Tormohun householder planning by the numbers

Torbay Council granted 90% of the householder planning decisions it made in its latest published year — 3 points above the 87% England-wide householder average. Tormohun contains Abbey Road, Belgravia, Tormohun conservation areas (Abbey Road designated 1989), 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) housing stock sets the design brief on most streets.

Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. Tormohun carries at least one Article 4 direction, and conservation areas including Abbey Road, Belgravia and Tormohun remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Tormohun is determined against an 8-week statutory target.

Abbey Road (conservation area designated in 1989), Belgravia (conservation area designated in 1988), Tormohun (conservation area designated in 1989), Torquay Harbour (conservation area designated in 1975), Torre (conservation area designated in 1989) and Upton (conservation area designated in 1989) — these are the Tormohun pockets our drawings cover most. Heritage designations here include Abbey Road, Belgravia, Tormohun, Torquay Harbour, Torre and Upton. Torbay Council weighs each proposal against Torbay Council's adopted local plan and its householder design guidance, where the 7,350 homes here are 55% pre-1900, 8% 1983-1992, 7% 2000-2008, 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 (55% of 7,350 homes), 1980s estate houses (8%) and 2000s houses and apartments (7%).

What actually constrains a project in Tormohun

Tormohun's designated heritage is specific, and it is the first thing we check against your address: Abbey Road (conservation area designated in 1989), Belgravia (conservation area designated in 1988), Tormohun (conservation area designated in 1989), Torquay Harbour (conservation area designated in 1975), Torre (conservation area designated in 1989) and Upton (conservation area designated in 1989). Inside those boundaries permitted development is curtailed and Torbay 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.

Torbay Council has 2 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 Tormohun.

On stock, Tormohun is Victorian and earlier houses (55% of 7,350 homes), 1980s estate houses (8%) and 2000s houses and apartments (7%) — 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. Torbay Council decided 266 householder applications in the latest published year and granted 90%, with 37% issued inside the eight-week target. Those are the numbers our drawings are prepared against.

The full build-period split for Tormohun runs pre-1900 55% (4,010 homes), 1900-1918 2% (160 homes), 1919-1929 3% (240 homes), 1930-1939 3% (200 homes), 1945-1954 1% (80 homes), 1955-1964 3% (240 homes), 1965-1972 4% (290 homes), 1973-1982 6% (460 homes), 1983-1992 8% (620 homes), 1993-1999 3% (220 homes) and 2000-2008 7% (510 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.

Torbay Council also decides for Barton with Watcombe, Churston with Galmpton, Roundham with Hyde, St Marychurch and Wellswood, so a decision in Tormohun 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 Churston and Polsham. 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.

Extension plans built around Torbay Council's rules

Tormohun homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from Victorian and earlier houses (55% of 7,350 homes), 1980s estate houses (8%) and 2000s houses and apartments (7%), so a Victorian terrace usually wants a rear or side-return infill, while an interwar semi has room for a wider single-storey wrap or a two-storey side addition. Torbay Council judges every one of them against Torbay Council's adopted local plan and its householder design guidance, weighing footprint, height and the impact on the house next door before it looks at the elevations.

That is why the drawings decide the outcome. We set the extension depth against the permitted-development limits precisely, keep the eaves and ridge within the allowances, and plot the 45-degree daylight lines to the neighbours' windows so the case officer can see the amenity test is passed. Tormohun contains Abbey Road, Belgravia, Tormohun conservation areas (Abbey Road designated 1989), so materials, fenestration and roof form are assessed against the appraisal, so we design around it from the first sketch rather than discover it at validation.

Tormohun also protects whole streets — Abbey Road, Belgravia, Tormohun, Torquay Harbour, Torre and Upton among them. Torbay Council has 2 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 Tormohun. On designated land the larger-home extension route and most side extensions stop being permitted development, so we confirm your address against those layers before drawing a line.

Do I need planning permission to extend my house in Tormohun?

Plenty of Tormohun extensions are permitted development and need no planning application — a single-storey rear extension within the depth and height limits is the common case. You will normally need to apply to Torbay Council if any of these apply:

  • The single-storey rear extension is deeper than 3 metres on a terrace or semi, or 4 metres on a detached house (6m/8m needs prior approval under the larger-home scheme)
  • It is a two-storey or double-storey extension, or the rear extension is higher than 4 metres
  • A side extension is wider than half the original house, or more than one storey
  • Any part projects forward of the principal (front) elevation, or the extension covers more than half the garden
  • Your home is in a conservation area such as Abbey Road and Belgravia, where the larger-home route and side extensions are not permitted development
  • An Article 4 direction applies to your street — Tormohun has several, so this is checked first

Tormohun extension approval rates — live from council data

Below is Torbay Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Torbay Council granted 90% of its householder applications in the year to 31 March 2026, and Abbey Road shapes what is approved here. A complete, policy-literate extension pack anticipates those pressure points before submission, which is why professionally drawn applications are decided faster and refused less often than DIY ones.

