Castle planning decisions and design rules

Herefordshire Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. Castle contains Almeley, Staunton on Wye conservation areas (Almeley designated 1987), 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.

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 Almeley and Staunton on Wye those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Castle is determined against an 8-week statutory target.

Almeley (conservation area designated in 1987), Staunton on Wye (conservation area designated in 1995), Eardisley (civil parish within Castle), Almeley (civil parish within Castle), Brilley (civil parish within Castle), Brobury with Monnington on Wye (civil parish within Castle), Kinnersley (civil parish within Castle) and Letton (civil parish within Castle) — these are the Castle pockets our drawings cover most. Heritage designations here include Almeley and Staunton on Wye. Herefordshire Council weighs each proposal against Herefordshire Council's adopted local plan and its householder design guidance, where the 1,550 homes here are 47% pre-1900, 7% 2000-2008, 6% 1973-1982, 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 2000s building, over Victorian and earlier houses (47% of 1,550 homes), 2000s houses and apartments (7%) and 1970s and early-1980s houses (6%).

Why a Castle scheme is judged on Castle terms

What is permitted in Castle turns on designation first, so that is where we start: Almeley (conservation area designated in 1987) and Staunton on Wye (conservation area designated in 1995). Inside those boundaries permitted development is curtailed and Herefordshire 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, Castle takes in Eardisley, Almeley, Brilley, Brobury with Monnington on Wye, Kinnersley and Letton. No Article 4 direction is recorded for Herefordshire Council, but Castle's 2 conservation areas still limit permitted development on those streets.

On stock, Castle is Victorian and earlier houses (47% of 1,550 homes), 2000s houses and apartments (7%) and 1970s and early-1980s houses (6%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 2000s building govern what a loft or rear projection can realistically be. Herefordshire Council decided 524 householder applications in the latest published year and granted 95%, with 46% issued inside the eight-week target. We draw to that record rather than to a national average.

The full build-period split for Castle runs pre-1900 47% (730 homes), 1900-1918 1% (20 homes), 1919-1929 2% (30 homes), 1930-1939 3% (40 homes), 1945-1954 4% (60 homes), 1955-1964 4% (60 homes), 1965-1972 6% (90 homes), 1973-1982 6% (100 homes), 1983-1992 3% (40 homes), 1993-1999 6% (100 homes) and 2000-2008 7% (110 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.

Herefordshire Council also decides for Arrow, Backbury, Birch, Bircher, Dinedor Hill, Eign Hill, Hagley and Holmer, so a decision in Castle 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.

Ancillary or separate dwelling — the Castle test

Councils do not decide annexes on square metres. They decide whether, once built, the accommodation forms part of one planning unit with the main house or a second one beside it. Herefordshire Council looks at whether the garden is shared or divided, whether the annexe has its own street access and address, whether the occupier could live there entirely independently, and whether the two households would function as one. That is the whole case, and it is made or lost on the layout.

Castle is largely Victorian and earlier houses (47% of 1,550 homes), 2000s houses and apartments (7%) and 1970s and early-1980s houses (6%), which shapes the realistic options: converting part of the existing house, extending it, or building a detached unit in the garden. A detached annexe can sometimes sit under Class E as an outbuilding incidental to the enjoyment of the dwellinghouse — but sleeping accommodation is generally not "incidental", so a garden annexe with a bedroom usually needs its own permission rather than relying on outbuilding rights.

In Castle's conservation areas — including Almeley and Staunton on Wye — a garden building is also judged on its effect on the character of the area, which limits height and footprint before the use question is reached. No Article 4 direction is recorded for Herefordshire Council, but Castle's 2 conservation areas still limit permitted development on those streets.

Annexe accommodation designed for a Castle property

When does an annexe need planning permission in Castle?

An annexe almost always needs an application to Herefordshire Council. Expect one where any of these apply:

  • The accommodation includes sleeping space, so it is not incidental under Class E
  • There is a separate entrance from the street rather than through the shared garden
  • The garden would be divided so each part serves one unit
  • The annexe has its own kitchen, utilities and postal address
  • It would be let, sold or occupied by someone unconnected to the main household
  • The property is on designated land such as Almeley and Staunton on Wye, where outbuilding rights are curtailed

Castle annexe decisions — live from council data

Below is Herefordshire Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Herefordshire Council granted 95% of its householder applications in the year to 31 March 2026, and Almeley shapes what is approved here. Annexe applications are decided on use as much as design, so the supporting case matters as much as the elevations.

What annexes get approved across Castle

Across Almeley, Staunton on Wye and Eardisley, the annexes that succeed keep one shared garden, take access past the main house rather than from the street, and are modest against the host building — single storey where the plot is overlooked, and set back from boundaries. On victorian and earlier houses (47% of 1,550 homes), converting an integral garage or a rear ground floor is often approved more readily than a detached garden unit, because the ancillary relationship is self-evident.

