Two-storey rear extension in Newport

Do you need planning permission for a two-storey rear extension in Newport?
The planning route for a two-storey 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.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a householder planning application.
What are homes in Newport like to extend?
Older terraces near the centre and post-war semis further out are typical of Newport. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Two-storey rear extension questions in Newport
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.
How much does a two-storey rear extension cost in Newport?
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 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 Newport?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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 get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
