There is a place where a conc wall protrudes above the level of the ceiling of the joists. It runs in line with the joists and the bottom of the blocks is just above the ceiling/plasterboard level, so it doesn't seem to serve any purpose.
There is also a place where a short steel beam bridges a corridor underneath. There is a row of conc blocks mortared on top of it which are already loose and seem to serve no purpose either.
Can I just remove them, so I can run the flooring right across the top or are they important for some reason?
(I noticed a place where a few have been removed for an expansion tank platform )
Thanks for any advice.
