Get rid of hut in garden (4)
I believe the answer is:
shed
This clue is a double definition.
'get rid' is the first definition.
(shed can mean to get rid of or discard)
'hut in garden' is the second definition.
(small building in a garden)
'of' acts as a link.
(Other definitions for shed that I've seen before include "made redundant" , "Remove clothes in small hut" , "Slough - outbuilding" , "place for bikes" , "something at the bottom of the garden?" .)
