Do you need planning permission for a two-storey rear extension in Knutsford?
Planning for a two-storey rear extension in Knutsford 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. 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 Knutsford like to extend?
Knutsford 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 Knutsford
What postcode areas do you cover around Knutsford?
Including WA16, and the surrounding Cheshire area.
Can you match the brick or stone on my Knutsford house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Will we need to move out?
Rarely. The first-floor opening is made late in the job and sealed with temporary screens.
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.
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.
