Frequently asked questions

Do you need planning permission to demolish a building?
Most demolition outside conservation areas is permitted development under Part 11 of the GPDO, but you must submit a prior-approval application covering method and restoration. Demolition of dwellinghouses always needs prior approval, even where permitted development applies.
What is a 'replacement dwelling' application?
Planning permission to demolish an existing dwelling and replace it with a new one. The principle is not automatic — councils assess the replacement against local policy on impact, scale, design and any heritage or rural-character considerations.
Can I get email alerts for demolition planning applications anywhere in Wales?
Yes. Click the "Set up alerts" button on this page and you'll get a daily (or weekly) email listing every new demolition application submitted anywhere in Wales. No need to pick a postcode or draw a map - pick the category once, choose your frequency, and we'll do the rest.
