Hip-to-gable drawings for Wigan 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 Wigan Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Wigan Council granted 89% of the householder planning decisions it made in its latest published year — 2 points above the 87% England-wide householder average. A large share of the borough is Green Belt, so extension and outbuilding scale is tightly held on affected plots away from the urban cores, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910), interwar (1918–1939) 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 Wigan Council needs a full application. Wigan carries at least one Article 4 direction, and conservation areas including Wigan Town Centre, Wigan Pier and Standish remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Wigan is determined against an 8-week statutory target.
Standish (affluent commuter village with a conservation-area core mixing stone and brick with modern estates), Leigh (former cotton and mining town with canal heritage, dense terraces and a town-centre conservation area), Ashton-in-Makerfield (southern coalfield town of brick terraces and interwar suburban growth), Hindley (mining township of terraced streets with a town-centre conservation area), Tyldesley (former mill and mining town of brick terraces with a town-centre conservation area) and Haigh (semi-rural estate village adjoining Haigh Woodland Park with protected historic character) — these are the Wigan pockets our drawings cover most. Heritage designations here include Wigan Town Centre, Wigan Pier, Standish, Haigh Village, Leigh Town Centre and Tyldesley Town Centre. Wigan Council weighs each proposal against Places for Everyone (the Greater Manchester joint plan, effective March 2024) alongside the Wigan Local Plan Core Strategy and the emerging district Local Plan, where the former coalfield legacy of the Wigan Flashes and low-lying mossland brings ground-stability, contamination and ecology constraints to development sites. Converted terraced flats occur across the town centres of Wigan and Leigh, and those units carry no householder permitted-development rights.. On roofs the borough is Welsh slate on the Victorian and Edwardian brick terraces and interlocking concrete tile on the interwar and post-war semis, over Victorian and Edwardian coalfield and millworkers' red-brick terraces, interwar semis and council-estate housing and older stone cores in the estate villages.
The hip-to-gable is the semi's loft, and Wigan has the stock that needs it — the borough runs to Victorian and Edwardian coalfield and millworkers' red-brick terraces, interwar semis and council-estate housing and older stone cores in the estate villages, 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. Wigan Council judges the scheme against Places for Everyone (the Greater Manchester joint plan, effective March 2024) alongside the Wigan Local Plan Core Strategy and the emerging district Local Plan, 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. A large share of the borough is Green Belt, so extension and outbuilding scale is tightly held on affected plots away from the urban cores, and on a paired roof that is precisely the test a hip-to-gable has to pass.
Where Wigan's streets are designated — Wigan Town Centre, Wigan Pier, Standish, Haigh Village, Leigh Town Centre and Tyldesley Town Centre among them — a hip-to-gable is scrutinised hard, because losing a hip changes the roofscape the area is protected for. Wigan's borough-wide Article 4 direction, in force from August 2025, removes permitted-development rights for the change of use from a house (C3) to a small HMO (C4), so all new HMOs now need planning permission, and localised conservation-area directions add further householder controls. We check the designation before the gable is drawn.
A hip-to-gable in Wigan 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 Wigan 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 Wigan Council's officers check first — and submit a validation-complete householder application, usually with the rear dormer on the same drawings.
Below is Wigan Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Wigan approves close to nine in ten planning applications, with its extensive Green Belt, former-coalfield ground conditions and canal-side conservation areas the main constraints on householder schemes. 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 Standish, Leigh and Ashton-in-Makerfield, 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 edwardian coalfield and millworkers' red-brick terraces, 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 former coalfield legacy of the Wigan Flashes and low-lying mossland brings ground-stability, contamination and ecology constraints to development sites. 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 Wigan 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 Wigan 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 Wigan 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 Wigan Town Centre and Wigan Pier, 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 Wigan Council validates and decides hip-to-gable applications — most drawings are submission-ready within seven days of survey.
Send us your Wigan 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 Wigan 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 Wigan 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 Wigan 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 Wigan 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. Wigan'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. Wigan Council is the decision-maker.
Yes, and a matching pair often reads better to Wigan 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 Wigan the two are typically drawn and submitted as one application to Wigan 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 Wigan 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 Wigan 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 Wigan Council approves. Call 020 7864 7245 to start.
