Do you need planning permission for a two-storey rear extension in Broadstairs?
Planning for a two-storey rear extension in Broadstairs follows the English householder rules.
A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.
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 Broadstairs like to extend?
Commuter semis and detached houses make up much of Broadstairs, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Two-storey rear extension questions in Broadstairs
How much does a two-storey rear extension cost in Broadstairs?
As a guide, £2,020–£3,020 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £60,500–£90,500 at that rate. Your written price follows the survey.
Do I need planning permission for a rear extension in Broadstairs?
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 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.
How long does a rear extension take to build in Broadstairs?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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.
Is the site visit in Broadstairs free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
