Annexe and granny-flat drawings for Herefordshire homes — designed to stay ancillary to the main house rather than become a separate dwelling, drawn to Herefordshire Council's policies, delivered in days and revised free until your decision.
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. Herefordshire contains Almeley, Aylestone Hill, Eastnor 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.
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 Almeley, Aylestone Hill and Eastnor those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Herefordshire is determined against an 8-week statutory target.
Almeley (conservation area designated in 1987), Aylestone Hill (conservation area designated in 1969), Eastnor (conservation area designated in 1991), Fownhope (conservation area designated in 1976), Hafod Road (conservation area designated in 1992), Hampton Bishop (conservation area designated in 1987), Hereford, Hampton Park (conservation area designated in 1969), Hoarwithy (conservation area designated in 1976), Arrow (ward of Herefordshire), Backbury (ward of Herefordshire), Birch (ward of Herefordshire), Bircher (ward of Herefordshire), Castle (ward of Herefordshire), Dinedor Hill (ward of Herefordshire), Eign Hill (ward of Herefordshire) and Hagley (ward of Herefordshire) — these are the Herefordshire pockets our drawings cover most. Heritage designations here include Almeley, Aylestone Hill, Eastnor, Fownhope, Hafod Road, Hampton Bishop, Hereford, Hampton Park and Hoarwithy. Herefordshire Council weighs each proposal against the adopted Herefordshire local plan and Herefordshire Council's design guidance for householder work, where the 38,030 homes here are 30% pre-1900, 8% 1973-1982, 6% 1983-1992, 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 trussed roofs typical of 1970s building, over Victorian and earlier houses (30% of 38,030 homes), 1970s and early-1980s houses (8%) and 1980s estate houses (6%).
Herefordshire's designated heritage is specific, and it is the first thing we check against your address: Almeley (conservation area designated in 1987), Aylestone Hill (conservation area designated in 1969), Eastnor (conservation area designated in 1991), Fownhope (conservation area designated in 1976), Hafod Road (conservation area designated in 1992), Hampton Bishop (conservation area designated in 1987), Hereford, Hampton Park (conservation area designated in 1969) and Hoarwithy (conservation area designated in 1976). 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, Herefordshire takes in Arrow, Backbury, Birch, Bircher, Castle, Dinedor Hill, Eign Hill and Hagley. No Article 4 direction is recorded for Herefordshire Council, but the district's 8 conservation areas still limit permitted development on those streets.
On stock, Herefordshire is Victorian and earlier houses (30% of 38,030 homes), 1970s and early-1980s houses (8%) and 1980s estate houses (6%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow trussed roofs typical of 1970s 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. Those are the numbers our drawings are prepared against.
The full build-period split for Herefordshire runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 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, Castle, Dinedor Hill, Eign Hill and Hagley, so a decision in Herefordshire 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.

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.
Herefordshire is largely Victorian and earlier houses (30% of 38,030 homes), 1970s and early-1980s houses (8%) and 1980s estate 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 Herefordshire's conservation areas — including Almeley and Aylestone Hill — 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 the district's 8 conservation areas still limit permitted development on those streets.
An annexe almost always needs an application to Herefordshire Council. Expect one where any of these apply:
We plan the annexe so its relationship to the main house is visible on the page — shared garden, connected access, a layout that reads as one household — and set out the case Herefordshire Council has to test, rather than leaving the officer to assume the worst.
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 524 householder decisions in the year to 31 March 2026, 46% of them inside eight weeks. Annexe applications are decided on use as much as design, so the supporting case matters as much as the elevations.

Across Almeley, Aylestone Hill and Eastnor, 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 (30% of 38,030 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.
Herefordshire contains Almeley, Aylestone Hill, Eastnor 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.
We draw annexes across Herefordshire. A few of the areas where multigenerational schemes come up most often:

Three similar buildings, three different consents. This is what separates them.
| What you build | Planning status | Key test | What Herefordshire Council checks |
|---|---|---|---|
| Garden room, no sleeping space | Often Class E permitted development | Incidental to the house | Height, footprint, boundary position |
| Annexe used by the household | Full application, usually with a tie condition | Ancillary use | Shared garden and access, layout |
| Self-contained unit, own access | New dwelling — full application | Separate planning unit | Policy on new homes, amenity, parking |
| Converted garage or ground floor | Often permitted, use still assessed | Whether use changes | Independence of the accommodation |
| Annexe on designated land | Full application | Designation | Character 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.
A fixed process built around how Herefordshire Council tests the use question as well as the design.
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 Herefordshire.
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.
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.
We submit the application with a supporting statement on use, manage validation and case-officer queries, and revise free until Herefordshire Council decides.
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 Herefordshire we prepare a full application to Herefordshire Council and make the ancillary case explicitly rather than hoping it is not asked.
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.
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 Herefordshire, particularly near designated areas such as Almeley and Aylestone Hill. Herefordshire Council is the decision-maker.
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 Herefordshire address specifically. Herefordshire Council is the decision-maker.
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 Herefordshire address specifically. Herefordshire Council is the decision-maker.
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 Herefordshire address specifically. Herefordshire Council is the decision-maker.
