Do I need planning permission in Yeovil?

In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).

In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.

Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.

If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.

Applications are decided by the local planning authority (your district, borough or unitary council).

Who a wraparound extension suits

  • Families who want kitchen, dining and living in one space
  • Semi-detached houses with a side passage
  • Terraced houses that want the largest ground floor possible

The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.

From first visit to completion

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

  1. Free site visit

    A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.

  2. Design and approvals

    Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.

  3. Fixed written price

    We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.

  4. Build and sign-off

    Work is carried out to the agreed programme, inspected by building control and signed off at the end.

Your questions about a wraparound extension in Yeovil

How long does a wraparound extension take to build in Yeovil?

On site, typically 14 to 20 weeks once approvals are in place. Before that, allow 8–16 weeks design and approvals.

Can I see a price before committing to anything?

Yes. The guide prices on this page are adjusted for Yeovil, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.

Do you cover all of Yeovil?

Yes. We cover Yeovil and the surrounding parts of Somerset. Site visits are free and there is no obligation.

Will I need to move a drain?

Often. Side returns frequently contain a manhole or a shared drain. Building near or over a public sewer needs the water company’s consent in England and Wales, which we arrange.

Do wraparound extensions need planning permission?

Usually, yes. In England the side element counts as a side extension and the rear element as a rear extension, and the combination normally falls outside permitted development. A householder application costs £548 in England from 1 April 2026.
