Terraced house rear extension in Folkestone
We plan and build rear extensions for terraced houses for homeowners in Folkestone. Rear and side return extensions for terraces, with access through the house and two neighbours. Start with a free site visit, then a written price once the design is agreed.
Folkestone is covered from our Kent round, including CT19 and CT20. On a Folkestone terrace both neighbours usually need party wall notices or agreement, so we talk to them early.

Do you need planning permission for a terraced house rear extension in Folkestone?
Planning for a terraced house rear extension in Folkestone follows the English householder rules.
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.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Folkestone like to extend?
Commuter semis and detached houses make up much of Folkestone, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Terraced house rear extension questions in Folkestone
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.
Can you match the brick or stone on my Folkestone house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
How do you keep the house clean?
Dust screens, floor protection and a single protected route through the house.
Do you handle building control in Folkestone?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
What postcode areas do you cover around Folkestone?
Including CT19 and CT20, and the surrounding Kent area.
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.
