Single-storey, double-storey, rear and side extension drawings for Highfields 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. The HMO Article 4 Direction covers much of Highfields, so new small-HMO conversions need consent and are commonly refused where occupation is already dense, 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. Highfields carries at least one Article 4 direction, and conservation areas including South Highfields, Spinney Hill Park and New Walk remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Highfields is determined against an 8-week statutory target.
South Highfields (the conservation area of grand three-storey Victorian townhouses), Spinney Hills (dense terraced streets framing Spinney Hill Park), St Peter's (tightly packed Victorian terraces near the city edge), Melbourne Road (the diverse terraced spine of shops and housing), Sparkenhoe (Victorian terraces around the historic school streets) and Evington Road (terraces and townhouses linking Highfields to Evington) — these are the Highfields pockets our drawings cover most. Heritage designations here include South Highfields, Spinney Hill Park and New Walk. Leicester City Council weighs each proposal against the Leicester Local Plan and the South Highfields conservation area appraisal, where the South Highfields conservation area protects grand three-storey townhouse frontages, holding extension and roof detail to heritage standards. A large share of Highfields terraces and townhouses are subdivided into flats or run as HMOs, and converted flats hold no householder permitted-development rights.. On roofs the borough is gabled slate roofs on the terraces and parapet and rear-addition roofs on the taller townhouses, over dense Victorian and Edwardian red-brick terraces, larger three-storey townhouses in South Highfields and period houses widely converted to flats and HMOs.
Highfields homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from dense Victorian and Edwardian red-brick terraces, larger three-storey townhouses in South Highfields and period houses widely converted to flats and HMOs, 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 South Highfields conservation area 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. The HMO Article 4 Direction covers much of Highfields, so new small-HMO conversions need consent and are commonly refused where occupation is already dense, so we design around it from the first sketch rather than discover it at validation.
Highfields also protects whole streets — South Highfields, Spinney Hill Park and New Walk among them. Highfields lies within Leicester's HMO Article 4 area — the 2022 extension added much of Spinney Hills and Highfields — so converting family homes to small HMOs needs planning permission, alongside the South Highfields conservation-area controls. 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 Highfields 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, but in Highfields the HMO Article 4 controls and the South Highfields townhouse conservation area are the defining 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 South Highfields, Spinney Hills and St Peter's, 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 dense victorian and edwardian red-brick terraces, a side-return infill frequently pairs with it to square off the plan; on wider period houses widely converted to flats and hmos, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The South Highfields conservation area protects grand three-storey townhouse frontages, holding extension and roof detail to heritage standards. 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 Highfields projects come up most often:

The right extension in Highfields 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 South Highfields and Spinney Hill Park 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 Highfields 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 Highfields 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 South Highfields and Spinney Hill Park.
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 Highfields'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 Highfields address specifically.
A householder planning application in Highfields 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 Highfields address specifically.
Every house and brief is different, so we price each Highfields extension individually and send a fixed, no-obligation quote back within one working day.
