The issue i have is the metal beam in pics that i want to support is directly in line upwards where the load baring internal bricks would go. So to make this work i would have to have a larger footing with a very large cavity space. Not sure this would be good.
Just another question lads..In the below pics, the metal beam i want to brick up to would mean the top section around the outside where the beam is will be pretty hollow when i put the plaster board up..I suppose it should really brick up to the joists and remove the beam which would be pretty involved.

Firstly you move your wall over 50 or 100 mm so the load is centred between the new wall, easy fix. Certainly don't want a 200mm cavity.
Not sure what you mean re question 2.
Look I am not a builder or engineer, but as you are not too far away, I'd be happy to pop over and run through a few of your concerns with you. If you think my time is worth it to you, you could surprise me with a case of little creatures pale ale
Leave it with you.
