Do you need planning permission for a two-storey rear extension in Buckley?
Planning for a two-storey rear extension in Buckley follows the Welsh householder rules.
Welsh rules allow a two-storey rear extension without an application only where the ground floor is no deeper than 4 metres, the upper floor no deeper than 3 metres and at least 10.5 metres remains to the rear boundary. Most homeowners still apply for householder planning permission.
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 Buckley like to extend?
Older terraces near the centre and post-war semis further out are typical of Buckley. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Two-storey rear extension questions in Buckley
Do I need planning permission for a rear extension in Buckley?
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 Buckley house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Will we need to move out?
Rarely. The first-floor opening is made late in the job and sealed with temporary screens.
