Hip-to-gable drawings for Bassett 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 Southampton City Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Southampton City Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. A lower HMO concentration cap protects Bassett's family-housing balance, so conversions face firm resistance, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), 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 Southampton City Council needs a full application. Bassett carries at least one Article 4 direction, and conservation areas including Bassett Green Village and The Avenue remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Bassett is determined against an 8-week statutory target.
Bassett (interwar and postwar detached houses on large plots near the common), Bassett Green Village (historic estate cottages designated as a conservation area in 1977), The Avenue (large villas lining the tree-lined northern approach to the city), Bassett Green (postwar and later suburban housing towards the university), Chilworth border (low-density detached homes on the city's northern edge) and Glen Eyre (student halls and suburban housing near the campus) — these are the Bassett pockets our drawings cover most. Heritage designations here include Bassett Green Village and The Avenue. Southampton City Council weighs each proposal against the Southampton City Local Plan / Core Strategy, where the estate-cottage character of Bassett Green Village restricts alterations to roofs, boundaries and frontages. On roofs the borough is hipped roofs on the interwar semis and gabled roofs on the detached and older stock, over interwar and postwar detached and semi-detached houses on generous plots, Victorian estate cottages in Bassett Green Village and substantial villas along The Avenue.
The hip-to-gable is the semi's loft, and Bassett has the stock that needs it — the borough runs to interwar and postwar detached and semi-detached houses on generous plots, Victorian estate cottages in Bassett Green Village and substantial villas along The Avenue, 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. Southampton City Council judges the scheme against the Southampton City Local Plan / Core Strategy, 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 lower HMO concentration cap protects Bassett's family-housing balance, so conversions face firm resistance, and on a paired roof that is precisely the test a hip-to-gable has to pass.
Where Bassett's streets are designated — Bassett Green Village and The Avenue among them — a hip-to-gable is scrutinised hard, because losing a hip changes the roofscape the area is protected for. Bassett is a leafier suburb but still falls within Southampton's city-wide HMO Article 4 direction adopted in March 2012, and a lower HMO concentration cap has been applied around Bassett and Swaythling to protect its family-housing character. We check the designation before the gable is drawn.
A hip-to-gable in Bassett 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 Southampton City 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 Southampton City Council's officers check first — and submit a validation-complete householder application, usually with the rear dormer on the same drawings.
Below is Southampton City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Southampton approves around 92% of applications, and in Bassett the priority is guarding a low-density, family-housing character against HMO and infill pressure. 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 Bassett, Bassett Green Village and The Avenue, 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 interwar and postwar detached and semi-detached houses on generous plots, 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 estate-cottage character of Bassett Green Village restricts alterations to roofs, boundaries and frontages. 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 Southampton City 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 Bassett 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 Southampton City 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 Bassett Green Village and The Avenue, 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 Southampton City Council validates and decides hip-to-gable applications — most drawings are submission-ready within seven days of survey.
Send us your Bassett 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 Southampton City 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 Southampton City 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 Southampton City 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 Southampton City 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 Bassett 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. Bassett'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. Southampton City Council is the decision-maker.
Yes, and a matching pair often reads better to Southampton City 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 Bassett 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 Bassett the two are typically drawn and submitted as one application to Southampton City 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 Southampton City 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 Bassett address specifically.
We price each Bassett 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 Southampton City Council approves. Call 020 7864 7245 to start.
