Rear dormer drawings for Aylestone 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 Aylestone village conservation area protects the historic core, its cottages and the medieval packhorse bridge setting, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. Aylestone carries at least one Article 4 direction, and conservation areas including Aylestone village, Braunstone and West End remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Aylestone is determined against an 8-week statutory target.
Aylestone Village (the historic core with the conservation area, packhorse bridge and old church), Saffron Lane (interwar and postwar estate housing to the east), Lutterworth Road (suburban semis lining the southern approach), Grace Road (terraces and semis near the cricket ground), Kirkdale Road (denser Victorian and interwar streets towards the city) and Middleton Street (terraced housing edging the meadows and canal) — these are the Aylestone pockets our drawings cover most. Heritage designations here include Aylestone village, Braunstone and West End. Leicester City Council weighs each proposal against the Leicester Local Plan and the Aylestone Village conservation area appraisal, where much of the southern suburb is interwar and postwar semis policed for spacing and paired-house rhythm on extensions. On roofs the borough is hipped roofs on the interwar and postwar semis and gabled slate roofs on the older village and terraced houses, over interwar and postwar semi-detached houses with gardens, Victorian terraces on the streets nearer the city and older village cottages around the historic core.
The box dormer is the workhorse loft, and most of Aylestone is built for it — the borough runs to interwar and postwar semi-detached houses with gardens, Victorian terraces on the streets nearer the city and older village cottages around the historic core under hipped roofs on the interwar and postwar semis and gabled slate roofs on the older village and terraced houses, 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 Aylestone Village conservation area appraisal, 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 Aylestone village conservation area protects the historic core, its cottages and the medieval packhorse bridge setting, so the cheeks, the window line and the material are drawn to answer it rather than invite a query.
Where Aylestone's streets are protected — Aylestone village, Braunstone and West End among them — the Class B dormer right is switched off and even a modest rear box needs consent. The 2022 HMO Article 4 extension reached part of Aylestone, so new small-HMO conversions there need planning permission, while the Aylestone village conservation area adds heritage controls around the historic core. We confirm the designation before the box is sized.

Many rear dormers in Aylestone 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, and in Aylestone the historic village conservation area and the protected semi-detached suburban streets shape most schemes. 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 Aylestone Village, Saffron Lane and Lutterworth 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 hipped roofs on the interwar and postwar semis, this returns a full-height double and en-suite from what was standing-room-only, usually inside the permitted-development volume.
Much of the southern suburb is interwar and postwar semis policed for spacing and paired-house rhythm on extensions. 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 Aylestone dormers come up most often:

Whether a dormer in Aylestone 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 Aylestone village and Braunstone, 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 Aylestone 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 Aylestone 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 Aylestone village and Braunstone, 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 Aylestone 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 Aylestone 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 Aylestone 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 Aylestone address specifically.
We price each Aylestone 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.
