Kitchen-diner rear extensions in the Isle of Wight
An open-plan kitchen, dining and family room that opens straight onto the garden. Across the Isle of Wight we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Newport, Ryde and Cowes.
Island and remote addresses in the Isle of Wight are by arrangement: we confirm whether we can take the job, and agree any travel costs, before the first visit.
For Newport kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later. Around Isle of Wight the housing ranges from inter-war semis to 1960s and 1970s estates with good-sized gardens. Many of the newer estates had permitted development rights removed by condition, so we check the planning history before anything is drawn.

Do you need planning permission in the Isle of Wight?
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.

FAQ
Questions people ask
Should the sink face the garden?
If the plan allows, an island sink or hob facing the glass is a common choice. It needs a floor-level drain run, which is easy to lay in a new slab.
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.
Where does the cooker extraction go?
Through the new wall or roof, ducted to outside. Recirculating hoods are possible but less effective.
Do you cover all of the Isle of Wight?
We cover 6 towns and districts in the Isle of Wight, including Newport, Ryde and Cowes. Remote and island addresses are by arrangement.
