Choice given at building (7)
I believe the answer is:
vintage
'choice' is the definition.
(thesaurus)
'given at building' is the wordplay.
'building' indicates an anagram.
'given'+'at'='givenat'
'givenat' with letters rearranged gives 'VINTAGE'.
(Other definitions for vintage that I've seen before include "Wine of a good year" , "Excellent plonk" , "Wine harvest" , "Wine of a particular year" , "Describing cars built between 1919 and 1930" .)
