Building new part of city (7)
I believe the answer is:
antwerp
'city' is the definition.
(Antwerp is an example)
'building new part' is the wordplay.
'building' is an anagram indicator.
'new'+'part'='newpart'
'newpart' with letters rearranged gives 'ANTWERP'.
'of' is the link.
(Other definitions for antwerp that I've seen before include "Rent paw out in Belgium" , "9/11 [OLYMPIC VENUE]" , "Belgian city/port" , "New part of Dutch city" , "Major European port" .)
