Dormer, hip-to-gable and mansard loft conversion drawings for Horsehay & Lightmoor homes — prepared to Telford & Wrekin Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Telford & Wrekin Council granted 91% of the householder planning decisions it made in its latest published year — 4 points above the 87% England-wide householder average. Horsehay & Lightmoor contains the Horsehay and Spring Village conservation area, so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant postwar (1945–1970) 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 Horsehay and Spring Village those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Horsehay & Lightmoor is determined against an 8-week statutory target.
Horsehay and Spring Village (designated conservation area), Great Dawley (civil parish within Horsehay & Lightmoor), The Gorge (civil parish within Horsehay & Lightmoor) and Dawley Hamlets (civil parish within Horsehay & Lightmoor) — these are the Horsehay & Lightmoor pockets our drawings cover most. Heritage designations here include Horsehay and Spring Village. Telford & Wrekin Council weighs each proposal against Telford & Wrekin Council's adopted local plan and its householder design guidance, where the 2,830 homes here are 10% 1955-1964, 8% 1993-1999, 7% 1945-1954, 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 1990s building, over late-1950s and early-1960s houses (10% of 2,830 homes), 1990s estate houses (8%) and early postwar houses (7%).
What is permitted in Horsehay & Lightmoor turns on designation first, so that is where we start: Horsehay and Spring Village (designated conservation area). Inside those boundaries permitted development is curtailed and Telford & Wrekin 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, Horsehay & Lightmoor takes in Great Dawley, The Gorge and Dawley Hamlets. No Article 4 direction is recorded for Telford & Wrekin Council, but Horsehay & Lightmoor's 1 conservation area still limit permitted development on those streets.
On stock, Horsehay & Lightmoor is late-1950s and early-1960s houses (10% of 2,830 homes), 1990s estate houses (8%) and early postwar houses (7%) — which is why shallow gabled roofs typical of that period's building and trussed-rafter roofs typical of 1990s building govern what a loft or rear projection can realistically be. Telford & Wrekin Council decided 277 householder applications in the latest published year and granted 91%, with 96% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Horsehay & Lightmoor runs pre-1900 6% (160 homes), 1900-1918 0% (10 homes), 1919-1929 0% (10 homes), 1945-1954 7% (190 homes), 1955-1964 10% (290 homes), 1965-1972 1% (40 homes), 1973-1982 4% (110 homes), 1983-1992 2% (70 homes), 1993-1999 8% (240 homes) and 2000-2008 5% (130 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.
Telford & Wrekin Council also decides for Edgmond, Ercall Magna, Ironbridge Gorge and Wrockwardine, so a decision in Horsehay & Lightmoor 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.

Horsehay & Lightmoor's roofs set the brief. The borough is built largely from late-1950s and early-1960s houses (10% of 2,830 homes), 1990s estate houses (8%) and early postwar houses (7%), and its lofts sit under shallow gabled roofs typical of that period's building and trussed-rafter roofs typical of 1990s building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Telford & Wrekin Council assesses loft proposals against Telford & Wrekin 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 Telford & Wrekin Council can verify them. Horsehay & Lightmoor contains the Horsehay and Spring Village conservation area, 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.
Horsehay & Lightmoor also carries protected streets — Horsehay and Spring Village among them. No Article 4 direction is recorded for Telford & Wrekin Council, but Horsehay & Lightmoor's 1 conservation area still limit permitted development on those streets. We check your address against those designations before a line is drawn.
Many Horsehay & Lightmoor 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 Telford & Wrekin Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Telford & Wrekin 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 Telford & Wrekin Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Telford & Wrekin Council granted 91% of its householder applications in the year to 31 March 2026, and Horsehay and Spring Village 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 Horsehay and Spring Village, Great Dawley and The Gorge, 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 shallow gabled roofs typical of that period's building, that is usually the most efficient use of the roof; where the stock is trussed-rafter roofs typical of 1990s building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 2,830 homes here are 10% 1955-1964, 8% 1993-1999, 7% 1945-1954, 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 Telford & Wrekin 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.

The right loft in Horsehay & Lightmoor 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 Telford & Wrekin 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 Horsehay and Spring Village and Article 4 directions can remove permitted-development rights.
A fixed process built around how Telford & Wrekin Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Horsehay & Lightmoor 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 Telford & Wrekin 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 Telford & Wrekin Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Telford & Wrekin 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 Horsehay & Lightmoor the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Horsehay and Spring Village or on streets with an Article 4 direction. Telford & Wrekin Council is the decision-maker.
Generally no. In conservation areas including Horsehay and Spring Village, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Telford & Wrekin Council. No Article 4 direction is recorded for Telford & Wrekin Council, but Horsehay & Lightmoor's 1 conservation area still limit permitted development on those streets. We check your exact address before drawing.
On shallow gabled roofs typical of that period's building, common across Horsehay & Lightmoor, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is trussed-rafter roofs typical of 1990s 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. Telford & Wrekin Council is the decision-maker.
A householder planning application in Horsehay & Lightmoor 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. Telford & Wrekin Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Telford & Wrekin 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 Horsehay & Lightmoor address specifically.
