Good spread for country house (6)
I believe the answer is:
grange
'country house' is the definition.
(I've seen this before)
'good spread' is the wordplay.
'good' becomes 'g' (abbreviation).
'spread' becomes 'range' (I've seen this in other clues).
'g'+'range'='GRANGE'
'for' is the link.
(Other definitions for grange that I've seen before include "Country house/farm" , "Country house with outbuildings" , "Country house with attached farm buildings" , "Farmhouse" , "US lodge" .)
