Kitchen-diner rear extension in Sheerness
An open-plan kitchen, dining and family room that opens straight onto the garden. We design, get the approvals for and build kitchen-diner rear extensions in Sheerness and the surrounding area, with one contract from the first survey to building control sign-off.
Sheerness and its postcode districts ME11 and ME12 are part of our Kent coverage. We usually keep the working kitchen where the old one was and put the dining table in the new space by the doors, which suits most Sheerness homes.

Do you need planning permission for a kitchen-diner rear extension in Sheerness?
The planning route for a kitchen-diner rear extension in Sheerness is set by England's householder rules and your council.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is within 2 metres of a boundary.
England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Sheerness like to extend?
Sheerness has a mix of Victorian terraces near the centre and larger Edwardian and inter-war houses further out. Clay soils across much of the South East mean deeper foundations near trees, which we plan for at the survey.

FAQ
Kitchen-diner rear extension questions in Sheerness
Do you handle building control in Sheerness?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
What postcode areas do you cover around Sheerness?
Including ME11 and ME12, and the surrounding Kent area.
Can I add a utility room?
Often. A narrow utility or boot room along one side keeps the washing machine out of the open-plan space.
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 I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
