Outline new house title (10)
I believe the answer is:
silhouette
'outline' is the definition.
(silhouette is a kind of outline)
'new house title' is the wordplay.
'new' indicates anagramming the letters.
'house'+'title'='housetitle'
'housetitle' anagrammed gives 'SILHOUETTE'.
(Other definitions for silhouette that I've seen before include "Outline representation" , "image" , "Outline figure" , "Shadowy outline" , "Profile of characters" .)
