Do you need planning permission for a terraced house rear extension in Welshpool?
The planning route for a terraced house rear extension in Welshpool 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. 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 Welshpool like to extend?
Welshpool 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
Terraced house rear extension questions in Welshpool
How long does a rear extension take to build in Welshpool?
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 you match the brick or stone on my Welshpool house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Do both neighbours need party wall notices?
Usually yes in England and Wales, because the extension often sits on or near both boundaries.

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 I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
