Local to Whitstable

Our survey diary covers Whitstable, including CT5. We also work in nearby Herne Bay (5 miles), Canterbury (6 miles), Faversham (7 miles), Sittingbourne (13 miles).

Southend-on-Sea, in Essex, is roughly 18 miles from Whitstable and also on our list. The South East has a broad mix of 1930s semis, post-war estates, newer developments and period cottages, and many houses have enough garden for a generous rear extension.

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.

Planning and approvals in Whitstable

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 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).

How the project works

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

    We draw the design, agree it with you and handle planning or permitted development checks and building regulations.

  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

    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 Whitstable

Do I need building regulations approval in Whitstable?

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

Will my neighbours in Whitstable 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.

Who do I contract with for a wraparound extension in Whitstable?

Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.

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.
