Permitted Development Rights are a scheme, put together by the government, allowing you to extend / re-model your property without having to apply for full planning permission.
Recent changes made now allows permitted development for larger projects.
Homes excluded from the scheme
Homes in Scotland, Wales or Northern Ireland.
Homes built before 1948 will not be affected by permitted development changes, however they may be subject to much greater restrictions.
Similarly, homes in conservation areas are subject to greater restrictions.
Projects covered by permitted development
While the scheme has expanded it is always recommended to use the services of a professional to prepare drawings and if thought necessary discuss your permitted development with your local planning department.

It is also worth remembering, even of your project meets permitted development critiris it still has to comply to:
The best way forward is to prepare drawings and obtain a "Lawful Development Certificate"
