Unspecified location for which homes were constructed (9)
I believe the answer is:
somewhere
'unspecified location' is the definition.
'homes were constructed' is the wordplay.
'constructed' is an anagram indicator.
'homes'+'were'='homeswere'
'homeswere' with letters rearranged gives 'SOMEWHERE'.
'for which' is the link.
(Other definitions for somewhere that I've seen before include "Indefinite or unknown location" , "In an unspecified place" , "uncertain regarding place" , "in unspecified location" , "'. . . . . . . . . Over the Rainbow' (song)" .)