Which extensions get approved in Tormohun

Across Abbey Road, Belgravia and Tormohun, the extension that lands most often is the single-storey rear addition — a glazed kitchen-diner across the back of the house, kept within the permitted-development depth or taken to a full application where the ground floor wants more. On the borough's victorian and earlier houses (55% of 7,350 homes), a side-return infill frequently pairs with it to square off the plan; on wider 2000s houses and apartments (7%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.

The 7,350 homes here are 55% pre-1900, 8% 1983-1992, 7% 2000-2008, which is what sets the realistic roof and rear-projection options. We size the extension to the amenity and daylight tests, match the roof and materials to the host house, and keep enough garden to satisfy Torbay Council's space standards — so the scheme answers the borough's questions before an objection can raise them. Where permitted-development rights are used up or removed, we prepare the householder application to the council's extension design guidance instead.

Which extension suits your Tormohun home?

The right extension in Tormohun depends on your house type and how much garden you can give up. This is how the main options compare on planning route and what they add.

Extension typePermitted development?What it addsWhat Torbay Council checks
Single-storey rearOften, within 3m/4m depth (6m/8m via prior approval)Bigger kitchen-diner across the backDepth, height, neighbour daylight (45°)
Side-return infillSometimes, if within width and height limitsSquares off an L-shaped ground floorWidth vs the original house, glazing to boundary
Two-storey rear/sideNo — full applicationExtra bedroom or bathroom aboveBulk, overlooking, 7m rear-boundary gap
Wraparound (rear + side)No — full applicationWhole-width open-plan ground floorCombined footprint and garden retained

Route depends on your street — conservation areas such as Abbey Road and Belgravia and Article 4 directions can remove permitted-development rights.

Four steps to an approved Tormohun extension

A fixed process built around how Torbay Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.

  1. 1

    Free approval check

  2. 2

    Measured survey

    We measure the existing footprint, floor and eaves levels, boundary distances and the neighbours' window positions — the numbers the depth limits and daylight tests depend on.

  3. 3

    Extension design & drawings

    Chartered designers develop the single-storey, two-storey or side extension to your brief, drawn inside the permitted-development limits or to Torbay Council's extension design guidance.

  4. 4

    Submission & follow-through

    We submit the certificate, prior-approval notice or application, manage validation and case-officer queries, and revise the drawings free until Torbay Council issues its decision.

Frequently asked questions

Do I need planning permission to extend my house in Tormohun?

Not always. A single-storey rear extension up to 3 metres deep on a terrace or semi, or 4 metres on a detached house, and no higher than 4 metres, is usually permitted development. In Tormohun you will need to apply to Torbay Council for two-storey extensions, side extensions wider than half the house, anything forward of the front wall, deeper rear extensions under the larger-home prior-approval route, and any extension in a conservation area such as Abbey Road and Belgravia.

How deep can a single-storey rear extension go in Tormohun without planning permission?

Standard permitted development allows 3 metres on a terraced or semi-detached house and 4 metres on a detached one. The larger-home extension scheme can double that to 6 or 8 metres, but it needs a prior-approval notification to Torbay Council and a neighbour-consultation period, and it does not apply on designated land such as Tormohun's conservation areas. We confirm which route your property qualifies for before drawing.

Can I build a double-storey extension in Tormohun?

Two-storey and double-storey extensions almost always need a full householder application to Torbay Council, because they fall outside permitted development on most homes. The council looks closely at bulk, overlooking of neighbours and the 7-metre gap a two-storey rear extension must keep from the rear boundary. We design to those tests and show the daylight and privacy angles on the drawings. This applies to your Tormohun address specifically.

How long does Torbay Council take to decide an extension application?

A householder planning application in Tormohun runs to a statutory eight-week target, a larger-home prior-approval notification to around six weeks including the neighbour-consultation period, and a lawful development certificate to eight weeks. Incomplete submissions stall at validation, so we submit a complete pack and manage officer queries to keep the decision on schedule. Torbay Council is the decision-maker.

Will my extension in Tormohun need building regulations approval as well as planning?

Yes — planning permission and building regulations are separate consents, and almost every extension needs both. Planning governs whether you can build it; building control governs how it is built, covering structure, insulation, drainage and fire safety. We prepare the building-regulations drawings alongside the planning set so Torbay Council's building control or an approved inspector can sign the work off. This applies to your Tormohun address specifically.

How much do extension plans in Tormohun cost?

Every house and brief is different, so we price each Tormohun extension individually and send a fixed, no-obligation quote back within one working day. It covers the full drawing pack with free revisions until Torbay Council approves, and we tell you upfront whether your extension qualifies as permitted development.
