Information on Knocking Down A Supporting Wall
 

As I will be changing the room somewhat by knocking down a supporting wall. Do I need permissions from the local authorities to knock the supporting wall before I proceed? Incidentally, I live in the United Kingdom. I have had mixed messages from various people as to whether or not I do. I'd like a professional, preferably based in the UK, to answer my query so I can be absolutely certain.

I'm not a proffesional, but, I know a man who knows a bit about these things and he doesn't think you need permission.
But, and this is a big BUT, you do need to ensure that you have supported the joists, above the wall before you start demolishing any walls.
Failure to do so would probably result in a structural failure. :eek:
It is strongly recommended that you employ the services of a proffessional for this sort of job.
