Provider rebuilt terrace (7)
I believe the answer is:
caterer
'provider' is the definition.
(caterer is a kind of provider)
'rebuilt terrace' is the wordplay.
'rebuilt' indicates an anagram.
'terrace' with letters rearranged gives 'CATERER'.
(Other definitions for caterer that I've seen before include "Someone needed for party" , "Provider of food and drinks" , "Provider of refreshments" , "Provider of food/drink" , "One supplying cheer" .)
