House with its own tube station (5)
I believe the answer is:
manor
'house' is the definition.
(manor is a kind of house)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for manor that I've seen before include "Nobleman's land" , "Grand but strange Roman house" , "Police district (slang)" , "local copper's area" , "patch" .)
