Rear dormer drawings for Stivichall roofs — the box across the back slope that turns a low attic into a full-height room, drawn to Coventry City Council's guidance and the volume limits, delivered in days and revised free until your decision, with a free approval-odds check 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 tree-lined Kenilworth Road conservation area — protected in part through National Trust ownership of the verges — tightly limits bulk, roofs and boundary changes on its frontages, 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. Stivichall carries at least one Article 4 direction, and conservation areas including Kenilworth Road and London Road remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Stivichall is determined against an 8-week statutory target.
Styvechale (spacious interwar semis and detached homes south of War Memorial Park), Kenilworth Road (the avenue of large villas set behind the National Trust-owned tree belt, a conservation area), Green Lane (1930s semis on the western side of the district), Styvechale Grange (later detached estates toward the A45), Baginton fringe (green-edge plots on the southern boundary) and War Memorial Park edge (interwar houses fronting the city's largest park) — these are the Stivichall pockets our drawings cover most. Heritage designations here include Kenilworth Road and London Road. Coventry City Council weighs each proposal against the Coventry Local Plan (2017), where the generous interwar plots invite large extensions, but officers weigh their impact on the leafy, low-density suburban character. On roofs the borough is hipped roofs on the interwar semis and detached homes and steeper gables on the larger Kenilworth Road villas, over 1930s interwar detached and semi-detached houses, larger detached homes on the Kenilworth Road approach and post-war and later suburban infill.
The box dormer is the workhorse loft, and most of Stivichall is built for it — the borough runs to 1930s interwar detached and semi-detached houses, larger detached homes on the Kenilworth Road approach and post-war and later suburban infill under hipped roofs on the interwar semis and detached homes and steeper gables on the larger Kenilworth Road villas, and a flat-roofed box across the rear slope is the cheapest cubic metre of full-height space those roofs give up. Coventry City Council tests the dormer against the Coventry Local Plan (2017), and because permitted development turns on a number, the volume you propose against the volume you have left is the first thing an officer or a certificate checks.
That is why the arithmetic goes on the drawings. We calculate the box against the 40- or 50-cubic-metre allowance, count any earlier roof enlargement into the total, hold the flat roof below the ridge and set the face back off the eaves so the dormer reads as subordinate. The tree-lined Kenilworth Road conservation area — protected in part through National Trust ownership of the verges — tightly limits bulk, roofs and boundary changes on its frontages, so the cheeks, the window line and the material are drawn to answer it rather than invite a query.
Where Stivichall's streets are protected — Kenilworth Road and London Road among them — the Class B dormer right is switched off and even a modest rear box needs consent. Stivichall (also spelt Styvechale) sits in Wainbody ward, which is named in Coventry's citywide Article 4 direction (from 30 September 2023), so a house-to-small-HMO conversion requires a change-of-use application here. We confirm the designation before the box is sized.
Many rear dormers in Stivichall are permitted development, but the volume and position decide it. You will normally need a full application to Coventry City Council if any of these apply:
We draw the box within its volume allowance, the flat roof below the ridge and the face set back off the eaves — the three things a dormer stands or falls on — 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, drawn from official planning statistics and refreshed as new data lands. Stivichall approves most householder schemes, with the Kenilworth Road conservation area and the low-density interwar character setting the ceiling on roof and side additions. A dormer is decided on volume and set-back, so a pack that shows the calculation and the eaves detail is cleared faster and refused less often than a DIY submission.

Across Styvechale, Kenilworth Road and Green Lane, the dormer that goes through is the subordinate rear box: flat roof kept low, cheeks clad to recede, side windows obscure-glazed against overlooking, and the whole thing set back so the original eaves line still reads from the garden. On hipped roofs on the interwar semis and detached homes, this returns a full-height double and en-suite from what was standing-room-only, usually inside the permitted-development volume.
The generous interwar plots invite large extensions, but officers weigh their impact on the leafy, low-density suburban character. We keep the box off the ridge, match the cheek material to the roof, and where the volume is already spent — or the street is designated — draw the dormer as a householder application composed to Coventry City Council's roof-alteration guidance rather than push a certificate that would be refused.
We draw rear dormers on the terraced and semi-detached streets across the borough. A few of the neighbourhoods where Stivichall dormers come up most often:

Whether a dormer in Stivichall needs permission comes down to where it sits and how big the box is. This is how the cases compare.
| Dormer type | Permitted development? | What it gains | What Coventry City Council checks |
|---|---|---|---|
| Rear box, within volume | Usually yes | Full-height room across the back | Volume total, 20cm eaves set-back |
| Rear box, over volume limit | No — full application | A larger room | How far over the allowance, bulk |
| Front or side dormer | No — full application | Light to the front rooms | Visibility from the street, character |
| Dormer in a conservation area | No — full application | Same space, extra scrutiny | Roof form and street appearance |
In conservation areas such as Kenilworth Road and London Road, Class B dormer rights are removed and every dormer needs a full application.
A fixed process built around how Coventry City Council validates and decides dormer applications — most drawings are submission-ready within seven days of survey.
Send us your Stivichall postcode and roof type. We confirm your conservation and Article 4 status, work out 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 and the existing loft floor — the numbers the volume calculation, the set-back and the head heights depend on.
Chartered designers develop the box to your brief, drawn inside the Class B volume limits or, where those are exhausted or removed, 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 box dormer within 40 cubic metres on a terrace, or 50 on a semi or detached house, set back at least 20 centimetres from the eaves and kept below the ridge, is usually permitted development. In Stivichall you will need a full application to Coventry City Council for a front or side dormer, a box that exceeds the volume, and any dormer in a conservation area such as Kenilworth Road and London Road, where those rights are removed.
The permitted-development limit is a volume, not a footprint: 40 cubic metres of added roof space on a terraced house and 50 on a semi-detached or detached one, and any earlier loft enlargement counts against that total. In Stivichall the box must also sit below the ridge and back from the eaves. We measure your roof and calculate the exact volume you have left before drawing. Coventry City Council is the decision-maker.
Not under permitted development. A dormer on the front roof slope, or one facing a highway, always needs a full application to Coventry City Council, because it changes how the house reads from the street. Rear box dormers are far more likely to be approved — or to be permitted development outright — which is why almost every Stivichall dormer we draw sits on the back slope.
Often, on a terrace or semi. If the dormer or the loft steelwork meets the party wall with your neighbour, the Party Wall etc. Act applies and notice must be served before work starts — separately from Coventry City Council's planning decision. We flag the party-wall junction on the drawings so a surveyor can be appointed early and the build is not held up. This applies to your Stivichall address specifically.
If your dormer is permitted development, a lawful development certificate from Coventry City Council is council-stamped proof of it — worth holding, because a buyer's solicitor will ask for it when you sell. We prepare and submit the certificate with the same measured drawing pack that shows the box within its volume allowance. This applies to your Stivichall address specifically.
We price each Stivichall dormer individually, because the roof pitch and the volume left 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 Coventry City Council approves, and we confirm at the outset whether your box is permitted development or needs an application.
