Dormer, hip-to-gable and mansard loft conversion drawings for Stoneygate homes — prepared to Leicester City Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Leicester City Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. Stoneygate is Leicester's best-preserved Victorian and Edwardian suburb, so extensions are judged against the character appraisal's protection of villa plots, boundary walls and mature trees, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and Edwardian (1901–1910) 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. Stoneygate carries at least one Article 4 direction, and conservation areas including Stoneygate, Ashleigh Road and Knighton remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Stoneygate is determined against an 8-week statutory target.
London Road (the tree-lined approach fronted by substantial period villas), Ratcliffe Road (large detached houses in mature garden plots), Springfield Road (gothic and arts-and-crafts villas within the conservation area), Elms Road (handsome Edwardian houses close to the Ashleigh Road boundary), Knighton Park Road (villas edging Knighton Park and the parkland fringe) and St John's (the church quarter of Victorian merchant houses) — these are the Stoneygate pockets our drawings cover most. Heritage designations here include Stoneygate, Ashleigh Road, Knighton and New Walk. Leicester City Council weighs each proposal against the Leicester Local Plan and the Stoneygate Conservation Area Character Appraisal, where the HMO Article 4 Direction restricts subdivision of the large family houses into student lets and small HMOs. Several of the larger villas have been split into flats or mansion apartments, and converted flats carry no householder permitted-development rights.. On roofs the borough is steep gabled slate and clay-tile roofs with ornate ridge detail and hipped roofs on the larger detached villas, over grand Victorian and Edwardian villas on generous plots, arts-and-crafts and gothic-revival detached houses and later mansion flats and infill apartments.
Stoneygate's roofs set the brief. The borough is built largely from grand Victorian and Edwardian villas on generous plots, arts-and-crafts and gothic-revival detached houses and later mansion flats and infill apartments, and its lofts sit under steep gabled slate and clay-tile roofs with ornate ridge detail and hipped roofs on the larger detached villas — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Leicester City Council assesses loft proposals against the Leicester Local Plan and the Stoneygate Conservation Area Character Appraisal, 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 Leicester City Council can verify them. Stoneygate is Leicester's best-preserved Victorian and Edwardian suburb, so extensions are judged against the character appraisal's protection of villa plots, boundary walls and mature trees, so we resolve it on the page rather than leave it for the case officer to raise.
Stoneygate also carries protected streets — Stoneygate, Ashleigh Road, Knighton and New Walk among them. The 2022 extension of Leicester's HMO Article 4 Direction pulled much of Stoneygate into the controlled area, so new houses in multiple occupation need planning permission alongside the conservation controls that already cover the suburb. We check your address against those designations before a line is drawn.

Many Stoneygate 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 Leicester 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 Leicester 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 Leicester City Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Leicester grants the large majority of householder applications, though in Stoneygate the conservation status of the villa suburb and pressure to subdivide big houses are the recurring constraints. 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 London Road, Ratcliffe Road and Springfield Road, 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 gabled slate and clay-tile roofs with ornate ridge detail, that is usually the most efficient use of the roof; where the stock is hipped roofs on the larger detached villas, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The HMO Article 4 Direction restricts subdivision of the large family houses into student lets and small HMOs. 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 Leicester 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 Stoneygate roofs come up most often:

The right loft in Stoneygate 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 Leicester 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 Stoneygate and Ashleigh Road and Article 4 directions can remove permitted-development rights.
A fixed process built around how Leicester City Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Stoneygate 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 Leicester 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 Leicester City Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Leicester 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 Stoneygate the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Stoneygate and Ashleigh Road or on streets with an Article 4 direction. Leicester City Council is the decision-maker.
Generally no. In conservation areas including Stoneygate and Ashleigh Road, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Leicester City Council. The 2022 extension of Leicester's HMO Article 4 Direction pulled much of Stoneygate into the controlled area, so new houses in multiple occupation need planning permission alongside the conservation controls that already cover the suburb. We check your exact address before drawing.
On steep gabled slate and clay-tile roofs with ornate ridge detail, common across Stoneygate, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is hipped roofs on the larger detached villas, 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. Leicester City Council is the decision-maker.
A householder planning application in Stoneygate 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. Leicester City Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Leicester 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 Stoneygate address specifically.
Every roof is different, so we quote each Stoneygate project individually — a fixed, no-obligation price back within one working day.
