Today's trend is to mass fill the footing with concrete

In my BCO patch that was the norma 30 years back: trying to do traditional
strip footings and lay bricks in a trench whose sides wanted to fall in
would have been no fun. And on the sort of clay we had, even 400mm wide
trench fill foundations are OK for two storeys.
