Journalist provided with cold building (7)
I believe the answer is:
edifice
'building' is the definition.
(synonyms)
'journalist provided with cold' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'provided' becomes 'if' (eg 'provided it's sunny' means 'if it's sunny').
'with' means one lot of letters go next to another.
'cold' becomes 'ice' (I've seen this before).
'ed'+'if'+'ice'='EDIFICE'
(Other definitions for edifice that I've seen before include "impressive pile!" , "erection" , "Permanent building" , "Monument" , "Large structure" .)
