Do you need planning permission for a bungalow rear extension in Maidenhead?
Whether your bungalow rear extension in Maidenhead needs a planning application depends on its size, your house and any local restrictions.
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 Maidenhead like to extend?
Commuter semis and detached houses make up much of Maidenhead, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Bungalow rear extension questions in Maidenhead

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

The same limits as a house: 3 or 4 metres in England, more with prior approval.

Including SL6, and the surrounding Berkshire area.
Do I need planning permission for a rear extension in Maidenhead?
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.
Can you match the brick or stone on my Maidenhead house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
