Orangery and conservatory drawings for Saltaire homes — checked against the Class A rear limits and the 30m² building-regulations exemption, drawn to Bradford Council's guidance 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.
The difference is not marketing. A conservatory is predominantly glazed — at least three quarters of the roof and half of the walls — which is what earns it the building-regulations exemption. An orangery has a solid masonry perimeter with a glazed lantern set into a flat roof, so it usually reads as a conventional extension for building control and has to meet Part L thermal standards, Part A structure and Part B fire like any other room.
Both are judged the same way for planning: as rear extensions, against the Class A depth, height and eaves limits, and against the Bradford Local Plan / Core Strategy. 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 the design question is usually whether the glazing reads as a lightweight addition to that stock or as a bolted-on conservatory kit. On period houses, an orangery with a properly proportioned lantern almost always sits better than a full-height glazed box.
In conservation areas such as Saltaire and Baildon Green, rear glazing is assessed on visibility from the street and on the effect on the rear elevation's character. 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.
Many conservatories are permitted development. You will need an application to Bradford Council where any of these apply:
We check the scheme against the Class A planning limits and against the building-regulations exemption at the same time, so you know before committing whether you are building an exempt conservatory or a fully regulated room.
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. Glazed rear additions are judged on depth, eaves height and how the glazing meets the existing elevation.

Across Salts Mill, Victoria Road and Albert Terrace, the schemes that succeed keep the eaves below the neighbour's ground-floor cill line, set the glazing back from the boundary, and use a solid parapet or brick perimeter to tie the addition into the house. On sir titus salt's 1850s italianate stone workers' cottages and through-terraces, a lantern set in a flat roof usually reads better than a pitched glazed roof, and it avoids the summer overheating that makes full conservatories unusable for months a year.
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. The decision worth making early is whether to keep the separating doors. Keeping them preserves the building-regulations exemption but leaves you with a room that is not part of the house; removing them creates one continuous space but brings the whole addition inside Part L, which changes the glazing specification and usually the heating design too. We set out both versions before you commit.
We draw glazed rear additions across Saltaire. A few of the areas where they come up most often:

The planning test is the same for both. The building-regulations test is not.
| Structure | Planning route | Building regulations | Practical effect |
|---|---|---|---|
| Conservatory under 30m², doors retained | Class A rear extension limits | Largely exempt | Cheaper build, unheated in winter |
| Conservatory, doors removed | Class A rear extension limits | Part L applies in full | Continuous space, higher spec glazing |
| Orangery with solid perimeter and lantern | Class A rear extension limits | Fully regulated | Usable year round, better on period houses |
| Any of the above beyond the depth limits | Full householder application | As above | 8-week determination |
| Any of the above on designated land | Full householder application | As above | Design and visibility assessed |
Planning limits from the GPDO 2015, Schedule 2, Part 1, Class A; exemption criteria from the Building Regulations 2010, Schedule 2, Class 7.
A fixed process covering both consents, because they pull in different directions.
Send us your Saltaire postcode and house type. We confirm the Class A limits that apply, check designation status, and score your odds against live Bradford Council decisions.
We measure the rear elevation, eaves and ground levels, and the neighbouring boundary — the numbers that decide both the projection limit and the 2-metre eaves rule.
Chartered designers develop the orangery or conservatory to your brief, and we set out clearly whether it stays inside the building-regulations exemption or becomes a fully regulated room.
We submit the certificate or application, manage validation and officer queries, and revise free until Bradford Council decides.
Often not. A conservatory is treated as a rear extension, so it can be permitted development within the Class A limits — 3 metres of projection on a terrace or semi, 4 metres on a detached house, with eaves under 3 metres where it sits within 2 metres of a boundary. In Saltaire you will need an application to Bradford Council beyond those limits, and on designated land such as Saltaire and Baildon Green.
A conservatory is largely exempt if it is under 30 square metres, at ground level, separated from the house by external-quality doors, and has at least 75% of its roof and 50% of its walls glazed. Glazing, electrics and any drainage work still have to comply. Remove the separating doors and the exemption falls away — the space becomes part of the house and Part L thermal standards apply. This applies to your Saltaire address specifically. Bradford Council is the decision-maker.
For planning, none — both are rear extensions assessed against the same Class A limits by Bradford Council. The difference is in building control: an orangery's solid perimeter and flat roof with a lantern usually means it fails the glazing test for exemption, so it is fully regulated. That is why an orangery costs more to build but is comfortable in January. This applies to your Saltaire address specifically.
Usually yes at the rear, though permitted-development rights are narrower on designated land and an Article 4 direction can remove them entirely. The assessment turns on whether the addition is visible from the street and how it meets the original rear elevation. A restrained orangery in matching brick with a lantern is consistently easier to get through than a proprietary glazed conservatory. This applies to your Saltaire address specifically. Bradford Council is the decision-maker.
A fully glazed roof will, unless it is specified for it. That is the practical reason most of our clients end up building an orangery instead: a solid insulated roof perimeter with a lantern gives daylight without the greenhouse effect, and keeps the space usable across the year. We raise it at design stage because it is much cheaper to solve on paper than after the build. This applies to your Saltaire address specifically. Bradford Council is the decision-maker.
If you excavate foundations within 3 metres of a neighbouring structure and deeper than its foundations, or build on the boundary itself, the Party Wall etc. Act 1996 applies and notice must be served. That is separate from Bradford Council's planning decision. We flag it at design stage so the notice period does not delay the start on site. This applies to your Saltaire address specifically.
We quote each Saltaire orangery or conservatory individually, because the structure and the roof form change the work considerably, and send a fixed, no-obligation quote within one working day.
