Single-storey, double-storey, rear and side extension drawings for Holmer homes — measured to Herefordshire Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
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. Holmer contains the Aylestone Hill conservation area (Aylestone Hill designated 1969), 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.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. In conservation areas such as Aylestone Hill those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Holmer is determined against an 8-week statutory target.
Aylestone Hill (conservation area designated in 1969), Holmer & Shelwick (civil parish within Holmer) and Hereford (civil parish within Holmer) — these are the Holmer pockets our drawings cover most. Heritage designations here include Aylestone Hill. Herefordshire Council weighs each proposal against Herefordshire Council's development plan and the design policies it applies to householder applications, where the 2,320 homes here are 13% 1955-1964, 10% 1983-1992, 9% pre-1900, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow gabled roofs typical of that period's building and trussed-rafter roofs typical of 1980s building, over late-1950s and early-1960s houses (13% of 2,320 homes), 1980s estate houses (10%) and Victorian and earlier houses (9%).
Before anything is drawn we check your address against the designations that apply in Holmer: Aylestone Hill (conservation area designated in 1969). 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, Holmer takes in Holmer & Shelwick and Hereford. No Article 4 direction is recorded for Herefordshire Council, but Holmer's 1 conservation area still limit permitted development on those streets.
On stock, Holmer is late-1950s and early-1960s houses (13% of 2,320 homes), 1980s estate houses (10%) and Victorian and earlier houses (9%) — which is why shallow gabled roofs typical of that period's 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. That decision record, not a national figure, is what we design to.
The full build-period split for Holmer runs pre-1900 9% (200 homes), 1900-1918 1% (20 homes), 1919-1929 1% (30 homes), 1930-1939 4% (100 homes), 1945-1954 3% (80 homes), 1955-1964 13% (300 homes), 1965-1972 3% (70 homes), 1973-1982 3% (60 homes), 1983-1992 10% (240 homes), 1993-1999 6% (150 homes) and 2000-2008 2% (50 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 Holmer 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.

Holmer homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from late-1950s and early-1960s houses (13% of 2,320 homes), 1980s estate houses (10%) and Victorian and earlier houses (9%), 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. Herefordshire Council judges every one of them against Herefordshire Council's development plan and the design policies it applies to householder applications, 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. Holmer contains the Aylestone Hill conservation area (Aylestone Hill designated 1969), 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.
Holmer also protects whole streets — Aylestone Hill among them. No Article 4 direction is recorded for Herefordshire Council, but Holmer's 1 conservation area 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.
Plenty of Holmer 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 Herefordshire Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Herefordshire Council's officers weigh first — and submit a validation-complete pack, whether that is a lawful development certificate, a prior-approval notification 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 Aylestone Hill 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.

Across Aylestone Hill, Holmer & Shelwick and Hereford, 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 late-1950s and early-1960s houses (13% of 2,320 homes), a side-return infill frequently pairs with it to square off the plan; on wider victorian and earlier houses (9%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 2,320 homes here are 13% 1955-1964, 10% 1983-1992, 9% pre-1900, 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 Herefordshire 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.
We draw extensions on every street in the borough. A few of the neighbourhoods where Holmer projects come up most often:
Extension drawings for Aylestone Hill's conservation area designated in 1969 — footprint-checked, daylight-tested and drawn to Herefordshire Council's guidance.
Extension drawings for Holmer & Shelwick's civil parish within Holmer — footprint-checked, daylight-tested and drawn to Herefordshire Council's guidance.
Extension drawings for Hereford's civil parish within Holmer — footprint-checked, daylight-tested and drawn to Herefordshire Council's guidance.
The right extension in Holmer 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 type | Permitted development? | What it adds | What Herefordshire Council checks |
|---|---|---|---|
| Single-storey rear | Often, within 3m/4m depth (6m/8m via prior approval) | Bigger kitchen-diner across the back | Depth, height, neighbour daylight (45°) |
| Side-return infill | Sometimes, if within width and height limits | Squares off an L-shaped ground floor | Width vs the original house, glazing to boundary |
| Two-storey rear/side | No — full application | Extra bedroom or bathroom above | Bulk, overlooking, 7m rear-boundary gap |
| Wraparound (rear + side) | No — full application | Whole-width open-plan ground floor | Combined footprint and garden retained |
Route depends on your street — conservation areas such as Aylestone Hill and Article 4 directions can remove permitted-development rights.
A fixed process built around how Herefordshire Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Holmer postcode and house type. We confirm your conservation and Article 4 status, how much permitted-development depth you have left, and score your odds against live Herefordshire Council decisions.
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.
Chartered designers develop the single-storey, two-storey or side extension to your brief, drawn inside the permitted-development limits or to Herefordshire Council's extension design guidance.
We submit the certificate, prior-approval notice or application, manage validation and case-officer queries, and revise the drawings free until Herefordshire Council issues its decision.
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 Holmer you will need to apply to Herefordshire 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 Aylestone Hill.
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 Herefordshire Council and a neighbour-consultation period, and it does not apply on designated land such as Holmer's conservation areas. We confirm which route your property qualifies for before drawing.
Two-storey and double-storey extensions almost always need a full householder application to Herefordshire 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 Holmer address specifically.
A householder planning application in Holmer 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. Herefordshire Council is the decision-maker.
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 Herefordshire Council's building control or an approved inspector can sign the work off. This applies to your Holmer address specifically.
Every house and brief is different, so we price each Holmer extension individually and send a fixed, no-obligation quote back within one working day.