Castle contains Almeley, Staunton on Wye conservation areas (Almeley designated 1987), so materials, fenestration and roof form are assessed against the appraisal. Where Herefordshire Council grants permission, it commonly attaches a condition tying occupation of the annexe to the main dwelling. That condition is not a problem to be avoided — it is usually the mechanism that makes approval possible, and we draft the application on that basis rather than pretending the annexe is something it is not.

Annexe, outbuilding or new dwelling in Castle?

Three similar buildings, three different consents. This is what separates them.

What you buildPlanning statusKey testWhat Herefordshire Council checks
Garden room, no sleeping spaceOften Class E permitted developmentIncidental to the houseHeight, footprint, boundary position
Annexe used by the householdFull application, usually with a tie conditionAncillary useShared garden and access, layout
Self-contained unit, own accessNew dwelling — full applicationSeparate planning unitPolicy on new homes, amenity, parking
Converted garage or ground floorOften permitted, use still assessedWhether use changesIndependence of the accommodation
Annexe on designated landFull applicationDesignationCharacter and appearance

The ancillary/separate-dwelling distinction comes from section 55 of the Town and Country Planning Act 1990; outbuilding limits from the GPDO 2015, Schedule 2, Part 1, Class E.

Four steps to an approved Castle annexe

A fixed process built around how Herefordshire Council tests the use question as well as the design.

  1. 1

    Free approval check

    Tell us who the annexe is for and where it would sit on the plot. We confirm designation status and tell you honestly whether the scheme reads as ancillary or as a separate dwelling in Castle.

  2. 2

    Measured survey

    We measure the plot, the existing house and the access route, so the shared-garden and shared-access case can be drawn rather than asserted.

  3. 3

    Annexe design & drawings

    Chartered designers develop the annexe to your brief, with the layout, access and garden relationship arranged to support the ancillary case under Herefordshire Council's policies.

  4. 4

    Submission & follow-through

    We submit the application with a supporting statement on use, manage validation and case-officer queries, and revise free until Herefordshire Council decides.

Frequently asked questions

Do I need planning permission for an annexe in Castle?

Almost always. Sleeping accommodation is generally not "incidental" to the enjoyment of a house, so it falls outside the outbuilding permitted-development right, and any annexe that could function independently raises a change-of-use question under section 55. In Castle we prepare a full application to Herefordshire Council and make the ancillary case explicitly rather than hoping it is not asked.

What makes an annexe ancillary rather than a separate dwelling in Castle?

A shared garden rather than a divided one, access through the main property rather than a separate street entrance, occupation by a member of the same household, and a physical and functional relationship with the main house. Herefordshire Council weighs those together — no single feature decides it, but a separate front door and a fenced-off garden together usually settle it against you. This applies to your Castle address specifically.

Can I build a granny flat in the garden in Castle?

Yes, subject to permission. A detached garden annexe is assessed on its scale against the plot, its effect on neighbours and the character of the area, and then on the use question. Keeping it single storey, set in from boundaries and served off the shared garden gives it the best prospect in Castle, particularly near designated areas such as Almeley and Staunton on Wye. Herefordshire Council is the decision-maker.

Will Herefordshire Council attach conditions to an annexe permission?

Commonly, yes — a condition tying occupation of the annexe to the main dwelling, so it cannot be sold or let separately. That is normally what makes approval possible, because it removes the concern that a new independent home is being created without going through housing policy. The condition runs with the land, so it matters at resale, and we explain the implications before you commit. This applies to your Castle address specifically. Herefordshire Council is the decision-maker.

Does an annexe need building regulations approval in Castle?

Yes. A new annexe is new habitable accommodation, so structure, fire escape, insulation and ventilation all apply, and a detached annexe close to a boundary raises fire-spread requirements as well. Planning and building control are separate consents with separate submissions — we prepare both so the approved design is the one that can actually be built. This applies to your Castle address specifically. Herefordshire Council is the decision-maker.

How long does an annexe application take in Castle?

A householder application runs to an eight-week statutory target; where the council treats the annexe as creating a new unit it becomes a minor application with a thirteen-week target instead. Which route applies depends on how the use is characterised, which is precisely why the ancillary case is worth making properly at the outset. This applies to your Castle address specifically. Herefordshire Council is the decision-maker.

How much do annexe plans in Castle cost?

We quote each Castle annexe individually, because plot, access and whether you are converting or building new all change the work, and send a fixed, no-obligation quote within one working day. It covers the full drawing pack and supporting statement, with free revisions until Herefordshire Council approves. Call 020 7864 7245 to start.
