Hip-to-gable drawings for Marlborough West 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 Wiltshire Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Wiltshire Council granted 96% of the householder planning decisions it made in its latest published year — 9 points above the 87% England-wide householder average. Marlborough West contains AVEBURY, EAST KENNETT, LOCKERIDGE conservation areas (AVEBURY 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 interwar (1918–1939) 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 Wiltshire Council needs a full application. Marlborough West carries at least one Article 4 direction, and conservation areas including AVEBURY, EAST KENNETT and LOCKERIDGE remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Marlborough West is determined against an 8-week statutory target.
AVEBURY (conservation area designated in 1975), EAST KENNETT (conservation area designated in 1974), LOCKERIDGE (conservation area designated in 1985), MANTON (conservation area designated in 1985), MARLBOROUGH (conservation area designated in 1971), WEST KENNETT (conservation area designated in 1975), Avebury (civil parish within Marlborough West), Berwick Bassett (civil parish within Marlborough West), Marlborough (civil parish within Marlborough West), East Kennett (civil parish within Marlborough West), Fyfield (civil parish within Marlborough West) and West Overton (civil parish within Marlborough West) — these are the Marlborough West pockets our drawings cover most. Heritage designations here include AVEBURY, EAST KENNETT, LOCKERIDGE, MANTON, MARLBOROUGH and WEST KENNETT. Wiltshire Council weighs each proposal against Wiltshire Council's development plan and the design policies it applies to householder applications, where the 2,840 homes here are 24% pre-1900, 18% 1983-1992, 8% 1930-1939, 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 1980s building, over Victorian and earlier houses (24% of 2,840 homes), 1980s estate houses (18%) and 1930s semi-detached and detached houses (8%).
Heritage designation is the single biggest variable in Marlborough West, and it is address-specific: AVEBURY (conservation area designated in 1975), EAST KENNETT (conservation area designated in 1974), LOCKERIDGE (conservation area designated in 1985), MANTON (conservation area designated in 1985), MARLBOROUGH (conservation area designated in 1971) and WEST KENNETT (conservation area designated in 1975). Inside those boundaries permitted development is curtailed and Wiltshire 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, Marlborough West takes in Avebury, Berwick Bassett, Marlborough, East Kennett, Fyfield and West Overton. Wiltshire Council has 48 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in Marlborough West.
On stock, Marlborough West is Victorian and earlier houses (24% of 2,840 homes), 1980s estate houses (18%) and 1930s semi-detached and detached houses (8%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 1980s building govern what a loft or rear projection can realistically be. Wiltshire Council decided 1,779 householder applications in the latest published year and granted 96%, with 53% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Marlborough West runs pre-1900 24% (680 homes), 1900-1918 6% (160 homes), 1919-1929 0% (10 homes), 1930-1939 8% (220 homes), 1945-1954 2% (50 homes), 1955-1964 5% (140 homes), 1965-1972 7% (200 homes), 1973-1982 5% (140 homes), 1983-1992 18% (510 homes), 1993-1999 4% (110 homes) and 2000-2008 6% (160 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.
Wiltshire Council also decides for Aldbourne & Ramsbury, Amesbury West, Avon Valley, Box & Colerne, By Brook, Corsham Ladbrook, Corsham Pickwick and Corsham Without, so a decision in Marlborough West 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 Ashley, Avebury, Baydon 1 and Baydon 2. 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 Marlborough West has the stock that needs it — the borough runs to Victorian and earlier houses (24% of 2,840 homes), 1980s estate houses (18%) and 1930s semi-detached and detached houses (8%), 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. Wiltshire Council judges the scheme against Wiltshire Council's development plan and the design policies it applies to householder applications, 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. Marlborough West contains AVEBURY, EAST KENNETT, LOCKERIDGE conservation areas (AVEBURY 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 Marlborough West's streets are designated — AVEBURY, EAST KENNETT, LOCKERIDGE, MANTON, MARLBOROUGH and WEST KENNETT among them — a hip-to-gable is scrutinised hard, because losing a hip changes the roofscape the area is protected for. Wiltshire Council has 48 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in Marlborough West. We check the designation before the gable is drawn.
A hip-to-gable in Marlborough West 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 Wiltshire 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 Wiltshire Council's officers check first — and submit a validation-complete householder application, usually with the rear dormer on the same drawings.
Below is Wiltshire Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Wiltshire Council granted 96% of its householder applications in the year to 31 March 2026, and AVEBURY 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 AVEBURY, EAST KENNETT and LOCKERIDGE, 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 (24% of 2,840 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 2,840 homes here are 24% pre-1900, 18% 1983-1992, 8% 1930-1939, 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 Wiltshire 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 Marlborough West 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 Wiltshire 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 AVEBURY and EAST KENNETT, 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 Wiltshire Council validates and decides hip-to-gable applications — most drawings are submission-ready within seven days of survey.
Send us your Marlborough West 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 Wiltshire 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 Wiltshire 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 Wiltshire 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 Wiltshire 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 Marlborough West 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. Marlborough West'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. Wiltshire Council is the decision-maker.
Yes, and a matching pair often reads better to Wiltshire 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 Marlborough West 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 Marlborough West the two are typically drawn and submitted as one application to Wiltshire 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 Wiltshire 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 Marlborough West address specifically.
We price each Marlborough West 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 Wiltshire Council approves. Call 020 7864 7245 to start.
