The fast route to a deep single-storey rear extension in Clarendon Park — up to 6 metres on an attached house or 8 on a detached one — via Leicester City Council's prior approval scheme rather than a full planning application.
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 means any new small HMO needs consent, and the council usually refuses further conversions where student occupation is already concentrated, 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. Clarendon Park carries at least one Article 4 direction, and conservation areas including Stoneygate, New Walk and Knighton remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Clarendon Park is determined against an 8-week statutory target.
Queens Road (the shopping spine framed by tightly packed Edwardian terraces), Montague Road (grid of red-brick terraces with front bays and small forecourts), Springfield Road (wider terraces edging into the Stoneygate conservation area), Howard Road (student-dominated terraced streets close to the University of Leicester), Avenue Road Extension (later terraces linking Clarendon Park to Knighton) and Clarendon Park Road (the district's namesake terraced street of period frontages) — these are the Clarendon Park pockets our drawings cover most. Heritage designations here include Stoneygate, New Walk and Knighton. Leicester City Council weighs each proposal against the Leicester Local Plan and the council's Student Housing SPD, where the Stoneygate conservation area boundary reaches into Clarendon Park, so frontage, boundary-wall and roof detail are held to conservation standards on those streets. Many Clarendon Park terraces are subdivided into student flats or run as HMOs, and converted flats hold no householder permitted-development rights.. On roofs the borough is gabled and hipped slate roofs on the terraces and rear back-addition roofs shaping side-return schemes, over late-Victorian and Edwardian red-brick terraces, larger bay-fronted villas towards the Stoneygate edge and period houses widely converted to student flats and HMOs.
The ordinary Class A limits stop a single-storey rear extension at 3 metres on an attached house and 4 on a detached one. The larger home extension scheme doubles both, on condition that the council is told first. That notification is not an application for permission — the council cannot refuse on design, materials or policy grounds. It can only consider the effect on the amenity of adjoining premises, and only if a neighbour actually objects during the 21-day consultation.
The other conditions still apply and are strict: single storey only, no higher than 4 metres, eaves no higher than the existing eaves, and no more than half the land around the original house covered. It is not available on designated land, so a house in a conservation area such as Stoneygate and New Walk cannot use it at all. Materials must be similar to the existing house, and the extension must not include a veranda, balcony or raised platform.
Clarendon Park is largely late-Victorian and Edwardian red-brick terraces, larger bay-fronted villas towards the Stoneygate edge and period houses widely converted to student flats and HMOs. The HMO Article 4 Direction means any new small HMO needs consent, and the council usually refuses further conversions where student occupation is already concentrated, which matters here because an objecting neighbour puts amenity squarely in front of a case officer. Clarendon Park sits at the heart of Leicester's HMO Article 4 area, first introduced in 2013 and extended in 2022, so converting a family house to a small house in multiple occupation needs planning permission and is routinely refused near the universities.
The scheme is available where all of these hold. Fail any one and it is a full application to Leicester City Council instead:
We prepare the notification pack Leicester City Council needs — plans, elevations, a site plan with the adjoining owners identified — and manage the 21-day neighbour consultation so the 42-day clock is not restarted by an incomplete submission.
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 Clarendon Park the defining tension is intense student-HMO demand meeting the Article 4 controls that restrict further conversions. Prior approval turns on neighbour amenity alone, so the drawings that matter are the ones showing the relationship to the boundary.

Across Queens Road, Montague Road and Springfield Road, the notifications that clear without objection are the ones that treat the neighbour as the audience. We show the extension in section against the boundary, demonstrate the 45-degree daylight relationship to the nearest habitable window, and where the plot is tight we taper the depth away from the boundary rather than running the full 6 metres to the fence.
The Stoneygate conservation area boundary reaches into Clarendon Park, so frontage, boundary-wall and roof detail are held to conservation standards on those streets. Where an objection does arrive, the council's assessment is narrow: loss of light, outlook and overbearing effect on the adjoining property, nothing else. A pack that has already answered those three points on the drawings usually survives an objection, whereas one that leaves them to the officer's imagination usually does not.
We prepare prior-approval notifications across Clarendon Park. A few of the areas where deep rear extensions come up most often:
Prior approval drawings for Queens Road — the shopping spine framed by tightly packed Edwardian terraces — dimensioned to the 6m and 8m limits and prepared for Leicester City Council's neighbour consultation.
