Bungalow rear extension in Edmonton
Bungalow rear extension in Edmonton: single-storey rear extensions that keep everything on one level. We measure the house, show you what the rules allow, price it in writing and build it.
We cover Edmonton (N9, N18 and N21) as part of our Greater London work. For Edmonton bungalows we design the roof first, because the low eaves decide the height of the new room.

Do you need planning permission for a bungalow rear extension in Edmonton?
Whether your bungalow rear extension in Edmonton needs a planning application depends on its size, your house and any local restrictions.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it 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 Edmonton like to extend?
Period terraces in Edmonton sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Is a bungalow extension cheaper?
The rates are similar per square metre; roof work can add a little.
Do you handle building control in Edmonton?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
