Covering Norfolk

Towns we cover in Norfolk include Norwich, Great Yarmouth, King's Lynn, Thetford, Dereham, Wymondham, Cromer, North Walsham. The East of England mixes market-town terraces, inter-war semis and modern estates. Clay soils are common in parts of the region, which can affect foundation design.

Planning rules that apply in Norfolk

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).

Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.

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.

Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.

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

What is included

  • Party wall notice support (England and Wales)
  • Full internal finish or kitchen-ready shell
  • Foundations, drainage and any manhole relocation
  • Householder planning application
  • Survey, design and 3D layout options

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

    The price is fixed in writing once the design is settled, with a clear programme and payment stages.

  4. Build and sign-off

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

Common questions in Norfolk

Do you cover all of Norfolk?

Yes, across the whole of Norfolk. Site visits are free and there is no obligation.

Will my neighbours in Norfolk be involved?

If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.

Do I need building regulations approval in Norfolk?

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

How much does a wraparound extension cost?

Our guide range is about £2,120 to £3,920 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £60,500 to £77,000 in Norfolk before design and council fees.

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.
