Crown planning decisions and design rules

East Staffordshire Borough Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. Crown contains Marchington, Newborough conservation areas, 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.

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. In conservation areas such as Marchington and Newborough those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Crown is determined against an 8-week statutory target.

Marchington (designated conservation area), Newborough (designated conservation area), Marchington (civil parish within Crown), Newborough (civil parish within Crown), Draycott in the Clay (civil parish within Crown) and Hanbury (civil parish within Crown) — these are the Crown pockets our drawings cover most. Heritage designations here include Marchington and Newborough. East Staffordshire Borough Council weighs each proposal against the adopted East Staffordshire local plan and East Staffordshire Borough Council's design guidance for householder work, where the 1,110 homes here are 29% pre-1900, 13% 1955-1964, 11% 1965-1972, 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 gabled roofs typical of that period's building, over Victorian and earlier houses (29% of 1,110 homes), late-1950s and early-1960s houses (13%) and late-1960s and early-1970s houses (11%).

Why a Crown scheme is judged on Crown terms

What is permitted in Crown turns on designation first, so that is where we start: Marchington (designated conservation area) and Newborough (designated conservation area). Inside those boundaries permitted development is curtailed and East Staffordshire Borough 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, Crown takes in Marchington, Newborough, Draycott in the Clay and Hanbury. No Article 4 direction is recorded for East Staffordshire Borough Council, but Crown's 2 conservation areas still limit permitted development on those streets.

On stock, Crown is Victorian and earlier houses (29% of 1,110 homes), late-1950s and early-1960s houses (13%) and late-1960s and early-1970s houses (11%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. East Staffordshire Borough Council decided 311 householder applications in the latest published year and granted 95%, with 21% issued inside the eight-week target. We draw to that record rather than to a national average.

The full build-period split for Crown runs pre-1900 29% (320 homes), 1900-1918 3% (30 homes), 1919-1929 2% (20 homes), 1930-1939 5% (50 homes), 1945-1954 6% (70 homes), 1955-1964 13% (140 homes), 1965-1972 11% (120 homes), 1973-1982 10% (110 homes), 1983-1992 5% (50 homes), 1993-1999 5% (50 homes) and 2000-2008 5% (60 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.

East Staffordshire Borough Council also decides for Anglesey, Bagots & Needwood, Burton & Eton, Dove and Stramshall & Weaver, so a decision in Crown 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 East Staffordshire Borough Council's rules

Crown 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 (29% of 1,110 homes), late-1950s and early-1960s houses (13%) and late-1960s and early-1970s houses (11%), 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. East Staffordshire Borough Council judges every one of them against the adopted East Staffordshire local plan and East Staffordshire Borough 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. Crown contains Marchington, Newborough conservation areas, 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.

Crown also protects whole streets — Marchington and Newborough among them. No Article 4 direction is recorded for East Staffordshire Borough Council, but Crown's 2 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 Crown?

Plenty of Crown 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 East Staffordshire Borough 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 Marchington and Newborough, where the larger-home route and side extensions are not permitted development

Crown extension approval rates — live from council data

Below is East Staffordshire Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. East Staffordshire Borough Council granted 95% of its householder applications in the year to 31 March 2026, and Marchington 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 Crown

Across Marchington, Newborough and Marchington, 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 (29% of 1,110 homes), a side-return infill frequently pairs with it to square off the plan; on wider late-1960s and early-1970s houses (11%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.

The 1,110 homes here are 29% pre-1900, 13% 1955-1964, 11% 1965-1972, 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 East Staffordshire Borough 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 Crown home?

The right extension in Crown 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 East Staffordshire Borough 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 Marchington and Newborough and Article 4 directions can remove permitted-development rights.

Four steps to an approved Crown extension

A fixed process built around how East Staffordshire Borough 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 East Staffordshire Borough 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 East Staffordshire Borough Council issues its decision.

Frequently asked questions

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

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 Crown you will need to apply to East Staffordshire Borough 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 Marchington and Newborough.

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

Can I build a double-storey extension in Crown?

Two-storey and double-storey extensions almost always need a full householder application to East Staffordshire Borough 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 Crown address specifically.

How long does East Staffordshire Borough Council take to decide an extension application?

A householder planning application in Crown 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. East Staffordshire Borough Council is the decision-maker.

Will my extension in Crown 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 East Staffordshire Borough Council's building control or an approved inspector can sign the work off. This applies to your Crown address specifically.

How much do extension plans in Crown cost?

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