In the Radio Times for today, the synopsis for Robin Hood has ". . .
Knighton Hall is razed to the ground . . ."

Nothing wrong with that as far as I can see.

The only thing I can find wrong with that is that they have spelt 'rased'
with a 'z'.

In the last decade or so it has become more common to use the 's' instead of
the 'z' in words such as rased (both are correct) to distinguish British
English from American English, the latter always use 'z'.
