"The two joists had been shortened, then 'cross-joists'
attached between the ones outside at the wall and 18" back, then the
wood
hollowed out at an angle and the slab dropped in it."

This was a standard method of construction. The ends of the joists
were built usually into the walls. The joists were not built into the
chimney breast, containing the flues from the floor below, for obvious
reasons. A trimmer joist was fixed parallel to the chimney breast and
the 'shortened' joists and the concrete hearth were supported from
that. See Barry, 'Construction of Buildings' or similar textx.

" Removed the slab and replaced the joists."

Did you really? Oh dear.

Wouldnt that be contrary to the Building Regulations Act 1924, which
specified a minimum disance from hot flue gases to any woodwork?
