Area no longer having temporary accommodation (6)
I believe the answer is:
extent
'area' is the definition.
(thesaurus)
'no longer having temporary accommodation' is the wordplay.
'no longer' becomes 'ex'.
'having' is a charade indicator (letters next to each other).
'temporary accommodation' becomes 'tent' (I've seen this before).
'ex'+'tent'='EXTENT'
(Other definitions for extent that I've seen before include "A cake; last word of Macbeth" , "Area; size" , "The size or scale of something" , "Bulk - compass" , "Scope, area" .)
