer as a single roof-alteration application.
It replaces the roof's sloping hipped end with a flat gable wall built up to the ridge, turning the wasted triangle where the slope cuts in into full-height loft space across the width of the house. Swale's hipped semis and end-terraces suit it especially well, and it is nearly always paired with a rear dormer to open up the back of the roof too. Swale Borough Council is the decision-maker.
Yes, and a matching pair often reads better to Swale Borough Council than a single gable on one side, because it keeps the two houses balanced. Where only one owner converts, we draw the new gable carefully against the neighbour's retained hip so the officer can see the pair still works. The balance of the pair is one of the main things the council weighs.
Almost always. The gable opens up the side of the roof and a rear dormer opens up the back, and together they make the whole loft usable — so in Swale the two are typically drawn and submitted as one application to Swale Borough Council. Presenting them together means the council assesses a single coherent change to the roof rather than two separate alterations.
Usually, on a semi or end-terrace. The gable is built up off the flank, and the loft steelwork often bears on the party wall, so the Party Wall etc. Act applies and notice must be served before work starts — separately from Swale Borough Council's planning decision. We detail the junction on the drawings and flag the notice early so a surveyor can be appointed without delay.
We price each Swale hip-to-gable individually, because the roof geometry and whether it is one gable or two vary house to house, and send a fixed, no-obligation quote within one working day. It covers the full drawing pack — usually gable plus rear dormer — with free revisions until Swale Borough Council approves. Call 020 7864 7245 to start.
