Where the Aire meets the Worth
Keighley started at the point where two rivers join, and that still shapes what you can build at the bottom of the town. The Environment Agency says roughly 460 homes and 290 businesses here are at risk of flooding from the Aire, the Worth and surface water, with Stockbridge carrying the higher risk.
Its flood warning areas name the streets. On the Aire side they take in Roydings Avenue, Florist Street, Aireworth Road, Aireworth Grove, Kinara Close and Garforth Road, plus parts of Bradford Road. On the Worth, the Worth Village warning covers homes off Dalton Lane, Worth Bridge Road and Aireworth Road.
If you live down there, look your address up on the flood map for planning before you draw anything. An extension in Flood Zone 2 or 3 needs a flood risk assessment sent in with the application. For a householder job the Agency's standing advice is fairly simple. Set the new floor at least 600mm above the estimated flood level, or where that can't be done, build in flood resistance and resilience up to that height.
Up the valley sides the worry is different. The British Geological Survey records coal seams once worked around Keighley and landslips on the steep sides of Airedale. Footings on a sloping plot deserve a proper look at the ground first.
Picking a type for a stone house in Keighley
Single storey rear. Most terraces and semis here can add 3 metres at the back without an application, or 4 on a detached house, and Bradford's own guideline sits at the same depths. There is no Article 4 direction anywhere in Keighley to take that right away.
Kitchen. Plenty of Keighley terraces have only a walled yard. The council will usually let you cover a yard too small to be much use, if the bins still fit.
Open plan. Knocking through the back wall of a stone terrace puts steel onto thick old masonry. Get the engineer to check the bearings before you sign a price.
Side return. Only works where a back wing leaves a slot of yard beside it. Find the drains early. Work over a public sewer, or within 3 metres of one, needs consent from the water company.
Two storey. Always an application. Bradford checks it against a 45 degree line from the neighbour's nearest habitable window, and in a conservation area permitted development won't cover any rear addition above one storey.
Wrap-around. A semi or detached job, and the side leg has to keep a 1 metre gap to the boundary where houses stand in a matching row. Inside a conservation area the side part needs permission.
Ground floor bedroom. A sensible answer on a hillside terrace where the stairs are steep. Keep it attached to the house, because a separate granny annexe can pull in the moorland rules below.
Home office. A small room built onto the back often beats a cabin here, since terrace yards rarely have space for one and the council resists anything that eats more than half a garden.
Planning. Two questions first. Is the house in one of the 18 conservation areas Bradford lists for the Keighley area, and is it near the rivers?
Cost. We print no Keighley prices. Matching stone, flood-proofing low floors and steel in old walls can all shift a quote, so get three and compare them item by item.
Devonshire Park and the trouble with adding bits on
The big Victorian houses up Skipton Road and Spring Gardens Lane were built for mill and machinery money, and plenty have since been extended more than once. Bradford's 2007 appraisal of the Devonshire Park and Cliffe Castle conservation area doesn't like what it saw. It points to one large building whose original is now overwhelmed by side and front additions, and warns that piecemeal, gradual extension of a historic house harms the street. It asks planners to weigh that more heavily.
So the second or third addition to a villa there gets tested against everything already stuck on it, not just against the house as you found it. The appraisal also discourages modern porches, and wants new building in gardens to keep the area open and green. Stone boundary walls matter too. Leave them, and don't paint or render the stone.
A plainly modern rear addition kept out of view from the road was judged neutral. Put the bulk at the back and match the walling.
Moors, Green Belt and the edge of town
Green Belt comes right up to Keighley. The Core Strategy even plans for some of the town's new homes on land released from it. If your house sits beyond the built-up edge, Bradford's Householder SPD measures any addition against the house as first built, or as it stood on 1 July 1948, and says more than 30% of that original volume is likely to be disproportionate.
The South Pennine Moors bring a separate rule. Under Core Strategy policy SC8, a residential granny annexe within 7 kilometres of the protected moorland is treated like a new home and has to provide mitigation for recreational pressure. An ordinary extension isn't on that list. Ask which zone you are in before designing anything self-contained.

Questions people in Keighley ask
I'm on a street off Aireworth Road. Can I still extend?
Yes, but check the flood map first. If the house is in Flood Zone 2 or 3, a planning application needs a flood risk assessment, and the Environment Agency's standing advice wants the new floor 600mm above the estimated flood level or flood resilient construction to that height.
Our villa in Devonshire Park already has a couple of additions. Will another be refused?
Not automatically, but the conservation area appraisal warns against piecemeal extension that swamps the original house. Expect the planners to judge the new part alongside the old ones, and keep it low, at the back and in matching stone.
Would a self-contained annexe for my mum need anything extra near the moors?
Possibly. Bradford's policy SC8 lists residential annexes among the developments that need mitigation within 7km of the South Pennine Moors. A bedroom and shower room built as part of the house is not on that list.
We live in Haworth. Can I add a side extension without permission?
No. Haworth is a conservation area, and there permitted development allows no side extensions and only single storey rear ones.
