Frequently asked questions

What's the difference between outline and full planning permission?
Outline planning permission establishes the principle of development (is housing acceptable here?) while leaving specifics like layout and appearance to later applications. Full planning permission includes all details upfront. Outline is typically followed by 'reserved matters' applications that fill in the specifics.
What are 'reserved matters' in a planning application?
Details that an outline permission left to be approved later. There are five reserved matters: access, appearance, landscaping, layout and scale. They must usually be submitted within 3 years of the outline permission being granted.
How long does a planning decision for a new home take?
Statutory targets are 8 weeks for minor applications (1-9 dwellings) and 13 weeks for major applications (10+ dwellings), measured from the date the application is validated. Complex cases or appeals can take much longer.
Can I get email alerts for new homes applications in Gwynedd?
Yes. Click "Set up alerts" on this page and you'll get a daily or weekly email listing every new homes application published by Gwynedd. You can also narrow the alert to a postcode, street, or drawn area.

We check Gwynedd's planning portal daily. New homes applications appear here within a day of being published.
