Not really sure where to post this on the forum or if it has been covered elsewhere but just wanted to alert people. From 1st Oct 2008 the rules for permitted development on house were amended. If you're planning on doing any work on your house which will affect the external appearance (particularly if you live in a national park, world heritage site or conservation area) then its worth checking with your local council or a planning advisor as you may now need permission.
Also, there is a 'virtual house' on the planning portal designed to give home owners an indication of what can and can't be done without permission but since the amendments it leaves a little to be desired as the amendments haven't been incorporated very clearly so for the time being i would use this as a guide and with caution!
