Do you need planning permission for a bungalow rear extension in Great Sankey?
Here is how the rules in England apply to a bungalow rear extension in Great Sankey.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.
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 Great Sankey like to extend?
Stone and brick terraces are common around Great Sankey. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

FAQ
Bungalow rear extension questions in Great Sankey
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.
How much does a bungalow rear extension cost in Great Sankey?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
