Do you need planning permission for a bungalow rear extension in Rotherhithe?
Here is how the rules in England apply to a bungalow rear extension in Rotherhithe.
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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Rotherhithe like to extend?
Period terraces in Rotherhithe sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.

FAQ
Bungalow rear extension questions in Rotherhithe
Do I need planning permission for a rear extension in Rotherhithe?
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 I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
How deep can I extend?
The same limits as a house: 3 or 4 metres in England, more with prior approval.
Can you match the brick or stone on my Rotherhithe house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
