house... won't be a problem the problem comes at the internal wall end
where there would only be a 100mm. overlap this is obviously because the
internal wall is only a single brick ... what would you say is the best way of
making up the extra base ?? could we just simply leave a stub wall of half
brick or full brick of the wall that we're taking out at the internal wall end to
form a T Shape (a stubby T shape) and thus comfortably make up the
required 150mm. ... or is there a better looking way / method. or will the
councils building inspector accept the short 100mm. base in the first case.
maybe not... any thoughts ?

So am I right in thinking you will be making a `T` shaped pad stone?
The leg underneath the UB will be 315mm? (215mm (one brick) + 100mm (the wall it is perpendicular to))
Make it 300mm wide across the back and at least 150mm (2 courses) deep and you will have no probs. Use a good strong mix concrete like C30 to construct the padstone then the spread of the load will be more than adequate. This is based on the fact that it is a small steel section in the first place spanning 3m, so the loading is not astronomical at each end. If the floor above is only typical joist and floor board construction with a relatively low live load then cool. If you have a water bed or similar heavy load directly above and adjacent to this area then you mak have problems justifying the forces
