Norma’s new house (5)
I believe the answer is:
manor
'house' is the definition.
(manor house is a kind of house)
'norma's new' is the wordplay.
'new' indicates an anagram.
'norma' with letters rearranged gives 'MANOR'.
(Other definitions for manor that I've seen before include "Lord's estate" , "Big house - police district" , "patch" , "house on estate" , "Landed estate" .)
