Hip-to-gable drawings for Glen 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 Harborough District Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Harborough 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. Glen contains Gaulby, Illston on the Hill, Kings Norton conservation areas (Gaulby designated 1994), 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 Harborough District Council needs a full application. In conservation areas such as Gaulby, Illston on the Hill and Kings Norton those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Glen is determined against an 8-week statutory target.
Gaulby (conservation area designated in 1994), Illston on the Hill (conservation area designated in 1994), Kings Norton (conservation area designated in 1994), Burton Overy (civil parish within Glen), Gaulby (civil parish within Glen), Great Glen (civil parish within Glen), Illston on the Hill (civil parish within Glen), King's Norton (civil parish within Glen) and Little Stretton (civil parish within Glen) — these are the Glen pockets our drawings cover most. Heritage designations here include Gaulby, Illston on the Hill and Kings Norton. Harborough District Council weighs each proposal against Harborough District Council's development plan and the design policies it applies to householder applications, where the 2,430 homes here are 16% 1965-1972, 12% pre-1900, 9% 1955-1964, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow-pitched roofs and integral garages typical of that period's building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, over late-1960s and early-1970s houses (16% of 2,430 homes), Victorian and earlier houses (12%) and late-1950s and early-1960s houses (9%).
Heritage designation is the single biggest variable in Glen, and it is address-specific: Gaulby (conservation area designated in 1994), Illston on the Hill (conservation area designated in 1994) and Kings Norton (conservation area designated in 1994). Inside those boundaries permitted development is curtailed and Harborough 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, Glen takes in Burton Overy, Gaulby, Great Glen, Illston on the Hill, King's Norton and Little Stretton. No Article 4 direction is recorded for Harborough District Council, but Glen's 3 conservation areas still limit permitted development on those streets.
On stock, Glen is late-1960s and early-1970s houses (16% of 2,430 homes), Victorian and earlier houses (12%) and late-1950s and early-1960s houses (9%) — which is why shallow-pitched roofs and integral garages typical of that period's building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building govern what a loft or rear projection can realistically be. Harborough District Council decided 439 householder applications in the latest published year and granted 92%, with 51% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Glen runs pre-1900 12% (290 homes), 1900-1918 2% (50 homes), 1919-1929 1% (30 homes), 1930-1939 1% (30 homes), 1945-1954 4% (90 homes), 1955-1964 9% (230 homes), 1965-1972 16% (400 homes), 1973-1982 8% (190 homes), 1983-1992 8% (190 homes), 1993-1999 5% (110 homes) and 2000-2008 8% (200 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.
Harborough District Council also decides for Billesdon & Tilton, Bosworth, Dunton, Fleckney, Kibworths, Lubenham, Misterton and Nevill, so a decision in Glen 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 Glen has the stock that needs it — the borough runs to late-1960s and early-1970s houses (16% of 2,430 homes), Victorian and earlier houses (12%) and late-1950s and early-1960s houses (9%), 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. Harborough District Council judges the scheme against Harborough District 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. Glen contains Gaulby, Illston on the Hill, Kings Norton conservation areas (Gaulby designated 1994), 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 Glen's streets are designated — Gaulby, Illston on the Hill and Kings Norton 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 Harborough District Council, but Glen's 3 conservation areas still limit permitted development on those streets. We check the designation before the gable is drawn.
A hip-to-gable in Glen 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 Harborough District 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 Harborough District Council's officers check first — and submit a validation-complete householder application, usually with the rear dormer on the same drawings.
Below is Harborough District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Harborough District Council granted 92% of its householder applications in the year to 31 March 2026, and Gaulby 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 Gaulby, Illston on the Hill and Kings Norton, 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 late-1960s and early-1970s houses (16% of 2,430 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 2,430 homes here are 16% 1965-1972, 12% pre-1900, 9% 1955-1964, 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 Harborough District 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 Glen 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 Harborough District 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 Gaulby and Illston on the Hill, 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 Harborough District Council validates and decides hip-to-gable applications — most drawings are submission-ready within seven days of survey.
Send us your Glen 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 Harborough District 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 Harborough District 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 Harborough District 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 Harborough District 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 Glen 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. Glen'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. Harborough District Council is the decision-maker.
Yes, and a matching pair often reads better to Harborough District 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 Glen 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 Glen the two are typically drawn and submitted as one application to Harborough District 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 Harborough District 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 Glen address specifically.
We price each Glen 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 Harborough District Council approves. Call 020 7864 7245 to start.
