Do you need planning permission for a kitchen-diner rear extension in Newton-le-Willows?
Here is how the rules in England apply to a kitchen-diner rear extension in Newton-le-Willows.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is 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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Newton-le-Willows like to extend?
Stone and brick terraces are common around Newton-le-Willows. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
