Do you need planning permission for a two-storey rear extension in Barnoldswick?
Whether your two-storey rear extension in Barnoldswick needs a planning application depends on its size, your house and any local restrictions.
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Barnoldswick like to extend?
Stone and brick terraces are common around Barnoldswick. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

FAQ
Two-storey rear extension questions in Barnoldswick
What postcode areas do you cover around Barnoldswick?
Including BB18, and the surrounding Lancashire area.
How much does a two-storey rear extension cost in Barnoldswick?
As a guide, £1,690–£2,540 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £51,000–£76,000 at that rate. Your written price follows the survey.
Can it be built on a terraced house?
Sometimes, but the upper floor is harder to get through planning on a terrace because of the effect on neighbours. A single-storey extension with a loft conversion is often an easier route.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Do you handle building control in Barnoldswick?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
