Kitchen-diner rear extension in East Cowes

Kitchen-diner rear extension in East Cowes: an open-plan kitchen, dining and family room that opens straight onto the garden. We measure the house, show you what the rules allow, price it in writing and build it.

We cover East Cowes (PO31 and PO32) as part of our Isle of Wight work. For East Cowes kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later.

Do you need planning permission for a kitchen-diner rear extension in East Cowes?

Here is how the rules in England apply to a kitchen-diner rear extension in East Cowes.

Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.

If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.

What are homes in East Cowes like to extend?

Commuter semis and detached houses make up much of East Cowes, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

How a kitchen-diner rear extension in East Cowes comes together

  1. Look round and measure

    We see the back of the house, measure it, check the drains and boundaries and hear what you need.

  2. Drawings and budget

    Floor plans and elevations for the options, each with a guide price.

  3. Paperwork handled

    Planning, prior approval or permitted development, Building Regulations approval, structural design and party wall notices are all handled by us.

  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

Kitchen-diner rear extension questions in East Cowes

Who will build my extension?

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.

Can you match the brick or stone on my East Cowes house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Can I have underfloor heating?

Yes. Wet underfloor heating in the new screed is the usual choice, often with the old room's radiators kept or replaced.

Do you handle building control in East Cowes?

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

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.

Do I need planning permission for a rear extension in East Cowes?

Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
