Monkton & North Curry householder planning by the numbers

Somerset Council granted 94% of the householder planning decisions it made in its latest published year — 7 points above the 87% England-wide householder average. Monkton & North Curry contains Cheddon Fitzpaine, Hestercombe, North Curry conservation areas (Cheddon Fitzpaine designated 1977), 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.

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. In conservation areas such as Cheddon Fitzpaine, Hestercombe and North Curry those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Monkton & North Curry is determined against an 8-week statutory target.

Cheddon Fitzpaine (conservation area designated in 1977), Hestercombe (conservation area designated in 1998), North Curry (conservation area designated in 1970), West Monkton (conservation area designated in 1993), Durston (civil parish within Monkton & North Curry), North Curry (civil parish within Monkton & North Curry), Stoke St. Gregory (civil parish within Monkton & North Curry), Burrowbridge (civil parish within Monkton & North Curry), Creech St. Michael (civil parish within Monkton & North Curry) and Cheddon Fitzpaine (civil parish within Monkton & North Curry) — these are the Monkton & North Curry pockets our drawings cover most. Heritage designations here include Cheddon Fitzpaine, Hestercombe, North Curry and West Monkton. Somerset Council weighs each proposal against the adopted Somerset local plan and Somerset Council's design guidance for householder work, where the 5,570 homes here are 16% pre-1900, 12% 1965-1972, 7% 1993-1999, 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 shallow-pitched roofs and integral garages typical of that period's building, over Victorian and earlier houses (16% of 5,570 homes), late-1960s and early-1970s houses (12%) and 1990s estate houses (7%).

What actually constrains a project in Monkton & North Curry

Monkton & North Curry's designated heritage is specific, and it is the first thing we check against your address: Cheddon Fitzpaine (conservation area designated in 1977), Hestercombe (conservation area designated in 1998), North Curry (conservation area designated in 1970) and West Monkton (conservation area designated in 1993). Inside those boundaries permitted development is curtailed and Somerset 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, Monkton & North Curry takes in Durston, North Curry, Stoke St. Gregory, Burrowbridge, Creech St. Michael and Cheddon Fitzpaine. No Article 4 direction is recorded for Somerset Council, but Monkton & North Curry's 4 conservation areas still limit permitted development on those streets.

On stock, Monkton & North Curry is Victorian and earlier houses (16% of 5,570 homes), late-1960s and early-1970s houses (12%) and 1990s estate houses (7%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow-pitched roofs and integral garages typical of that period's building govern what a loft or rear projection can realistically be. Somerset Council decided 1,422 householder applications in the latest published year and granted 94%, with 74% issued inside the eight-week target. Those are the numbers our drawings are prepared against.

The full build-period split for Monkton & North Curry runs pre-1900 16% (910 homes), 1900-1918 0% (20 homes), 1919-1929 2% (90 homes), 1930-1939 3% (160 homes), 1945-1954 3% (170 homes), 1955-1964 6% (330 homes), 1965-1972 12% (650 homes), 1973-1982 6% (310 homes), 1983-1992 7% (370 homes), 1993-1999 7% (380 homes) and 2000-2008 4% (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.

Somerset Council also decides for Blackdown & Neroche, Blackmoor Vale, Brent, Bridgwater South, Bridgwater West, Brympton, Burnham on Sea North and Cannington, so a decision in Monkton & North Curry 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.

Extension plans built around Somerset Council's rules

Monkton & North Curry 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 (16% of 5,570 homes), late-1960s and early-1970s houses (12%) and 1990s estate houses (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. Somerset Council judges every one of them against the adopted Somerset local plan and Somerset Council's design guidance for householder work, 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. Monkton & North Curry contains Cheddon Fitzpaine, Hestercombe, North Curry conservation areas (Cheddon Fitzpaine designated 1977), 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.

Monkton & North Curry also protects whole streets — Cheddon Fitzpaine, Hestercombe, North Curry and West Monkton among them. No Article 4 direction is recorded for Somerset Council, but Monkton & North Curry's 4 conservation areas still limit permitted development on those streets. 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 Monkton & North Curry?

Plenty of Monkton & North Curry 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 Somerset 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 Cheddon Fitzpaine and Hestercombe, where the larger-home route and side extensions are not permitted development

Monkton & North Curry extension approval rates — live from council data

Below is Somerset Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Somerset Council granted 94% of its householder applications in the year to 31 March 2026, and Cheddon Fitzpaine 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 Monkton & North Curry

Across Cheddon Fitzpaine, Hestercombe and North Curry, 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 (16% of 5,570 homes), a side-return infill frequently pairs with it to square off the plan; on wider 1990s estate houses (7%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.

The 5,570 homes here are 16% pre-1900, 12% 1965-1972, 7% 1993-1999, 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 Somerset 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 Monkton & North Curry home?

The right extension in Monkton & North Curry 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 Somerset 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 Cheddon Fitzpaine and Hestercombe and Article 4 directions can remove permitted-development rights.

Frequently asked questions

Do I need planning permission to extend my house in Monkton & North Curry?

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 Monkton & North Curry you will need to apply to Somerset 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 Cheddon Fitzpaine and Hestercombe.

How deep can a single-storey rear extension go in Monkton & North Curry 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 Somerset Council and a neighbour-consultation period, and it does not apply on designated land such as Monkton & North Curry's conservation areas. We confirm which route your property qualifies for before drawing.

Can I build a double-storey extension in Monkton & North Curry?

Two-storey and double-storey extensions almost always need a full householder application to Somerset 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 Monkton & North Curry address specifically.

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

A householder planning application in Monkton & North Curry 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. Somerset Council is the decision-maker.

Will my extension in Monkton & North Curry 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 Somerset Council's building control or an approved inspector can sign the work off. This applies to your Monkton & North Curry address specifically.

How much do extension plans in Monkton & North Curry cost?

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