Do you need planning permission for a kitchen-diner rear extension in Hetton-le-Hole?
Planning for a kitchen-diner rear extension in Hetton-le-Hole follows the English householder rules.
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. 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 Hetton-le-Hole like to extend?
Brick terraces, colliery houses and post-war semis make up much of Hetton-le-Hole. Former mining areas often need a coal mining risk check before foundations are designed.

FAQ
Kitchen-diner rear extension questions in Hetton-le-Hole
Is the site visit in Hetton-le-Hole free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can you match the brick or stone on my Hetton-le-Hole house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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 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.
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.
