Two-storey extension drawings for Salford homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Salford City Council's design guidance, delivered in days and revised free until your decision.
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.
Adding at first floor changes the question the case officer asks. A single-storey extension is judged mostly on daylight and garden loss; a two-storey extension is judged on overlooking, bulk against the neighbouring roofline, and whether it reads as part of the house or bolted onto it. Salford is largely 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, and gabled, slate pitched roofs on the terraces and hipped roofs on the interwar semis set what a matching roof actually means here.
The permitted-development route exists but is narrow: 3 metres of rear projection, a 7-metre stand-off from the rear boundary, eaves and ridge no higher than the original, and side-facing upper windows obscure-glazed and non-opening below 1.7 metres above floor level. Most two-storey schemes fail one of those, usually the 7-metre boundary rule on a shorter garden, and go in as a full application instead. We establish which route applies before designing, because it changes the drawing set.
Large parts of Worsley, Boothstown and the north-west sit in Green Belt, where extensions face the openness test rather than ordinary householder policy. 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.
Some two-storey rear extensions are permitted development. You will need a full application to Salford City Council if any of these apply:
We set the projection and boundary distance on the site plan, prove the roof-pitch match on the elevations, and specify obscure glazing on the side windows — the three things Salford City Council checks first — then submit a validation-complete pack.
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. Two-storey schemes attract more neighbour comment than any other householder work, so the overlooking and daylight case has to be made on the drawings.

Across Eccles, Worsley and Swinton, the schemes that succeed set the first floor back from the ground floor, keep the ridge below the original, and treat the flank wall as blank or obscure-glazed. On victorian and edwardian brick terraces around ordsall, pendleton and weaste, matching the eaves line matters more than matching the brick: an extension that carries the existing eaves through reads as original even in a different material.
Flood risk along the River Irwell and Salford's brooks pulls sequential and mitigation questions into riverside schemes. We draw the 45-degree daylight test from the neighbour's nearest habitable window, show the window positions in section, and set out the steel and foundation implications early — a two-storey extension changes the load path, so the structural design and the planning design have to be developed together rather than in sequence.
We draw two-storey extensions across Salford. A few of the areas where they come up most often:
Two storey extension drawings for Eccles — Victorian suburb wrapping the affluent Ellesmere Park conservation area — dimensioned against the 3m and 7m limits and drawn to Salford City Council's guidance.
Two storey extension drawings for Worsley — the historic Worsley Village conservation area on the Bridgewater Canal — dimensioned against the 3m and 7m limits and drawn to Salford City Council's guidance.
Two storey extension drawings for Swinton — interwar and postwar semi-detached estates — dimensioned against the 3m and 7m limits and drawn to Salford City Council's guidance.
Two storey extension drawings for Monton — Victorian villas around the Monton Green conservation area — dimensioned against the 3m and 7m limits and drawn to Salford City Council's guidance.
Two storey extension drawings for Ordsall — Victorian terraces and redeveloped streets near the Quays — dimensioned against the 3m and 7m limits and drawn to Salford City Council's guidance.
Two storey extension drawings for Higher Broughton — Victorian villas and cobbled streets in The Cliff conservation area — dimensioned against the 3m and 7m limits and drawn to Salford City Council's guidance.
The first-floor limits are tighter than the ground-floor ones. This is how the common cases compare.
| Scheme | Permitted development? | Deciding limit | What Salford City Council checks |
|---|---|---|---|
| Two-storey rear, 3m projection, 7m+ to boundary | Often yes | 3m projection / 7m boundary | Roof match, side-window glazing |
| Two-storey rear, under 7m to boundary | No — full application | Rear-boundary distance | Overlooking, daylight, garden loss |
| Two-storey side extension | No — full application | Side elevation | Gap to boundary, street rhythm |
| Two-storey wraparound | No — full application | Combined footprint | Bulk, massing, neighbour amenity |
| Any two-storey on designated land | No — full application | Designation | Character and appearance |

A fixed process built around how Salford City Council validates and decides two-storey applications.
Send us your Salford postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Salford City Council decisions.
We measure the original rear wall, eaves and ridge heights, garden depth and every neighbouring window that faces the site — the inputs the daylight and overlooking case is built from.
Chartered designers develop the two-storey addition to your brief with the roof and eaves resolved, and we coordinate the load path so the structural scheme and the planning scheme are the same building.
We submit the application, manage validation and case-officer queries, and revise the drawings free until Salford City Council issues its decision.
Often, but not always. A two-storey rear extension can be permitted development if it projects no more than 3 metres, sits at least 7 metres from the rear boundary, does not exceed the existing eaves and ridge, and has obscure-glazed non-opening side windows below 1.7 metres. In Salford, the 7-metre rule is what most commonly forces a full application to Salford City Council.
No part of a permitted-development two-storey rear extension may come within 7 metres of the boundary opposite the rear wall of the house. It exists to protect the neighbour behind you from being overlooked at first floor. On shorter Salford gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Salford City Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to Salford City Council. They are assessed on the gap to the boundary, whether the street's rhythm of spaces between houses survives, and whether the extension is subordinate to the original. Setting the first floor back from the front building line and down from the ridge is what usually makes the difference.
Overlooking is the most common objection, and it is answerable on the drawings. We position habitable-room windows away from neighbouring gardens, obscure-glaze and fix shut anything on the flank below 1.7 metres, and show the sight lines in section. Where the geometry is tight, a rooflight or a high-level window gives the same daylight without the mutual overlooking that draws objections. This applies to your Salford address specifically. Salford City Council is the decision-maker.
Almost certainly. Excavating within 3 metres of a neighbouring structure and building on or up to the boundary both trigger the Party Wall etc. Act 1996, and a two-storey extension usually does both. It is entirely separate from Salford City Council's planning decision, so we flag the notice period early and detail the junction on the drawings.
Yes. Adding a floor changes the load path from roof to foundation, so beams, padstones and foundation depths all need designing and calculating for building control. Planning and building regulations are separate consents, and the structural set is what building control assesses — we prepare both so the approved scheme is the buildable one. This applies to your Salford address specifically. Salford City Council is the decision-maker.
