Do you need planning permission for a two-storey rear extension in Chester?

Here is how the rules in England apply to a two-storey rear extension in Chester.

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 Chester like to extend?

Chester has long runs of terraced houses with back yards and alleys, plus 1930s semis further out. Yard extensions on terraces are often single-storey and close to both boundaries.

FAQ

Two-storey rear extension questions in Chester

Can you match the brick or stone on my Chester house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

What postcode areas do you cover around Chester?

Including CH1, and the surrounding Cheshire area.

Can I add an en-suite upstairs?

Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.

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.

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.
