Do you need planning permission for a two-storey rear extension in Hetton-le-Hole?
Planning for a two-storey rear extension in Hetton-le-Hole follows the English householder rules.
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
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
Two-storey rear extension questions in Hetton-le-Hole
How much does a two-storey rear extension cost in Hetton-le-Hole?
As a guide, £1,620–£2,430 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £48,500–£73,000 at that rate. Your written price follows the 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.
Can it be built on a terraced house?
Sometimes, but the upper floor is harder to get through planning on a terrace because of the effect on neighbours. A single-storey extension with a loft conversion is often an easier route.
Do I need planning permission for a rear extension in Hetton-le-Hole?
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.
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.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
