Single-storey, double-storey, rear and side extension drawings for Stoneygate homes — measured to Leicester City Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
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 homes come in a handful of recurring shapes, and each one points to a different extension. 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, so a Victorian terrace usually wants a rear or side-return infill, while an interwar semi has room for a wider single-storey wrap or a two-storey side addition. Leicester City Council judges every one of them against the Leicester Local Plan and the Stoneygate Conservation Area Character Appraisal, weighing footprint, height and the impact on the house next door before it looks at the elevations.
That is why the drawings decide the outcome. We set the extension depth against the permitted-development limits precisely, keep the eaves and ridge within the allowances, and plot the 45-degree daylight lines to the neighbours' windows so the case officer can see the amenity test is passed. 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 design around it from the first sketch rather than discover it at validation.
Stoneygate also protects whole 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. On designated land the larger-home extension route and most side extensions stop being permitted development, so we confirm your address against those layers before drawing a line.
Plenty of Stoneygate extensions are permitted development and need no planning application — a single-storey rear extension within the depth and height limits is the common case. You will normally need to apply to Leicester City Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Leicester City Council's officers weigh first — and submit a validation-complete pack, whether that is a lawful development certificate, a prior-approval notification or a full householder application.
Below is Leicester City Council's real householder decision record, drawn from official planning statistics and refreshed 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. A complete, policy-literate extension pack anticipates those pressure points before submission, which is why professionally drawn applications are decided faster and refused less often than DIY ones.

Across London Road, Ratcliffe Road and Springfield Road, the extension that lands most often is the single-storey rear addition — a glazed kitchen-diner across the back of the house, kept within the permitted-development depth or taken to a full application where the ground floor wants more. On the borough's grand victorian and edwardian villas on generous plots, a side-return infill frequently pairs with it to square off the plan; on wider later mansion flats and infill apartments, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The HMO Article 4 Direction restricts subdivision of the large family houses into student lets and small HMOs. We size the extension to the amenity and daylight tests, match the roof and materials to the host house, and keep enough garden to satisfy Leicester City Council's space standards — so the scheme answers the borough's questions before an objection can raise them. Where permitted-development rights are used up or removed, we prepare the householder application to the council's extension design guidance instead.
We draw extensions on every street in the borough. A few of the neighbourhoods where Stoneygate projects come up most often:

The right extension in Stoneygate depends on your house type and how much garden you can give up. This is how the main options compare on planning route and what they add.
| Extension type | Permitted development? | What it adds | What Leicester City Council checks |
|---|---|---|---|
| Single-storey rear | Often, within 3m/4m depth (6m/8m via prior approval) | Bigger kitchen-diner across the back | Depth, height, neighbour daylight (45°) |
| Side-return infill | Sometimes, if within width and height limits | Squares off an L-shaped ground floor | Width vs the original house, glazing to boundary |
| Two-storey rear/side | No — full application | Extra bedroom or bathroom above | Bulk, overlooking, 7m rear-boundary gap |
| Wraparound (rear + side) | No — full application | Whole-width open-plan ground floor | Combined footprint and garden retained |
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 extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Stoneygate postcode and house type. We confirm your conservation and Article 4 status, how much permitted-development depth you have left, and score your odds against live Leicester City Council decisions.
We measure the existing footprint, floor and eaves levels, boundary distances and the neighbours' window positions — the numbers the depth limits and daylight tests depend on.
Chartered designers develop the single-storey, two-storey or side extension to your brief, drawn inside the permitted-development limits or to Leicester City Council's extension design guidance.
We submit the certificate, prior-approval notice or application, manage validation and case-officer queries, and revise the drawings free until Leicester City Council issues its decision.
Not always. A single-storey rear extension up to 3 metres deep on a terrace or semi, or 4 metres on a detached house, and no higher than 4 metres, is usually permitted development. In Stoneygate you will need to apply to Leicester City Council for two-storey extensions, side extensions wider than half the house, anything forward of the front wall, deeper rear extensions under the larger-home prior-approval route, and any extension in a conservation area such as Stoneygate and Ashleigh Road.
Standard permitted development allows 3 metres on a terraced or semi-detached house and 4 metres on a detached one. The larger-home extension scheme can double that to 6 or 8 metres, but it needs a prior-approval notification to Leicester City Council and a neighbour-consultation period, and it does not apply on designated land such as Stoneygate's conservation areas. We confirm which route your property qualifies for before drawing.
Two-storey and double-storey extensions almost always need a full householder application to Leicester City Council, because they fall outside permitted development on most homes. The council looks closely at bulk, overlooking of neighbours and the 7-metre gap a two-storey rear extension must keep from the rear boundary. We design to those tests and show the daylight and privacy angles on the drawings. This applies to your Stoneygate address specifically.
A householder planning application in Stoneygate runs to a statutory eight-week target, a larger-home prior-approval notification to around six weeks including the neighbour-consultation period, and a lawful development certificate to eight weeks. Incomplete submissions stall at validation, so we submit a complete pack and manage officer queries to keep the decision on schedule. Leicester City Council is the decision-maker.
Yes — planning permission and building regulations are separate consents, and almost every extension needs both. Planning governs whether you can build it; building control governs how it is built, covering structure, insulation, drainage and fire safety. We prepare the building-regulations drawings alongside the planning set so Leicester City Council's building control or an approved inspector can sign the work off. This applies to your Stoneygate address specifically.
Every house and brief is different, so we price each Stoneygate extension individually and send a fixed, no-obligation quote back within one working day. It covers the full drawing pack with free revisions until Leicester City Council approves, and we tell you upfront whether your extension qualifies as permitted development.
