Rear dormer drawings for Salford roofs — the box across the back slope that turns a low attic into a full-height room, drawn to Salford City Council's guidance and the volume limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Salford City Council granted 90% of the householder planning decisions it made in its latest published year — 3 points above the 87% England-wide householder average. Large parts of Worsley, Boothstown and the north-west sit in Green Belt, where extensions face the openness test rather than ordinary householder policy, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. Salford carries at least one Article 4 direction, and conservation areas including Ellesmere Park, The Cliff and Worsley Village remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Salford is determined against an 8-week statutory target.
Eccles (Victorian suburb wrapping the affluent Ellesmere Park conservation area), Worsley (the historic Worsley Village conservation area on the Bridgewater Canal), Swinton (interwar and postwar semi-detached estates), Monton (Victorian villas around the Monton Green conservation area), Ordsall (Victorian terraces and redeveloped streets near the Quays) and Higher Broughton (Victorian villas and cobbled streets in The Cliff conservation area) — these are the Salford pockets our drawings cover most. Heritage designations here include Ellesmere Park, The Cliff, Worsley Village, Monton Green, The Crescent and Roe Green. Salford City Council weighs each proposal against the Salford Local Plan: Development Management Policies and Designations (adopted 2023) and the Places for Everyone joint Greater Manchester plan, where flood risk along the River Irwell and Salford's brooks pulls sequential and mitigation questions into riverside schemes. Converted period houses and canal-side apartments are common around Broughton and the Quays, and flats carry no householder permitted-development rights.. On roofs the borough is gabled, slate pitched roofs on the terraces and hipped roofs on the interwar semis, over Victorian and Edwardian brick terraces around Ordsall, Pendleton and Weaste, grand Victorian and Edwardian villas in Ellesmere Park and The Cliff, interwar and postwar semi-detached houses across Swinton and Walkden and new-build apartments at Salford Quays and along the Irwell.
The box dormer is the workhorse loft, and most of Salford is built for it — the borough runs to Victorian and Edwardian brick terraces around Ordsall, Pendleton and Weaste, grand Victorian and Edwardian villas in Ellesmere Park and The Cliff, interwar and postwar semi-detached houses across Swinton and Walkden and new-build apartments at Salford Quays and along the Irwell under gabled, slate pitched roofs on the terraces and hipped roofs on the interwar semis, and a flat-roofed box across the rear slope is the cheapest cubic metre of full-height space those roofs give up. Salford City Council tests the dormer against the Salford Local Plan: Development Management Policies and Designations (adopted 2023) and the Places for Everyone joint Greater Manchester plan, 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. Large parts of Worsley, Boothstown and the north-west sit in Green Belt, where extensions face the openness test rather than ordinary householder policy, so the cheeks, the window line and the material are drawn to answer it rather than invite a query.
Where Salford's streets are protected — Ellesmere Park, The Cliff, Worsley Village, Monton Green, The Crescent and Roe Green among them — the Class B dormer right is switched off and even a modest rear box needs consent. Salford's sixteen conservation areas — Ellesmere Park and The Cliff among them — carry Article 4 directions that remove permitted-development rights on windows, roofs and boundary treatments, so external alterations on these Victorian streets need consent even where an ordinary suburban house would not. We confirm the designation before the box is sized.
Many rear dormers in Salford are permitted development, but the volume and position decide it. You will normally need a full application to Salford 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 Salford City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Salford grants a high share of householder applications, with Green Belt openness to the west and conservation-area character in the Victorian suburbs the main constraints. 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 Eccles, Worsley and Swinton, 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, slate pitched 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.
Flood risk along the River Irwell and Salford's brooks pulls sequential and mitigation questions into riverside schemes. 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 Salford 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 Salford dormers come up most often:

Whether a dormer in Salford 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 Salford 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 Ellesmere Park and The Cliff, Class B dormer rights are removed and every dormer needs a full application.
A fixed process built around how Salford City Council validates and decides dormer applications — most drawings are submission-ready within seven days of survey.
Send us your Salford 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 Salford 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 Salford City Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Salford 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 Salford you will need a full application to Salford City Council for a front or side dormer, a box that exceeds the volume, and any dormer in a conservation area such as Ellesmere Park and The Cliff, 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 Salford 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. Salford 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 Salford 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 Salford 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 Salford 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.
If your dormer is permitted development, a lawful development certificate from Salford 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.
We price each Salford 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 Salford City Council approves, and we confirm at the outset whether your box is permitted development or needs an application.
