Hip-to-gable drawings for Wandsworth 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 Wandsworth Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Wandsworth Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. Side returns, mansards and dormers are judged in centimetres against the party wall and shared roofline, 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. Wandsworth carries at least one Article 4 direction, and conservation areas including Wandsworth Common, Nightingale Triangle and Tonsleys remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Wandsworth is determined against an 8-week statutory target.
Battersea (Victorian terraces and mansion flats near the park), Balham (Edwardian terraces around the Nightingale Triangle), Tooting (long Victorian terraces off the high road), Putney (Edwardian villas and riverside streets), Earlsfield (compact Victorian terraces between the commons) and Southfields (the Magdalen Park grid of Edwardian houses) — these are the Wandsworth pockets our drawings cover most. Heritage designations here include Wandsworth Common, Nightingale Triangle, Tonsleys, Magdalen Park and Battersea Park. Wandsworth Council weighs each proposal against Wandsworth Local Plan and the borough's Housing and Basements SPDs, where the borough applies detailed basement-development policies on top of the usual tests. Much of Battersea and Balham is converted flats and maisonettes, which carry no householder permitted-development rights.. On roofs the borough is butterfly / valley roofs on the terraces and pitched roofs on the villas, over Victorian terraces, Edwardian mansion flats and Putney and Wandsworth villas.
The hip-to-gable is the semi's loft, and Wandsworth has the stock that needs it — the borough runs to Victorian terraces, Edwardian mansion flats and Putney and Wandsworth villas, 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. Wandsworth Council judges the scheme against Wandsworth Local Plan and the borough's Housing and Basements SPDs, 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. Side returns, mansards and dormers are judged in centimetres against the party wall and shared roofline, and on a paired roof that is precisely the test a hip-to-gable has to pass.
Where Wandsworth's streets are designated — Wandsworth Common, Nightingale Triangle, Tonsleys, Magdalen Park and Battersea Park among them — a hip-to-gable is scrutinised hard, because losing a hip changes the roofscape the area is protected for. Several Wandsworth conservation areas carry Article 4 directions, and the borough's dense conservation coverage means many terraced streets need a full application for works that would be PD elsewhere. We check the designation before the gable is drawn.
A hip-to-gable in Wandsworth 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 Wandsworth 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 Wandsworth Council's officers check first — and submit a validation-complete householder application, usually with the rear dormer on the same drawings.
Below is Wandsworth Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Wandsworth grants a healthy share of householder applications, but its uniform Victorian terraces mean side returns and roof alterations are assessed in centimetres against the neighbours. 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 Battersea, Balham and Tooting, 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 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 borough applies detailed basement-development policies on top of the usual tests. 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 Wandsworth 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 Wandsworth hip-to-gables come up most often:
Hip-to-gable loft drawings for Battersea's Victorian terraces and mansion flats near the park — ridge-matched, pair-balanced and drawn to Wandsworth Council's guidance.

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 Wandsworth 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 Wandsworth Common and Nightingale Triangle, 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 Wandsworth Council validates and decides hip-to-gable applications — most drawings are submission-ready within seven days of survey.
Send us your Wandsworth 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 Wandsworth 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 Wandsworth 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 Wandsworth 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 Wandsworth 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. Wandsworth'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. Wandsworth Council is the decision-maker.
Yes, and a matching pair often reads better to Wandsworth 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 Wandsworth the two are typically drawn and submitted as one application to Wandsworth 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 Wandsworth 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 Wandsworth 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 Wandsworth Council approves. Call 020 7864 7245 to start.
