Journalist provided with cool building (7)
I believe the answer is:
edifice
'building' is the definition.
(I know that building can be written as edifice)
'journalist provided with cool' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'provided' becomes 'if' (eg 'provided it's sunny' means 'if it's sunny').
'with' says to put letters next to each other.
'cool' becomes 'ice' (icing is a kind of cooling).
'ed'+'if'+'ice'='EDIFICE'
(Other definitions for edifice that I've seen before include "Large structure" , "Fine building" , "'Large, imposing building (7)'" , "impressive pile!" , "erection" .)
