Got rid of cabin (4)
I believe the answer is:
shed
This clue is a double definition.
'got rid of' is the first definition.
(shed can mean to lose or cast off)
'cabin' is the second definition.
(both can mean a small building)
(Other definitions for shed that I've seen before include "Cast, wooden building" , "lost" , "Get rid of -- moult" , "Lose or take off in small building" , "Get rid of - garden building" .)
