Do you need planning permission for a two-storey rear extension in Kirkdale?
Planning for a two-storey rear extension in Kirkdale follows the English householder rules.
A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.
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 Kirkdale like to extend?
Stone and brick terraces are common around Kirkdale. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier. In Kirkdale, a two-storey rear extension is worth comparing with the cost of moving once stamp duty, agents' and legal fees are counted.

FAQ
Two-storey rear extension questions in Kirkdale
Do I need planning permission for a rear extension in Kirkdale?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
Do you handle building control in Kirkdale?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Can I add an en-suite upstairs?
Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.
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.
How long does a rear extension take to build in Kirkdale?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
