    Masonry void fill - structural

    Hi, I have to fill in the void of a removed chimney breast because half of a padstone supporting a UC 203x203x71 is situated there. How would you fill in the void (16cm thick) ? Blocks, bricks? A lintel may be required to build from, but unsure where to situate it.
