Back-of-house extension drawings for Salford homes — the glazed kitchen-diner across the rear, drawn to Salford City Council's depth and daylight 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 rear extension is the workhorse of Salford home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from 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, most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Salford City Council scrutinises. The council reads the proposal against the Salford Local Plan: Development Management Policies and Designations (adopted 2023) and the Places for Everyone joint Greater Manchester plan, 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. 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 rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — Ellesmere Park, The Cliff, Worsley Village, Monton Green, The Crescent and Roe Green among Salford's — the larger-home extension route is switched off and even a modest rear addition 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 survey.
Many single-storey rear extensions in Salford are permitted development and need no application. You will normally need to apply to Salford 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 Salford 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 Salford City Council's real householder decision record, taken 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. 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 Eccles, Worsley and Swinton, 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 victorian and edwardian brick terraces around ordsall, pendleton and weaste, 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.
Flood risk along the River Irwell and Salford's brooks pulls sequential and mitigation questions into riverside schemes. We keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Salford 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 Salford back-of-house projects come up most often:

How far you can extend at the back in Salford depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Salford 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 Ellesmere Park and The Cliff and Article 4 streets need a full application.
A fixed process built around how Salford City Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Salford 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 Salford 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 Salford 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 Salford 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 Salford. You will need to involve Salford 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 Ellesmere Park and The Cliff, 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 Salford 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 Salford's conservation areas.
It is the daylight test Salford 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.
A two-storey rear extension almost always needs a full householder application to Salford 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.
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 Salford City Council's planning decision. We flag it early and can prepare the drawings a party-wall surveyor needs alongside the planning set.
We price each Salford 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 Salford City Council approves, and we confirm at the outset whether your extension is permitted development, needs prior approval, or a full application.
