Wraparound extension in Eastbourne
Wraparound extension in Eastbourne: an L-shaped extension that fills the side return and runs across the back. We measure the house, show you what the rules allow, price it in writing and build it.
Eastbourne and its postcode districts BN20, BN21 and BN23 are part of our East Sussex coverage. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in East Sussex where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Eastbourne?
Whether your wraparound extension in Eastbourne needs a planning application depends on its size, your house and any local restrictions.
Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
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 Eastbourne like to extend?
Around Eastbourne the housing ranges from inter-war semis to 1960s and 1970s estates with good-sized gardens. Many of the newer estates had permitted development rights removed by condition, so we check the planning history before anything is drawn.

FAQ
Wraparound extension questions in Eastbourne
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.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Will it take a lot of garden?
Less than a deep rear extension of the same area, because part of the space comes from the side passage.
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.
Do you handle building control in Eastbourne?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
