Wraparound extension in Farnham

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

We cover Farnham (GU9 and GU10) 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 Farnham?

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

In England the side part of a side return or wraparound must meet the side-extension rules (one storey, under 4 metres high, no more than half the width of the original house), and those rights do not apply on designated land. Because a wraparound combines a side and a rear extension, many need householder planning permission.

Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.

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 Farnham like to extend?

Around Farnham 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 Farnham

What postcode areas do you cover around Farnham?

Including GU9 and GU10, and the surrounding Surrey area.

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.

How long does a wraparound take?

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

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

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

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.

Can you match the brick or stone on my Farnham house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
