Kitchen-diner rear extension in Mexborough
For homes in Mexborough, a kitchen-diner rear extension is often the simplest way to gain space without moving. An open-plan kitchen, dining and family room that opens straight onto the garden. We take it from survey to completion certificate.
Mexborough and its postcode districts S62 and S64 are part of our South Yorkshire coverage. A kitchen-diner is often the reason people in Mexborough extend: the back kitchen in back-to-back and through terraces is rarely big enough for a table.

Do you need planning permission for a kitchen-diner rear extension in Mexborough?
Here is how the rules in England apply to a kitchen-diner rear extension in Mexborough.
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 Mexborough like to extend?
Mexborough has through terraces and some back-to-backs as well as later semis; back-to-backs have little or no rear space, so we look at side or loft options there.

FAQ
Kitchen-diner rear extension questions in Mexborough
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 you match the brick or stone on my Mexborough house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Do you fit the kitchen?
Yes, whether you buy it yourself or we supply it. We take the measurements from the built shell, not the drawings.
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.
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.
Is the site visit in Mexborough free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
