Do you need planning permission for a wraparound extension in Shoreham-by-Sea?
Whether your wraparound extension in Shoreham-by-Sea 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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Shoreham-by-Sea like to extend?
Commuter semis and detached houses make up much of Shoreham-by-Sea, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Wraparound extension questions in Shoreham-by-Sea
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.
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.
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 get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
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.
Do you handle building control in Shoreham-by-Sea?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
