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

Whether your wraparound extension in Feltham needs a planning application depends on its size, your house and any local restrictions.

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. 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 Feltham like to extend?

Feltham 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.

How a wraparound extension in Feltham comes together

  1. Look round and measure

    A free visit to see the back of the house, measure it, check the drains and boundaries and hear what you need.

  2. Options and costs

    We draw layout options and price each one, so the budget shapes the design rather than surprising you later.

  3. Planning and regulations

    We take the design through the right planning route, then produce the construction drawings and engineer's calculations for building control.

  4. Written price, then build

    Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

FAQ

Wraparound extension questions in Feltham

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.

How much does a wraparound extension cost in Feltham?

As a guide, £2,860–£4,680 per square metre including VAT for a standard specification. For example, L-shaped, about 22 m² of new floor: about £63,000–£103,000 at that rate. Your written price follows the survey.

How long does a wraparound take?

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

Do you handle building control in Feltham?

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

Can I live at home while the extension is built?

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.

What postcode areas do you cover around Feltham?

Including TW4, TW13 and TW14, and the surrounding Greater London area.
