Two kinds of slate, and a lot of chimneys
Keighley is built from the hills around it. Bradford Council's assessment of the town centre describes honey-coloured local stone, with stone slate on the older roofs and Welsh slate on most of what went up in the second half of the 19th century.
The roof covering matters more here than in most towns. The council's own roofing guidance calls Welsh slate cheaper, lighter and thinner than stone slate. So an old stone-slated roof is carrying a heavy load before anyone cuts into it, and your engineer's calculations should show it. Keep every stone slate that comes off for a dormer or a rooflight. The 2012 assessment warns that good stone slate is costly and hard to find, and the council wants it kept wherever it survives.
Then the chimneys. Every Keighley conservation appraisal we read, from the town centre out to Oakworth, names lowered or lost stacks as damage to the skyline. A loft job is often when someone suggests taking a stack down to free up space. Think hard before agreeing. On a terrace the chimneys are half of what the street looks like.
Mill owners' streets and hilltop folds
The town grew from 5,745 people in 1801 to 41,563 in 1901, and mill owners built much of the housing. Bradford Local Studies records the Brigg family of Calversyke Mill putting up better back-to-backs on Lynum Street, and James Lund of North Beck Mill building near Lund Park. Some of his houses from after 1878 still stand on Calton and Chelsea Streets. A lot of the earliest housing, around West Lane, was cleared after the Housing Act of 1930.
Stone terraces still set the tone. In the 2021 Census, 35.6% of households in the Keighley and Ilkley constituency lived in a terraced house, and 31.5% in a semi. Up the hill, Devonshire Park grew from the 1880s as the suburb for the town's wealthiest families, with stone villas and long terraces along Skipton Road. Guard House is different again. Keighley Corporation built its first 136 council houses there in 1928, each with a garden.
Round the edges sit hamlets that the town grew up to but never swallowed. Braithwaite, Hainworth and Low Utley kept their old farm groups and weavers' cottages. A barn or farmhouse in one of those folds is a one-off. Get a surveyor in before anyone talks about room sizes.
Eighteen conservation areas, and no Article 4
Bradford Council lists 18 conservation areas under its Keighley heading. In and close to the town they include Keighley Town Centre (built from the Church Street area of 1973 and Temple Street of 1978), Devonshire Park and Cliffe Castle, Low Utley, Braithwaite, Hainworth, Goose Eye and Laycock, and the Leeds Liverpool Canal. Up the Worth Valley there are Haworth, Oakworth, Stanbury and three at Oxenhope. Inside any of them, a dormer or hip to gable needs planning permission, on the back slope as well as the front. Rooflights are usually still allowed without an application.
Bradford's Householder SPD, adopted in 2012, is friendlier to dormers than many councils. In a conservation area it will normally allow a well designed pitched dormer on the front, up to 1.5 metres wide. Elsewhere a box dormer can be up to 3 metres. Read the Devonshire Park appraisal if you live there, though. It says dormers added to the Skipton Road terraces before 2007 harmed the roofline, and it wants new ones to suit the roof in size and materials.
There is no Article 4 direction in Keighley or the Worth Valley. The district's six are all in Bradford and Saltaire. Haworth's appraisal floated one to protect stone slate roofs if residents backed it, but none has been made.
Planning and building control both sit with Bradford Council, not Keighley Town Council. Building control is the council's own service, with inspections run by area teams split by ward. Keep the completion certificate. A buyer's solicitor will ask for it.
Fitting a conversion to a Keighley roof
Short notes on each type, with a link to the full guide.
Rear dormer. The usual choice on a stone through terrace with a yard behind. Outside a conservation area it is normally permitted development, up to 40 cubic metres on a terrace. Ask for the cheeks to be clad to match the roof, because the council dislikes plastic and shiplap.
Rooflights. The easy route in Haworth, Oakworth or the town centre, where any dormer means an application. Fit conservation units that sit low in the slates.
Hip to gable. Suits the semis that make up almost a third of local homes. The new gable has to be stone that matches the old in coursing and colour, so ask where your builder will get it.

L-shaped dormer. Possible on a terrace with a back wing under its own roof. Check that roof has the height before paying for drawings.
Planning. Find out first whether you are in one of the 18 conservation areas. That single fact decides whether a rear dormer needs an application.
Mansard. Rare on Keighley's stone terraces and a hard sell to planners. Expect a full application and an architect.
Extra bedroom. Why most people here convert. A small terrace gains a third bedroom without a move.
En-suite. Find the soil stack first. On a narrow terrace it decides where the shower room goes.
Home office. With electric trains to Leeds and Bradford, a few days a week at a desk up top suits plenty of people. Run a data cable while the floor is up.

Cost. No figures here. Reused stone slate and matching new stone can both move a Keighley price, and only a site visit shows which apply.

Questions people in Keighley ask
I live on Skipton Road in the Devonshire Park conservation area. Can I still have a dormer?
Yes, with planning permission. The SPD will normally accept a well designed pitched dormer up to 1.5 metres wide on the front of a house in a conservation area. The appraisal for Devonshire Park singles out the long terrace roofs as important, so a small dormer that suits the slates stands a far better chance than a wide box.
My roof is stone slate. Do I have to keep it?
In a conservation area the council expects stone slate to be kept wherever it survives. Outside one, permitted development still asks for materials similar to the house. Either way, reuse the slates that come off. Replacements are expensive and hard to find.
Is there an Article 4 direction anywhere in Keighley?
No. Bradford's six directions are in Saltaire, Manningham, Little Horton and Apsley Crescent. Keighley's 18 conservation areas already take away permitted development for dormers, though, so an Article 4 makes little difference to a loft.
Do I deal with Keighley Town Council or Bradford?
Bradford. The town council, restored in 2002, is a parish-level body. Planning applications and building control both go to City of Bradford Metropolitan District Council.
