Back-of-house extension drawings for Westcotes homes — the glazed kitchen-diner across the rear, drawn to Leicester City Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check 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. The West End Article 4 Direction removes permitted-development rights across the whole conservation area, so frontage, window and roof changes need consent, 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. Westcotes carries at least one Article 4 direction, and conservation areas including West End, Braunstone and Aylestone village remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Westcotes is determined against an 8-week statutory target.
Westcotes Drive (the tree-lined avenue of bay-fronted Edwardian terraces), Narborough Road (the busy shopping spine framed by dense terraced streets), Braunstone Gate (the West End edge of shops, bars and period frontages), Hinckley Road (terraces and villas along the western approach), Harrow Road (well-preserved red-brick terraces within the conservation area) and Fosse Road (wider Victorian terraces near the recreation grounds) — these are the Westcotes pockets our drawings cover most. Heritage designations here include West End, Braunstone and Aylestone village. Leicester City Council weighs each proposal against the Leicester Local Plan and the West End Conservation Area Character Appraisal, where the terraces are held to detailed material and sash-window standards to preserve the red-brick Victorian character. Many Westcotes terraces are split into flats or student lets, and converted flats carry no householder permitted-development rights.. On roofs the borough is gabled slate roofs on the red-brick terraces and rear back-addition roofs shaping side-return schemes, over late-Victorian and Edwardian red-brick terraces, bay-fronted houses with original sash windows and slate roofs and terraces widely converted to flats and student lets near the university.
The rear extension is the workhorse of Westcotes home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from late-Victorian and Edwardian red-brick terraces, bay-fronted houses with original sash windows and slate roofs and terraces widely converted to flats and student lets near the university, most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Leicester City Council scrutinises. The council reads the proposal against the Leicester Local Plan and the West End Conservation Area Character Appraisal, and the first line an officer draws is the 45-degree splay from the neighbour's nearest window.
So the drawings live or die on geometry. We set the depth against the exact permitted-development figure, hold the eaves and the flat-roof or lantern build-up under the 4-metre height ceiling, and show the projection tested against both the 45-degree plan angle and the 25-degree section angle to the neighbouring windows. The West End Article 4 Direction removes permitted-development rights across the whole conservation area, so frontage, window and roof changes need consent, so the rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — West End, Braunstone and Aylestone village among Westcotes's — the larger-home extension route is switched off and even a modest rear addition needs consent. The West End conservation area covering the Westcotes streets carries a June 2022 Article 4 Direction — replacing the earlier Daneshill and Westcotes Drive directions — that removes permitted-development rights across the whole area to protect its terraced character. We confirm the designation before the survey.
Many single-storey rear extensions in Westcotes are permitted development and need no application. You will normally need to apply to Leicester City Council, or use the larger-home prior-approval route, if any of these apply:
We draw the depth, the roof build-up and the daylight splays to each neighbour on the page — the tests Leicester City Council's officers apply first — and submit a validation-complete pack, whether that is a lawful development certificate, a larger-home prior-approval notice or a full householder application.
Below is Leicester City Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Leicester grants the large majority of householder applications, but in Westcotes the West End conservation-area Article 4 controls and student-let pressure are the defining constraints. Rear extensions turn most often on neighbour daylight and depth, so a drawing pack that proves those tests upfront is decided faster and refused less often than a DIY submission.

Across Westcotes Drive, Narborough Road and Braunstone Gate, the approved rear extension is typically a single-storey glazed box within the depth limit, roofed either flat with a lantern or in a shallow mono-pitch, and finished in brick or render to match the host wall. On the borough's late-victorian and edwardian red-brick terraces, keeping the projection to the permitted-development figure often avoids an application entirely; where owners want the full 6 metres, the larger-home route succeeds when the neighbour-consultation period passes without a sustained objection.
The terraces are held to detailed material and sash-window standards to preserve the red-brick Victorian character. We keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Leicester City Council expects — so the back elevation answers the amenity case before a neighbour can lodge one. Two-storey rear extensions we draw with the 7-metre boundary gap and privacy screening resolved on the plan.
We draw rear extensions on every street in the borough. A few of the neighbourhoods where Westcotes back-of-house projects come up most often:

How far you can extend at the back in Westcotes depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Leicester City Council checks |
|---|---|---|---|
| Standard permitted development | 3m terrace/semi · 4m detached | Lawful development certificate (optional) | Depth, 4m height, materials |
| Larger-home prior approval | 6m terrace/semi · 8m detached | Prior-approval notice + neighbour consultation | Neighbour objections on amenity |
| Full householder application | Beyond the above, or two-storey | Full planning permission | Daylight (45°/25°), bulk, garden retained |
| Conservation area | Case by case | Full planning permission | Character, roof form, boundary treatment |
The larger-home route is switched off on designated land — conservation areas such as West End and Braunstone and Article 4 streets need a full application.
A fixed process built around how Leicester City Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Westcotes postcode and house type. We confirm your conservation and Article 4 status, how much rear-extension depth you have under permitted development, and score your odds against live Leicester City Council decisions.
We measure the original rear wall, floor and eaves levels, side and rear boundary distances and the neighbours' window positions — the numbers the depth limit and daylight splays depend on.
Chartered designers develop the single or two-storey rear extension to your brief, drawn inside the permitted-development limits or to Leicester City Council's extension design guidance, with the daylight angles shown.
We submit the certificate, prior-approval notice or application, handle validation and case-officer queries, and revise the drawings free until Leicester City Council issues its decision.
Often not. 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 Westcotes. You will need to involve Leicester City Council for anything deeper via the larger-home route, for two-storey rear extensions, and for any rear extension in a conservation area such as West End and Braunstone, where those permitted-development rights fall away.
The larger-home extension scheme lets a single-storey rear extension reach 6 metres on a terrace or semi, or 8 metres on a detached house — double the standard allowance. It is not automatic: you submit a prior-approval notification to Leicester City Council, neighbours are consulted, and if one objects on amenity grounds the council rules on it. It also does not apply on designated land such as Westcotes's conservation areas.
It is the daylight test Leicester City Council applies to protect neighbours. Drawn on plan, a line at 45 degrees from the midpoint of the neighbour's nearest ground-floor window should not be crossed by your extension; a companion 25-degree line is checked in section. If the projection breaches it, the extension is likely to be shortened or refused, so we test and prove it on the drawings before submission. This applies to your Westcotes address specifically.
A two-storey rear extension almost always needs a full householder application to Leicester City Council, as it sits outside permitted development on most homes. The council checks that it stays at least 7 metres from the rear boundary, does not overbear the neighbours and avoids new overlooking. We resolve the boundary gap, privacy and daylight on the plans so the application is decided on its merits. This applies to your Westcotes address specifically.
Frequently, yes. If the rear extension involves work to a shared wall, building up to the boundary, or excavating foundations near a neighbour's structure, the Party Wall etc. Act applies and you must serve notice — this is separate from Leicester City Council's planning decision. We flag it early and can prepare the drawings a party-wall surveyor needs alongside the planning set. This applies to your Westcotes address specifically.
We price each Westcotes rear extension on its own footprint and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Leicester City Council approves, and we confirm at the outset whether your extension is permitted development, needs prior approval, or a full application.
