Society journalist’s roughly-built hut (5)
I believe the answer is:
shack
'roughly-built hut' is the definition.
(a shack is a basic dwelling)
'society journalist's' is the wordplay.
'society' becomes 's' (common abbreviation in names of organisations).
'journalist' becomes 'hack' (hack can informally mean a journalist).
's'+'hack'='SHACK'
(Other definitions for shack that I've seen before include "building made of wood?" , "basic accommodation" , "Hovel" , "Rough hut or cabin" , "Crude dwelling" .)
