Wraparound extension in Ickenham

An L-shaped extension that fills the side return and runs across the back. We design, get the approvals for and build wraparound extensions in Ickenham and the surrounding area, with one contract from the first survey to building control sign-off.

Ickenham and its postcode districts HA4, UB8 and UB10 are part of our Greater London coverage. Wraparound projects around Ickenham often involve two neighbours, so we start the party wall conversations early.

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

Whether your wraparound extension in Ickenham 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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.

What are homes in Ickenham like to extend?

Ickenham is mostly 1930s semis, short terraces and post-war houses, so full-width single-storey and two-storey rear extensions are realistic on many plots. Some later estates had permitted development rights removed by condition, so we check the planning history first.

FAQ

Wraparound extension questions in Ickenham

Do I need planning permission for a rear extension in Ickenham?

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.

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.
