Dormer, hip-to-gable and mansard loft conversion drawings for Dinedor Hill homes — prepared to Herefordshire Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
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. Dinedor Hill contains the Hoarwithy conservation area (Hoarwithy designated 1976), 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 Hoarwithy those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Dinedor Hill is determined against an 8-week statutory target.
Hoarwithy (conservation area designated in 1976), Dinedor (civil parish within Dinedor Hill), Hentland (civil parish within Dinedor Hill), Holme Lacy (civil parish within Dinedor Hill), Ballingham (civil parish within Dinedor Hill), Bolstone (civil parish within Dinedor Hill) and Little Dewchurch (civil parish within Dinedor Hill) — these are the Dinedor Hill pockets our drawings cover most. Heritage designations here include Hoarwithy. Herefordshire Council weighs each proposal against Herefordshire Council's adopted local plan and its householder design guidance, where the 1,800 homes here are 21% pre-1900, 16% 1983-1992, 16% 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 (21% of 1,800 homes), 1980s estate houses (16%) and 2000s houses and apartments (16%).
What is permitted in Dinedor Hill turns on designation first, so that is where we start: 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, Dinedor Hill takes in Dinedor, Hentland, Holme Lacy, Ballingham, Bolstone and Little Dewchurch. No Article 4 direction is recorded for Herefordshire Council, but Dinedor Hill's 1 conservation area still limit permitted development on those streets.
On stock, Dinedor Hill is Victorian and earlier houses (21% of 1,800 homes), 1980s estate houses (16%) and 2000s houses and apartments (16%) — 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. 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 Dinedor Hill runs pre-1900 21% (370 homes), 1900-1918 1% (20 homes), 1919-1929 1% (20 homes), 1930-1939 2% (30 homes), 1945-1954 3% (60 homes), 1955-1964 13% (230 homes), 1965-1972 3% (50 homes), 1973-1982 7% (120 homes), 1983-1992 16% (290 homes), 1993-1999 14% (260 homes) and 2000-2008 16% (280 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, Eign Hill, Hagley and Holmer, so a decision in Dinedor Hill 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.

Dinedor Hill's roofs set the brief. The borough is built largely from Victorian and earlier houses (21% of 1,800 homes), 1980s estate houses (16%) and 2000s houses and apartments (16%), and its lofts sit under steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 1980s building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Herefordshire Council assesses loft proposals against Herefordshire Council's adopted local plan and its householder design guidance, and its case officers read each roof against the pair next door and the wider street before they read the plans.
That makes drawing quality decisive. We measure ridge and eaves heights, roof pitch and the existing stair, calculate the added volume against the permitted-development limits exactly, and show the workings on the drawings so Herefordshire Council can verify them. Dinedor Hill contains the Hoarwithy conservation area (Hoarwithy designated 1976), so materials, fenestration and roof form are assessed against the appraisal, so we resolve it on the page rather than leave it for the case officer to raise.
Dinedor Hill also carries protected streets — Hoarwithy among them. No Article 4 direction is recorded for Herefordshire Council, but Dinedor Hill's 1 conservation area still limit permitted development on those streets. We check your address against those designations before a line is drawn.
Many Dinedor Hill loft conversions proceed without planning permission — a rear dormer within the permitted-development volume limits (40 cubic metres on a terrace, 50 on a semi or detached house) is usually lawful. You will normally need a full application to Herefordshire Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Herefordshire Council's officers check first — and submit a validation-complete pack, whether that is a lawful development certificate or a full householder application.
Below is Herefordshire Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Herefordshire Council granted 95% of its householder applications in the year to 31 March 2026, and Hoarwithy shapes what is approved here. Professionally prepared loft drawings anticipate those pressure points before submission, which is why complete, policy-literate packs are decided faster and refused less often than DIY applications.

Across Hoarwithy, Dinedor and Hentland, the recurring loft is the rear dormer — a box across the back roof slope that turns a cramped attic into a full-height double bedroom and en-suite. On steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, that is usually the most efficient use of the roof; where the stock is trussed-rafter roofs typical of 1980s building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 1,800 homes here are 21% pre-1900, 16% 1983-1992, 16% 2000-2008, which is what sets the realistic roof and rear-projection options. We draw the dormer inside the volume allowance, keep the flat-roof build-up below the ridge, and set the face back from the eaves as the rules require — so the pack answers Herefordshire Council's questions before they are asked. Where permitted-development rights are exhausted or removed, we prepare a householder application composed to the borough's roof-alteration guidance instead.
We draw loft conversions on every street in the borough. A few of the neighbourhoods where Dinedor Hill roofs come up most often:

The right loft in Dinedor Hill depends on your roof. This is how the main types compare on planning route and the space they add.
| Loft type | Permitted development? | Space & headroom | What Herefordshire Council checks |
|---|---|---|---|
| Rear dormer | Usually yes, within volume limits | Full-height double room at the back | Volume, set-back from eaves, ridge height |
| Hip-to-gable | No — full application | Extends the whole side of the roof | Roof bulk and the symmetry of the pair |
| Mansard | No — full application | Maximum floor area across the roof | Street character, especially in conservation areas |
| Rooflights only | Usually yes (Class C) | Light and headroom, no extra footprint | Whether rooflights sit within the existing slope |
Route depends on your street — conservation areas such as Hoarwithy and Article 4 directions can remove permitted-development rights.
A fixed process built around how Herefordshire Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Dinedor Hill postcode and roof type. We confirm your conservation and Article 4 status, how much permitted-development volume you have left, and score your odds against live Herefordshire Council decisions.
We measure ridge and eaves heights, roof pitch, joist levels and the existing stair — the numbers the volume calculation and head heights depend on.
Chartered designers develop the dormer, hip-to-gable or mansard to your brief, drawn inside the Class B limits or to Herefordshire Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Herefordshire Council issues its decision.
Often not. A rear dormer within 40 cubic metres on a terrace, or 50 on a semi-detached or detached house, set back from the eaves and no higher than the ridge, is usually permitted development. In Dinedor Hill the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Hoarwithy or on streets with an Article 4 direction. Herefordshire Council is the decision-maker.
Generally no. In conservation areas including Hoarwithy, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Herefordshire Council. No Article 4 direction is recorded for Herefordshire Council, but Dinedor Hill's 1 conservation area still limit permitted development on those streets. We check your exact address before drawing.
On steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, common across Dinedor Hill, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is trussed-rafter roofs typical of 1980s building, a hip-to-gable followed by a rear dormer gains far more usable space but needs planning permission. Our survey confirms which your roof supports before we draw. Herefordshire Council is the decision-maker.
A householder planning application in Dinedor Hill runs to a statutory eight-week target, and a lawful development certificate to eight weeks as well, though validation can add time if the pack is incomplete. We submit validation-complete drawings and manage case-officer queries to keep the decision on track. Herefordshire Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Herefordshire Council is council-stamped proof of that — worth having, because every buyer's solicitor will ask for it when you sell. We prepare and submit the certificate application with the same drawing pack. This applies to your Dinedor Hill address specifically.
Every roof is different, so we quote each Dinedor Hill project individually — a fixed, no-obligation price back within one working day.
