Home for a hundred at least, maybe (6)
I believe the answer is:
castle
'home' is the definition.
(I know that castle is a type of country house)
'a hundred at least maybe' is the wordplay.
'a hundred' becomes 'C' (Roman numerals).
'at' says to put letters next to each other.
'maybe' indicates an anagram.
'least' with letters rearranged gives 'astle'.
'c'+'astle'='CASTLE'
'for' is the link.
(Other definitions for castle that I've seen before include "Chess piece and fortified building" , "secure place" , "splendid house" , "Fortified place on the chess board" , "Another word for chess rook" .)
