Wraparound extension in Redhill

Thinking about a wraparound extension in Redhill? An L-shaped extension that fills the side return and runs across the back. Our team handles the drawings, the planning route and the build, and your contract is with one company throughout.

We cover Redhill (RH1 and RH2) as part of our Surrey work. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Surrey where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Redhill?

Whether your wraparound extension in Redhill 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 Redhill like to extend?

Around Redhill 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.

Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
