Do you need planning permission for a terraced house rear extension in Rottingdean?
Planning for a terraced house rear extension in Rottingdean 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.
Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.
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 Rottingdean like to extend?
Commuter semis and detached houses make up much of Rottingdean, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Terraced house rear extension questions in Rottingdean
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Can you build without side access?
Yes. Materials come through the house in protected runs or over the roof by crane on tight sites.
How long does a rear extension take to build in Rottingdean?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
What postcode areas do you cover around Rottingdean?
Including BN1 and BN2, and the surrounding East Sussex area.
Do you handle building control in Rottingdean?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
