Two-storey extension drawings for Saltaire homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Bradford Council's design guidance, delivered in days and revised free until your decision.
Bradford Council granted 86% of the householder planning decisions it made in its latest published year — 1 point below the 87% England-wide householder average. As a UNESCO World Heritage Site inscribed in 2001, every scheme is judged against the Saltaire World Heritage Site setting and its Outstanding Universal Value, which is where a policy-literate drawing pack earns its keep. Its mixed housing stock sets the design brief street by street.
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. Saltaire carries at least one Article 4 direction, and conservation areas including Saltaire, Baildon Green and Wrose remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Saltaire is determined against an 8-week statutory target.
Salts Mill (Titus Salt's 1853 Italianate mill, now galleries and loft apartments), Victoria Road (the axial street of graded workers' cottages running to the institute), Albert Terrace (long ranks of stone through-terraces stepping up the hillside), Roberts Park (riverside villas and terraces facing the restored park across the Aire), George Street (tightly built two-storey cottages on the original 1850s grid) and Higher Coach Road (later stone housing on the Baildon side of the river and canal) — these are the Saltaire pockets our drawings cover most. Heritage designations here include Saltaire, Baildon Green and Wrose. Bradford Council weighs each proposal against the Bradford Local Plan / Core Strategy, where the entire village is listed, so like-for-like materials — millstone grit ashlar and Yorkshire stone slate — are effectively mandatory and uPVC and stone-painting are resisted. Converted apartments at Salts Mill and in the surrounding warehouses are flats with no householder permitted-development rights, on top of listed-building control.. On roofs the borough is Yorkshire stone-slate pitched roofs to the graded terrace ranks and hipped stone-slate roofs on the larger official houses, over Sir Titus Salt's 1850s Italianate stone workers' cottages and through-terraces, overlooker's and manager's larger stone houses and converted mill and warehouse apartments at Salts Mill.
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. Saltaire is largely Sir Titus Salt's 1850s Italianate stone workers' cottages and through-terraces, overlooker's and manager's larger stone houses and converted mill and warehouse apartments at Salts Mill, and Yorkshire stone-slate pitched roofs to the graded terrace ranks and hipped stone-slate roofs on the larger official houses 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.
As a UNESCO World Heritage Site inscribed in 2001, every scheme is judged against the Saltaire World Heritage Site setting and its Outstanding Universal Value. Saltaire has carried an Article 4 direction since 21 December 1976, and every residential property in the model village was additionally listed in 1984 — so external alterations, extensions and porches all need consent, with listed-building control now superseding the original direction.
Some two-storey rear extensions are permitted development. You will need a full application to Bradford 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 Bradford Council checks first — then submit a validation-complete pack.
Below is Bradford Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Bradford grants a clear majority of householder applications, but in Saltaire the World Heritage Site status and blanket listing make material authenticity, not principle, the decisive test. 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 Salts Mill, Victoria Road and Albert Terrace, 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 sir titus salt's 1850s italianate stone workers' cottages and through-terraces, 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.
The entire village is listed, so like-for-like materials — millstone grit ashlar and Yorkshire stone slate — are effectively mandatory and uPVC and stone-painting are resisted. 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 Saltaire. A few of the areas where they come up most often:
Two storey extension drawings for Salts Mill — Titus Salt's 1853 Italianate mill, now galleries and loft apartments — dimensioned against the 3m and 7m limits and drawn to Bradford Council's guidance.
Two storey extension drawings for Victoria Road — the axial street of graded workers' cottages running to the institute — dimensioned against the 3m and 7m limits and drawn to Bradford Council's guidance.
Two storey extension drawings for Albert Terrace — long ranks of stone through-terraces stepping up the hillside — dimensioned against the 3m and 7m limits and drawn to Bradford Council's guidance.
Two storey extension drawings for Roberts Park — riverside villas and terraces facing the restored park across the Aire — dimensioned against the 3m and 7m limits and drawn to Bradford Council's guidance.
Two storey extension drawings for George Street — tightly built two-storey cottages on the original 1850s grid — dimensioned against the 3m and 7m limits and drawn to Bradford Council's guidance.
Two storey extension drawings for Higher Coach Road — later stone housing on the Baildon side of the river and canal — dimensioned against the 3m and 7m limits and drawn to Bradford 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 Bradford 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 |
Limits from the GPDO 2015, Schedule 2, Part 1, Class A — two-storey rear extension conditions.
A fixed process built around how Bradford Council validates and decides two-storey applications.
Send us your Saltaire postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Bradford 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 Bradford 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 Saltaire, the 7-metre rule is what most commonly forces a full application to Bradford 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 Saltaire gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Bradford Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to Bradford 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. This applies to your Saltaire address specifically.
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 Saltaire address specifically. Bradford 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 Bradford Council's planning decision, so we flag the notice period early and detail the junction on the drawings. This applies to your Saltaire address specifically.
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 Saltaire address specifically. Bradford Council is the decision-maker.
We quote each Saltaire two-storey extension individually, because plot depth, roof form and structural complexity vary house to house, and send a fixed, no-obligation quote within one working day.
