Back-of-house extension drawings for Keighley homes — the glazed kitchen-diner across the rear, drawn to Bradford Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
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. The setting of the listed Cliffe Castle and its registered park is weighed heavily on nearby schemes, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. In conservation areas such as Keighley Town Centre, Devonshire Park and Cliffe Castle and Low Utley those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Keighley is determined against an 8-week statutory target.
Keighley town centre (Victorian stone terraces and civic buildings in the conservation area), Devonshire Park (grander stone villas around Cliffe Castle and its park), Low Utley (an early stone hamlet protected as a conservation area), Steeton (the stone mill village in the Aire valley conservation area), Silsden (a market town of stone terraces and cottages up the valley) and Oakworth (millstone-grit terraces on the Worth valley slopes) — these are the Keighley pockets our drawings cover most. Heritage designations here include Keighley Town Centre, Devonshire Park and Cliffe Castle, Low Utley, Leeming, Steeton and Silsden. Bradford Council weighs each proposal against the Bradford Local Plan / Core Strategy, where dense back-to-back and through-terrace layouts leave little room for rear extensions without party-wall and daylight impacts. Converted flats are common in the Keighley terraces, and flats and maisonettes carry no householder permitted-development rights.. On roofs the borough is Yorkshire stone-slate pitched roofs on the terraces and back-to-backs and hipped stone-slate roofs on the villas, over dense Victorian millstone-grit terraces and back-to-backs, mill-town through-houses and gritstone semis and villas around the parks.
The rear extension is the workhorse of Keighley home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from dense Victorian millstone-grit terraces and back-to-backs, mill-town through-houses and gritstone semis and villas around the parks, most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Bradford Council scrutinises. The council reads the proposal against the Bradford Local Plan / Core Strategy, 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. The setting of the listed Cliffe Castle and its registered park is weighed heavily on nearby schemes, so the rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — Keighley Town Centre, Devonshire Park and Cliffe Castle, Low Utley, Leeming, Steeton and Silsden among Keighley's — the larger-home extension route is switched off and even a modest rear addition needs consent. Keighley carries no Article 4 direction, but the Keighley Town Centre, Devonshire Park and Cliffe Castle, and Low Utley conservation areas remove permitted-development rights across large parts of the Victorian stone townscape. We confirm the designation before the survey.
Many single-storey rear extensions in Keighley are permitted development and need no application. You will normally need to apply to Bradford 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 Bradford 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 Bradford Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Bradford grants most householder applications in Keighley, with dense terrace layouts and conservation-area stone controls the leading 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 Keighley town centre, Devonshire Park and Low Utley, 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 dense victorian millstone-grit terraces and back-to-backs, 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.
Dense back-to-back and through-terrace layouts leave little room for rear extensions without party-wall and daylight impacts. We keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Bradford 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 Keighley back-of-house projects come up most often:

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