Hi
Just put u-beams across garage to start building 1st floor extension.
Beams are 90mm wide each and will take 2 leaves of 100mm block work with 100mm cavity.
Is it best to centralise each beam under the block or can I put the blocks on so that they are flush at the front face and have 10mm over hang at the back (cavity side)?
Thanks
