Dormer, hip-to-gable and mansard loft conversion drawings for Allesley homes — prepared to Coventry City Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Coventry City Council granted 86% of the householder planning decisions it made in its latest published year — 1 point below the 87% England-wide householder average. The Coundon Wedge green belt around the village strictly limits new building and larger replacement dwellings on the rural edge, which is where a policy-literate drawing pack earns its keep. Its dominant interwar (1918–1939) 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 Allesley Village and Brownshill Green those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Allesley is determined against an 8-week statutory target.
Allesley Village (a conservation area of cottages and a medieval church core designated in 1968), Brownshill Green (a small conservation area of rural-edge cottages to the north), Allesley Park (post-war and 1960s suburban housing south of the village), Allesley Green (later detached and semi-detached estates toward the A45), Coundon Wedge (green-belt farmland separating the village from the built-up city) and Eastern Green fringe (interwar and post-war semis on the western edge) — these are the Allesley pockets our drawings cover most. Heritage designations here include Allesley Village and Brownshill Green. Coventry City Council weighs each proposal against the Coventry Local Plan (2017), where the Allesley Village conservation area protects its cottage scale, materials and church setting in fine grain. On roofs the borough is steep tiled and part-thatched roofs on the village cottages and hipped roofs on the interwar and post-war semis and detached homes, over historic village cottages and farmhouses, 1930s interwar semi-detached houses and post-war and later suburban detached homes.
Allesley's roofs set the brief. The borough is built largely from historic village cottages and farmhouses, 1930s interwar semi-detached houses and post-war and later suburban detached homes, and its lofts sit under steep tiled and part-thatched roofs on the village cottages and hipped roofs on the interwar and post-war semis and detached homes — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Coventry City Council assesses loft proposals against the Coventry Local Plan (2017), 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 Coventry City Council can verify them. The Coundon Wedge green belt around the village strictly limits new building and larger replacement dwellings on the rural edge, so we resolve it on the page rather than leave it for the case officer to raise.
Allesley also carries protected streets — Allesley Village and Brownshill Green among them. Allesley (Bablake ward) sits outside the wards named in Coventry's citywide HMO Article 4 direction, so the usual householder permitted-development rights still apply — though works within the Allesley Village and Brownshill Green conservation areas remain controlled. We check your address against those designations before a line is drawn.

Many Allesley 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 Coventry City Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Coventry City 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 Coventry City Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Allesley approves most householder schemes, but the green-belt Coundon Wedge and the tightly-protected village conservation area are what constrain scale and siting on the rural edge. 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 Allesley Village, Brownshill Green and Allesley Park, 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 steep tiled and part-thatched roofs on the village cottages, that is usually the most efficient use of the roof; where the stock is hipped roofs on the interwar and post-war semis and detached homes, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The Allesley Village conservation area protects its cottage scale, materials and church setting in fine grain. 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 Coventry City 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 Allesley roofs come up most often:

The right loft in Allesley 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 Coventry City 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 Allesley Village and Brownshill Green and Article 4 directions can remove permitted-development rights.
A fixed process built around how Coventry City Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Allesley 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 Coventry City 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 Coventry City Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Coventry City 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 Allesley the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Allesley Village and Brownshill Green or on streets with an Article 4 direction. Coventry City Council is the decision-maker.
Generally no. In conservation areas including Allesley Village and Brownshill Green, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Coventry City Council. Allesley (Bablake ward) sits outside the wards named in Coventry's citywide HMO Article 4 direction, so the usual householder permitted-development rights still apply — though works within the Allesley Village and Brownshill Green conservation areas remain controlled. We check your exact address before drawing.
On steep tiled and part-thatched roofs on the village cottages, common across Allesley, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is hipped roofs on the interwar and post-war semis and detached homes, 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. Coventry City Council is the decision-maker.
A householder planning application in Allesley 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. Coventry City Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Coventry City 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 Allesley address specifically.
