Do you need planning permission for a two-storey rear extension in Scarborough?
Here is how the rules in England apply to a two-storey rear extension in Scarborough.
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 Scarborough like to extend?
Stone terraces and brick semis are typical of Scarborough. Matching sandstone or gritstone on a terrace is one of the biggest cost variables, and reclaimed stone is often the best match.

FAQ
Two-storey rear extension questions in Scarborough
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.
How much does a two-storey rear extension cost in Scarborough?
As a guide, £1,670–£2,510 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £50,000–£75,500 at that rate. Your written price follows the survey.
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.

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.

Yes. We visit, measure up and talk through the options with no cost and no obligation.
