Pontypool, South Wales Valleys

Two-storey rear extension in Pontypool

For homes in Pontypool, a two-storey rear extension is often the simplest way to gain space without moving. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We take it from survey to completion certificate.

We cover Pontypool (NP4 and NP44) as part of our South Wales Valleys work. In the South Wales Valleys we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

Do you need planning permission for a two-storey rear extension in Pontypool?

Whether your two-storey rear extension in Pontypool needs a planning application depends on its size, your house and any local restrictions.

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 Pontypool like to extend?

Stone terraces along the valley floors and post-war semis higher up are typical of Pontypool. Sloping sites are common, so floor levels and retaining walls are designed at the start.

How a two-storey rear extension in Pontypool comes together

  1. Free site visit

    We measure the house and garden, look at the back wall, drainage and boundaries, and talk through what you want from the space.

  2. Options and costs

    We draw layout options and price each one, so the budget shapes the design rather than surprising you later.

  3. Planning and regulations

    We take the design through the right planning route, then produce the construction drawings and engineer's calculations for building control.

  4. Written price, then build

    Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

FAQ

Two-storey rear extension questions in Pontypool

Do I need planning permission for a rear extension in Pontypool?

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.

Can you match the brick or stone on my Pontypool house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

What is the 45-degree rule?

Many councils check that a two-storey extension does not cross a 45-degree line drawn from the nearest habitable window of the neighbouring house. We test it at the first drawing.

What postcode areas do you cover around Pontypool?

Including NP4 and NP44, and the surrounding South Wales Valleys 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.

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.
