Roman-style home (5)
I believe the answer is:
manor
'home' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'roman-style' is the wordplay.
'style' indicates an anagram (style can mean to shape or design).
'roman' with letters rearranged gives 'MANOR'.
Can you help me to learn more?
(Other definitions for manor that I've seen before include "home territory" , "Grand but strange Roman house" , "house on estate" , "Grand country house" , "police area" .)
