Two-storey extension drawings for Herefordshire homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Herefordshire Council's design guidance, 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.

Adding at first floor changes the question the case officer asks. A single-storey extension is judged mostly on daylight and garden loss; a two-storey extension is judged on overlooking, bulk against the neighbouring roofline, and whether it reads as part of the house or bolted onto it. Herefordshire is largely Victorian and earlier houses (30% of 38,030 homes), 1970s and early-1980s houses (8%) and 1980s estate houses (6%), and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow trussed roofs typical of 1970s building set what a matching roof actually means here.
The permitted-development route exists but is narrow: 3 metres of rear projection, a 7-metre stand-off from the rear boundary, eaves and ridge no higher than the original, and side-facing upper windows obscure-glazed and non-opening below 1.7 metres above floor level. Most two-storey schemes fail one of those, usually the 7-metre boundary rule on a shorter garden, and go in as a full application instead. We establish which route applies before designing, because it changes the drawing set.
Herefordshire contains Almeley, Aylestone Hill, Eastnor conservation areas (Almeley designated 1987), so materials, fenestration and roof form are assessed against the appraisal. No Article 4 direction is recorded for Herefordshire Council, but the district's 8 conservation areas still limit permitted development on those streets.
Some two-storey rear extensions are permitted development. You will need a full application to Herefordshire Council if any of these apply:
We set the projection and boundary distance on the site plan, prove the roof-pitch match on the elevations, and specify obscure glazing on the side windows — the three things Herefordshire Council checks first — then submit a validation-complete pack.
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. Two-storey schemes attract more neighbour comment than any other householder work, so the overlooking and daylight case has to be made on the drawings.

Across Almeley, Aylestone Hill and Eastnor, the schemes that succeed set the first floor back from the ground floor, keep the ridge below the original, and treat the flank wall as blank or obscure-glazed. On victorian and earlier houses (30% of 38,030 homes), matching the eaves line matters more than matching the brick: an extension that carries the existing eaves through reads as original even in a different material.
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. We draw the 45-degree daylight test from the neighbour's nearest habitable window, show the window positions in section, and set out the steel and foundation implications early — a two-storey extension changes the load path, so the structural design and the planning design have to be developed together rather than in sequence.
We draw two-storey extensions across Herefordshire. A few of the areas where they come up most often:
Two storey extension drawings for Almeley — conservation area designated in 1987 — dimensioned against the 3m and 7m limits and drawn to Herefordshire Council's guidance.
Two storey extension drawings for Aylestone Hill — conservation area designated in 1969 — dimensioned against the 3m and 7m limits and drawn to Herefordshire Council's guidance.
Two storey extension drawings for Eastnor — conservation area designated in 1991 — dimensioned against the 3m and 7m limits and drawn to Herefordshire Council's guidance.
Two storey extension drawings for Fownhope — conservation area designated in 1976 — dimensioned against the 3m and 7m limits and drawn to Herefordshire Council's guidance.
Two storey extension drawings for Hafod Road — conservation area designated in 1992 — dimensioned against the 3m and 7m limits and drawn to Herefordshire Council's guidance.
Two storey extension drawings for Hampton Bishop — conservation area designated in 1987 — dimensioned against the 3m and 7m limits and drawn to Herefordshire Council's guidance.
The first-floor limits are tighter than the ground-floor ones. This is how the common cases compare.
| Scheme | Permitted development? | Deciding limit | What Herefordshire Council checks |
|---|---|---|---|
| Two-storey rear, 3m projection, 7m+ to boundary | Often yes | 3m projection / 7m boundary | Roof match, side-window glazing |
| Two-storey rear, under 7m to boundary | No — full application | Rear-boundary distance | Overlooking, daylight, garden loss |
| Two-storey side extension | No — full application | Side elevation | Gap to boundary, street rhythm |
| Two-storey wraparound | No — full application | Combined footprint | Bulk, massing, neighbour amenity |
| Any two-storey on designated land | No — full application | Designation | Character and appearance |

A fixed process built around how Herefordshire Council validates and decides two-storey applications.
Send us your Herefordshire postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Herefordshire Council decisions.
We measure the original rear wall, eaves and ridge heights, garden depth and every neighbouring window that faces the site — the inputs the daylight and overlooking case is built from.
Chartered designers develop the two-storey addition to your brief with the roof and eaves resolved, and we coordinate the load path so the structural scheme and the planning scheme are the same building.
We submit the application, manage validation and case-officer queries, and revise the drawings free until Herefordshire Council issues its decision.
Often, but not always. A two-storey rear extension can be permitted development if it projects no more than 3 metres, sits at least 7 metres from the rear boundary, does not exceed the existing eaves and ridge, and has obscure-glazed non-opening side windows below 1.7 metres. In Herefordshire, the 7-metre rule is what most commonly forces a full application to Herefordshire Council.
No part of a permitted-development two-storey rear extension may come within 7 metres of the boundary opposite the rear wall of the house. It exists to protect the neighbour behind you from being overlooked at first floor. On shorter Herefordshire gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Herefordshire Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to Herefordshire Council. They are assessed on the gap to the boundary, whether the street's rhythm of spaces between houses survives, and whether the extension is subordinate to the original. Setting the first floor back from the front building line and down from the ridge is what usually makes the difference.
Overlooking is the most common objection, and it is answerable on the drawings. We position habitable-room windows away from neighbouring gardens, obscure-glaze and fix shut anything on the flank below 1.7 metres, and show the sight lines in section. Where the geometry is tight, a rooflight or a high-level window gives the same daylight without the mutual overlooking that draws objections. This applies to your Herefordshire address specifically. Herefordshire Council is the decision-maker.
Almost certainly. Excavating within 3 metres of a neighbouring structure and building on or up to the boundary both trigger the Party Wall etc. Act 1996, and a two-storey extension usually does both. It is entirely separate from Herefordshire Council's planning decision, so we flag the notice period early and detail the junction on the drawings.
Yes. Adding a floor changes the load path from roof to foundation, so beams, padstones and foundation depths all need designing and calculating for building control. Planning and building regulations are separate consents, and the structural set is what building control assesses — we prepare both so the approved scheme is the buildable one. This applies to your Herefordshire address specifically. Herefordshire Council is the decision-maker.
