House ultimately useful to aid hunting maybe (5)
I believe the answer is:
lodge
'house' is the definition.
(lodge is a kind of house)
'ultimately useful to aid hunting maybe' is the wordplay.
'ultimately' says to take the final letters.
The final letters of 'useful to aid hunting maybe' are 'LODGE'.
(Other definitions for lodge that I've seen before include "Deposit as to bank account" , "Stay temporarily, with bed and board" , "Settle" , "Become firmly fixed" , "Deposit put down" .)
