Rear dormer drawings for Clarendon Park roofs — the box across the back slope that turns a low attic into a full-height room, drawn to Leicester City Council's guidance and the volume 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 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 box dormer is the workhorse loft, and most of Clarendon Park is built for it — the borough runs to 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 under gabled and hipped slate roofs on the terraces and rear back-addition roofs shaping side-return schemes, and a flat-roofed box across the rear slope is the cheapest cubic metre of full-height space those roofs give up. Leicester City Council tests the dormer against the Leicester Local Plan and the council's Student Housing SPD, and because permitted development turns on a number, the volume you propose against the volume you have left is the first thing an officer or a certificate checks.
That is why the arithmetic goes on the drawings. We calculate the box against the 40- or 50-cubic-metre allowance, count any earlier roof enlargement into the total, hold the flat roof below the ridge and set the face back off the eaves so the dormer reads as subordinate. 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, so the cheeks, the window line and the material are drawn to answer it rather than invite a query.
Where Clarendon Park's streets are protected — Stoneygate, New Walk and Knighton among them — the Class B dormer right is switched off and even a modest rear box needs consent. 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. We confirm the designation before the box is sized.
Many rear dormers in Clarendon Park are permitted development, but the volume and position decide it. You will normally need a full application to Leicester City Council if any of these apply:
We draw the box within its volume allowance, the flat roof below the ridge and the face set back off the eaves — the three things a dormer stands or falls on — 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, 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. A dormer is decided on volume and set-back, so a pack that shows the calculation and the eaves detail is cleared faster and refused less often than a DIY submission.

Across Queens Road, Montague Road and Springfield Road, the dormer that goes through is the subordinate rear box: flat roof kept low, cheeks clad to recede, side windows obscure-glazed against overlooking, and the whole thing set back so the original eaves line still reads from the garden. On gabled and hipped slate roofs on the terraces, this returns a full-height double and en-suite from what was standing-room-only, usually inside the permitted-development volume.
The Stoneygate conservation area boundary reaches into Clarendon Park, so frontage, boundary-wall and roof detail are held to conservation standards on those streets. We keep the box off the ridge, match the cheek material to the roof, and where the volume is already spent — or the street is designated — draw the dormer as a householder application composed to Leicester City Council's roof-alteration guidance rather than push a certificate that would be refused.
We draw rear dormers on the terraced and semi-detached streets across the borough. A few of the neighbourhoods where Clarendon Park dormers come up most often:

Whether a dormer in Clarendon Park needs permission comes down to where it sits and how big the box is. This is how the cases compare.
| Dormer type | Permitted development? | What it gains | What Leicester City Council checks |
|---|---|---|---|
| Rear box, within volume | Usually yes | Full-height room across the back | Volume total, 20cm eaves set-back |
| Rear box, over volume limit | No — full application | A larger room | How far over the allowance, bulk |
| Front or side dormer | No — full application | Light to the front rooms | Visibility from the street, character |
| Dormer in a conservation area | No — full application | Same space, extra scrutiny | Roof form and street appearance |
In conservation areas such as Stoneygate and New Walk, Class B dormer rights are removed and every dormer needs a full application.
A fixed process built around how Leicester City Council validates and decides dormer applications — most drawings are submission-ready within seven days of survey.
Send us your Clarendon Park postcode and roof type. We confirm your conservation and Article 4 status, work out 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 and the existing loft floor — the numbers the volume calculation, the set-back and the head heights depend on.
Chartered designers develop the box to your brief, drawn inside the Class B volume limits or, where those are exhausted or removed, 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 box dormer within 40 cubic metres on a terrace, or 50 on a semi or detached house, set back at least 20 centimetres from the eaves and kept below the ridge, is usually permitted development. In Clarendon Park you will need a full application to Leicester City Council for a front or side dormer, a box that exceeds the volume, and any dormer in a conservation area such as Stoneygate and New Walk, where those rights are removed.
The permitted-development limit is a volume, not a footprint: 40 cubic metres of added roof space on a terraced house and 50 on a semi-detached or detached one, and any earlier loft enlargement counts against that total. In Clarendon Park the box must also sit below the ridge and back from the eaves. We measure your roof and calculate the exact volume you have left before drawing. Leicester City Council is the decision-maker.
Not under permitted development. A dormer on the front roof slope, or one facing a highway, always needs a full application to Leicester City Council, because it changes how the house reads from the street. Rear box dormers are far more likely to be approved — or to be permitted development outright — which is why almost every Clarendon Park dormer we draw sits on the back slope.
Often, on a terrace or semi. If the dormer or the loft steelwork meets the party wall with your neighbour, the Party Wall etc. Act applies and notice must be served before work starts — separately from Leicester City Council's planning decision. We flag the party-wall junction on the drawings so a surveyor can be appointed early and the build is not held up. This applies to your Clarendon Park address specifically.
If your dormer is permitted development, a lawful development certificate from Leicester City Council is council-stamped proof of it — worth holding, because a buyer's solicitor will ask for it when you sell. We prepare and submit the certificate with the same measured drawing pack that shows the box within its volume allowance. This applies to your Clarendon Park address specifically.
We price each Clarendon Park dormer individually, because the roof pitch and the volume left vary house to house, 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 box is permitted development or needs an application.