Prior approval drawings for Montague Road — grid of red-brick terraces with front bays and small forecourts — dimensioned to the 6m and 8m limits and prepared for Leicester City Council's neighbour consultation.
Prior approval drawings for Springfield Road — wider terraces edging into the Stoneygate conservation area — dimensioned to the 6m and 8m limits and prepared for Leicester City Council's neighbour consultation.
Prior approval drawings for Howard Road — student-dominated terraced streets close to the University of Leicester — dimensioned to the 6m and 8m limits and prepared for Leicester City Council's neighbour consultation.
Prior approval drawings for Avenue Road Extension — later terraces linking Clarendon Park to Knighton — dimensioned to the 6m and 8m limits and prepared for Leicester City Council's neighbour consultation.
Prior approval drawings for Clarendon Park Road — the district's namesake terraced street of period frontages — dimensioned to the 6m and 8m limits and prepared for Leicester City Council's neighbour consultation.
Same extension, two routes, very different tests.
| Route | Depth allowed | What the council may consider | Timescale |
|---|---|---|---|
| Ordinary Class A permitted development | 3m attached / 4m detached | Nothing — no application needed | Immediate |
| Larger home extension prior approval | 6m attached / 8m detached | Amenity of adjoining premises, only if a neighbour objects | 21-day consultation, 42-day determination |
| Full householder application | No fixed limit | Design, materials, policy, amenity, everything | 8-week target |
| Any of these on designated land | 3m / 4m only | Prior approval scheme unavailable | Full application beyond the limits |
Limits and procedure from the GPDO 2015, Schedule 2, Part 1, Class A and paragraph A.4, made permanent by amendment in 2019.
A process built around the 21-day consultation, which is where these schemes are won or lost.
Send us your Clarendon Park postcode and house type. We confirm whether the property is on designated land, whether the scheme is available, and what depth you can realistically take.
We measure the original rear wall, eaves height, boundary distances and the neighbouring windows that the amenity assessment will turn on.
We draw the extension to the 6m or 8m limit with the boundary relationship shown in section, and prepare the written description and adjoining-owner details Leicester City Council needs to start the consultation.
We submit, track the 21-day consultation and the 42-day determination, respond to any objection on amenity grounds, and revise free until the decision.
Three metres on a terraced or semi-detached house and four on a detached one under ordinary permitted development. Under the larger home extension prior approval scheme those double to six and eight metres, provided you notify Leicester City Council before starting and the conditions on height, materials and land coverage are met. The scheme is not available on designated land. This applies to your Clarendon Park address specifically.
It is a notification, not an application for permission. You tell Leicester City Council what you intend to build, it writes to the adjoining owners, and they have 21 days to object. If nobody objects, you may build. If someone does, the council assesses the effect on the amenity of adjoining premises and must decide within 42 days. Design and policy are not in scope. This applies to your Clarendon Park address specifically.
The council then considers the impact on the amenity of the adjoining property — loss of light, loss of outlook, and overbearing effect — and nothing else. It cannot refuse because it dislikes the design or the materials. We prepare the drawings so those three questions are already answered in section and on the site plan, which is what usually carries an objected scheme through. This applies to your Clarendon Park address specifically. Leicester City Council is the decision-maker.
No. The larger home extension scheme is unavailable on designated land, which includes conservation areas such as Stoneygate and New Walk, national landscapes, national parks and world heritage sites. On those properties the ordinary 3-metre and 4-metre limits apply, and anything deeper needs a full householder application to Leicester City Council. This applies to your Clarendon Park address specifically.
Twenty-one days for the neighbour consultation, and a maximum of 42 days from a valid submission for the council to determine it. If the council does not respond within 42 days you may proceed as notified. That deadline is the scheme's real advantage over a full application, and it is why validation completeness matters so much. This applies to your Clarendon Park address specifically. Leicester City Council is the decision-maker.
Yes — always. Prior approval deals only with the planning position. A 6-metre rear extension still needs building control approval for foundations, structure, drainage, thermal performance and fire safety, and the beam over the opening into the existing house needs designing and calculating. We prepare both sets so the notified scheme is the buildable one. This applies to your Clarendon Park address specifically. Leicester City Council is the decision-maker.
