What do rear extension planning drawings cost in Newport?
As a guide, £1,000–£2,500 including VAT for a single-storey rear extension, or £2,000–£3,500 for a two-storey scheme. Planning fees in Wales are set by the Welsh Government; we confirm the current householder fee when we prepare the application. Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission for a rear extension in Newport?
The planning route for a rear extension in Newport is set by Wales's householder rules and your council.
In Wales a rear extension of more than one storey can be permitted development if the ground floor projects no more than 4 metres and the upper floor no more than 3 metres, with at least 10.5 metres to the rear boundary. It is not permitted development in conservation areas, National Parks or National Landscapes, so many double-storey schemes need a householder application.
Welsh councils aim to decide householder applications within 8 weeks.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings 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 Newport like to extend?
Newport has Victorian terraces near the centre and semis further out. Welsh permitted development allows up to 4 metres at the rear for many houses.

FAQ
Rear extension planning drawings questions in Newport
Do I need planning permission for a rear extension in Newport?
Often not for a single-storey rear extension of up to 4 metres under Welsh permitted development. Wales has no prior approval route for deeper extensions.
Do you handle building control in Newport?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
Can planning conditions affect the build?
Yes, for example matching materials or obscure glazing. We plan for them.
What postcode areas do you cover around Newport?
Including NP10, NP18, NP19 and NP20, and the surrounding Newport and Monmouthshire 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.
Can you match the brick or stone on my Newport house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
