Do you need planning permission for a single-storey rear extension in Tottenham Hale?
Planning for a single-storey rear extension in Tottenham Hale follows the English householder rules.
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 Tottenham Hale like to extend?
Much of Tottenham Hale is Victorian and Edwardian terraced housing with narrow back additions, which suits side returns, wraparounds and 3 metre rear extensions. Many streets are in conservation areas, gardens are short, and almost everything comes through the house or along a rear alley. On Victorian and Edwardian terraces like those around Tottenham Hale, a single-storey rear extension is usually the simplest way to fix a small back kitchen without touching the bedrooms.

FAQ
Single-storey rear extension questions in Tottenham Hale
Do I need planning permission for a rear extension in Tottenham Hale?

Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
