Converted stables (4)
I believe the answer is:
mews
'converted stables' is the definition.
(houses converted from old stables)
This is the entire clue.
(Other definitions for mews that I've seen before include "Row of houses converted from stables" , "Street of homes converted from stables" , "Catcalls" , "Kittens' sounds" , "Fashionable town street" .)
