Do you need planning permission for a terraced house rear extension in Highgate?
Here is how the rules in England apply to a terraced house rear extension in Highgate.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.
Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.
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 Highgate like to extend?
Period terraces in Highgate sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.

Terraced house rear extension questions in Highgate
How much does a terraced house rear extension cost in Highgate?

Can you match the brick or stone on my Highgate house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Can a terrace have a two-storey rear extension?
It is possible but harder to get through planning because of the effect on both neighbours.
What postcode areas do you cover around Highgate?
Including N6, NW3 and NW5, and the surrounding Greater London area.
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.
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.
