I have a brick wall about to be rebuilt. It's about 5 - 6ft high and is a
9" construction, rather wobbly on it's lowest course and hence dangerous. It's about 8ft long and is a free standing construction without piers. The builder has been instructed by the landlord to reinstate the wall as it was without any piers.
I presume this doesn't follow good working practise. However are they any guidelines published of what is and isn't good working practise?
