Planning and approvals in Derbyshire

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.

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).

Local to Derbyshire

Towns we cover in Derbyshire include Derby, Chesterfield, Long Eaton, Ilkeston, Swadlincote, Staveley, Belper, Heanor. The East Midlands has plenty of inter-war and post-war semis and detached houses with room to extend, alongside Victorian terraces in the towns.

Who a wraparound extension suits

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

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.

Our process, step by step

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

    First, a site visit: we look at the house, garden, access and drains and listen to what you need.

  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

    We build it with one project manager, book the building control inspections and hand over the completion certificate.

Your questions about a wraparound extension in Derbyshire

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

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

Do I need building regulations approval in Derbyshire?

Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.

Can I see a price before committing to anything?

Yes. The guide prices on this page are adjusted for Derbyshire, 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 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.

Is a wraparound better than a side return alone?

It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
