Hip-to-gable drawings for Town 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 Gravesham Borough Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Gravesham Borough Council granted 78% of the householder planning decisions it made in its latest published year — 9 points below the 87% England-wide householder average. Town contains Harmer Street, Gravesend Conservation Area, High Street & Queen Street, Gravesend Conservation Area, King Street, Gravesend Conservation Area conservation areas (Harmer Street, Gravesend Conservation Area 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) and Edwardian (1901–1910) 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. In conservation areas such as Harmer Street, Gravesend Conservation Area, High Street & Queen Street, Gravesend Conservation Area and King Street, Gravesend Conservation Area those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Town is determined against an 8-week statutory target.
Harmer Street, Gravesend (conservation area designated in 1975), High Street & Queen Street, Gravesend (conservation area designated in 1975), King Street, Gravesend (conservation area designated in 1980), Milton Place, Gravesend (conservation area designated in 1990), Riverside, Gravesend (conservation area designated in 1980) and Upper Windmill Street, Gravesend (conservation area designated in 1980) — these are the Town pockets our drawings cover most. Heritage designations here include Harmer Street, Gravesend Conservation Area, High Street & Queen Street, Gravesend Conservation Area, King Street, Gravesend Conservation Area, Milton Place, Gravesend Conservation Area, Riverside, Gravesend Conservation Area and Upper Windmill Street, Gravesend Conservation Area. Gravesham Borough Council weighs each proposal against Gravesham Borough Council's adopted local plan and its householder design guidance, where the 5,810 homes here are 34% pre-1900, 13% 2000-2008, 12% 1900-1918, 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 trussed-rafter roofs typical of 2000s building, over Victorian and earlier houses (34% of 5,810 homes), 2000s houses and apartments (13%) and Edwardian houses (12%).
What is permitted in Town turns on designation first, so that is where we start: Harmer Street, Gravesend (conservation area designated in 1975), High Street & Queen Street, Gravesend (conservation area designated in 1975), King Street, Gravesend (conservation area designated in 1980), Milton Place, Gravesend (conservation area designated in 1990), Riverside, Gravesend (conservation area designated in 1980) and Upper Windmill Street, Gravesend (conservation area designated in 1980). Inside those boundaries permitted development is curtailed and Gravesham 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.
No Article 4 direction is recorded for Gravesham Borough Council, but Town's 6 conservation areas still limit permitted development on those streets.
On stock, Town is Victorian and earlier houses (34% of 5,810 homes), 2000s houses and apartments (13%) and Edwardian houses (12%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 2000s building govern what a loft or rear projection can realistically be. Gravesham Borough Council decided 400 householder applications in the latest published year and granted 78%, with 72% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Town runs pre-1900 34% (1,960 homes), 1900-1918 12% (710 homes), 1919-1929 2% (90 homes), 1930-1939 2% (110 homes), 1945-1954 1% (30 homes), 1955-1964 6% (360 homes), 1965-1972 6% (320 homes), 1973-1982 8% (460 homes), 1983-1992 7% (430 homes), 1993-1999 3% (170 homes) and 2000-2008 13% (750 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.
Gravesham Borough Council also decides for Higham & Shorne, Meopham North, Meopham South & Vigo and Pelham, so a decision in Town 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 hip-to-gable is the semi's loft, and Town has the stock that needs it — the borough runs to Victorian and earlier houses (34% of 5,810 homes), 2000s houses and apartments (13%) and Edwardian houses (12%), 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. Gravesham Borough Council judges the scheme against Gravesham 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. Town contains Harmer Street, Gravesend Conservation Area, High Street & Queen Street, Gravesend Conservation Area, King Street, Gravesend Conservation Area conservation areas (Harmer Street, Gravesend Conservation Area designated 1975), 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 Town's streets are designated — Harmer Street, Gravesend Conservation Area, High Street & Queen Street, Gravesend Conservation Area, King Street, Gravesend Conservation Area, Milton Place, Gravesend Conservation Area, Riverside, Gravesend Conservation Area and Upper Windmill Street, Gravesend Conservation Area among them — a hip-to-gable is scrutinised hard, because losing a hip changes the roofscape the area is protected for. No Article 4 direction is recorded for Gravesham Borough Council, but Town's 6 conservation areas still limit permitted development on those streets. We check the designation before the gable is drawn.
A hip-to-gable in Town 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 Gravesham 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 Gravesham Borough Council's officers check first — and submit a validation-complete householder application, usually with the rear dormer on the same drawings.
Below is Gravesham Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Gravesham Borough Council granted 78% of its householder applications in the year to 31 March 2026, and Harmer Street, Gravesend Conservation Area shapes what is approved here. 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 Harmer Street, Gravesend, High Street & Queen Street, Gravesend and King Street, Gravesend, 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 (34% of 5,810 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 5,810 homes here are 34% pre-1900, 13% 2000-2008, 12% 1900-1918, 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 Gravesham 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 Town 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 Gravesham 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 Harmer Street, Gravesend Conservation Area and High Street & Queen Street, Gravesend Conservation Area, 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 Gravesham Borough Council validates and decides hip-to-gable applications — most drawings are submission-ready within seven days of survey.
Send us your Town 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 Gravesham 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 Gravesham 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 Gravesham 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 Gravesham Borough Council, whether or not your street is designated. It is usually submitted together with a rear dormer as a single roof-alteration application. This applies to your Town address specifically.
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. Town'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. Gravesham Borough Council is the decision-maker.
Yes, and a matching pair often reads better to Gravesham 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. This applies to your Town address specifically.
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 Town the two are typically drawn and submitted as one application to Gravesham 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 Gravesham 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. This applies to your Town address specifically.
We price each Town 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 Gravesham Borough Council approves. Call 020 7864 7245 to start.
