Side-return infill drawings for Dinedor Hill terraces — the glazed extension that fills the redundant side alley and opens up the kitchen, drawn to Herefordshire Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check 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.

The side return is the classic terrace fix, and Dinedor Hill has the stock for it — 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 the Victorian and Edwardian versions almost all have an L-shaped back addition with a wasted alley beside it. Fill that alley and the dark galley kitchen becomes a bright, square room the full width of the house. Herefordshire Council judges the infill against Herefordshire Council's adopted local plan and its householder design guidance, and because it runs along the party boundary, the neighbour relationship is read before the design.
That boundary is where the drawings earn their keep. We set the infill wall on or up to the line, keep the roof — usually a glazed lantern or a shallow pitch tying into the existing back-addition slope — below the neighbour's first-floor windows, and detail the rainwater and party-wall junction so the build is watertight and the Party Wall Act is satisfied. 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 section rather than leave it to the case officer.
Many of Dinedor Hill's terraces sit in conservation areas — Hoarwithy among them — where a side extension is no longer permitted development. No Article 4 direction is recorded for Herefordshire Council, but Dinedor Hill's 1 conservation area still limit permitted development on those streets. We confirm the designation before a line is drawn.
Some single-storey side returns in Dinedor Hill are permitted development, but the width and boundary make an application more likely than for a straight rear extension. You will normally need to apply to Herefordshire Council if any of these apply:
We draw the infill wall on the boundary, the glazed roof below the neighbour's windows and the party-wall junction on the page — the details Herefordshire Council's officers and your neighbour both check — 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, 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 Hoarwithy shapes what is approved here. Side returns hinge on width, roof glazing and the party boundary, so a pack that resolves those details upfront is decided faster and refused less often than a DIY submission.

Across Hoarwithy, Dinedor and Hentland, the approved side return is a single-storey infill roofed with a glazed lantern or roof light to pull daylight deep into the plan, its flank wall built on the boundary and finished to match the host brick. On the borough's victorian and earlier houses (21% of 1,800 homes), this is frequently the single biggest gain in usable ground-floor space, and where it stays within the width and height limits it can proceed under permitted development or a lawful development certificate.
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 keep the glazed roof below the neighbour's cill line, set the gutter and the party-wall flashing so water and maintenance are designed in, and — where owners want the full open-plan room — pair the infill with a rear extension as a single wraparound application. That way Herefordshire Council sees one coherent scheme rather than two overlapping ones.
We draw side-return infills on every terraced street in the borough. A few of the neighbourhoods where Dinedor Hill side returns come up most often:

Whether a side return in Dinedor Hill needs permission comes down to width, storeys and whether the street is designated. This is how the cases compare.
| Side return type | Permitted development? | What it gains | What Herefordshire Council checks |
|---|---|---|---|
| Single-storey infill, within limits | Often yes, if under half the house width | Full-width kitchen-diner | Width, 4m height, roof glazing |
| Single-storey, over half width | No — full application | Wider room, more light | Boundary treatment, neighbour amenity |
| Two-storey side return | No — full application | Room above as well as below | Bulk, overlooking, terrace rhythm |
| Wraparound (side + rear) | No — full application | L-shaped open-plan ground floor | Combined footprint, garden retained |
In conservation areas such as Hoarwithy, side extensions are not permitted development and always need a full application.
A fixed process built around how Herefordshire Council validates and decides side-return applications — most drawings are submission-ready within seven days of survey.
Send us your Dinedor Hill postcode and terrace type. We confirm your conservation and Article 4 status, whether the infill stays within the side-extension width limit, and score your odds against live Herefordshire Council decisions.
We measure the side alley, the back-addition wall, floor and eaves levels and the neighbour's window heights — the numbers the width limit, roof pitch and party-wall detailing depend on.
Chartered designers develop the infill and its glazed roof to your brief, drawn inside the permitted-development limits or to Herefordshire Council's extension guidance, with the boundary and party-wall junction detailed.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Herefordshire Council issues its decision.
Sometimes not. A single-storey side-return infill can be permitted development if it is no wider than half the original house, no higher than 4 metres, and the property is not on designated land. In Dinedor Hill you will need a full application to Herefordshire Council for anything wider or taller, for a two-storey side return, and for any side extension in a conservation area such as Hoarwithy, where those rights are removed.
It is an infill that fills the narrow open alley running alongside the rear back-addition of a Victorian or Edwardian terrace — the strip of ground that is usually too small to use. Building over it squares off the ground floor, so a cramped galley kitchen becomes a full-width room. Dinedor Hill's period terraces are ideally suited to it, which is why the side return is one of the borough's most common extensions. Herefordshire Council is the decision-maker.
Almost always. A side return is built on or up to the boundary with your neighbour, so the Party Wall etc. Act applies and you must serve notice before work starts — this is entirely separate from Herefordshire Council's planning decision. We detail the party-wall junction on the drawings and flag the notice early so a surveyor can be appointed without delaying the build. This applies to your Dinedor Hill address specifically.
Yes, and it is common — the combined L-shape is a wraparound extension. Once the side infill joins a rear projection beyond the permitted-development depth, the whole thing needs a full householder application to Herefordshire Council rather than qualifying as permitted development. We draw it as one coherent scheme so the council assesses a single footprint, which reads more clearly than two overlapping proposals. This applies to your Dinedor Hill address specifically.
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 an incomplete pack can stall at validation. Because a side return involves the boundary and roof glazing, a complete, well-detailed submission matters — we prepare it validation-complete and manage officer queries to keep the decision on track. Herefordshire Council is the decision-maker.
We price each Dinedor Hill side return individually, because alley width and roof form vary house to house, and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Herefordshire Council approves, and we confirm at the outset whether your infill is permitted development or needs an application.
