Wraparound extension in Fulham

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 Fulham and the surrounding area, with one contract from the first survey to building control sign-off.

Fulham and its postcode districts SW5, SW6 and SW10 are part of our Greater London coverage. In Fulham we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear.

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

Here is how the rules in England apply to a wraparound extension in Fulham.

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 Fulham like to extend?

Period terraces in Fulham sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.

FAQ

Wraparound extension questions in Fulham

How long does a rear extension take to build in Fulham?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

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.

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

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.

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.

Is the site visit in Fulham free?

Yes. We visit, measure up and talk through the options with no cost and no obligation.
