Terraced house rear extension in Caerleon

For homes in Caerleon, a terraced house rear extension is often the simplest way to gain space without moving. Rear and side return extensions for terraces, with access through the house and two neighbours. We take it from survey to completion certificate.

We cover Caerleon (NP18) as part of our Newport and Monmouthshire work. In Caerleon we plan the delivery route through the house and the skip licence before anything else.

Terraced house rear extension prices in Caerleon

We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.

Do you need planning permission for a terraced house rear extension in Caerleon?

The planning route for a terraced house rear extension in Caerleon is set by Wales's householder rules and your council.

The Welsh Government's householder rules let many homes add a single-storey rear extension up to 4 metres deep and 4 metres high without a planning application. Deeper projects go through a householder application, because Wales has no prior approval route.

The Party Wall etc. Act 1996 also applies in Wales: two months' notice for work to a shared wall and one month for foundations dug close to a neighbour's building.

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 Caerleon like to extend?

Caerleon has Victorian terraces near the centre and semis further out. Welsh permitted development allows up to 4 metres at the rear for many houses.

How a terraced house rear extension in Caerleon comes together

  1. Look round and measure

    A free visit to see the back of the house, measure it, check the drains and boundaries and hear what you need.

  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

Terraced house rear extension questions in Caerleon

Do you handle building control in Caerleon?

Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.

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

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.

Will my terrace be in a conservation area?

Many Victorian terraces are. Your council's map shows it; we check at the survey.

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

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

How long does a rear extension take to build in Caerleon?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

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.
