Discards; buildings (5)
I believe the answer is:
sheds
This clue is a double definition.
'discards' is the first definition.
(I've seen this in another clue)
'buildings' is the second definition.
(shed is a kind of building)
(Other definitions for sheds that I've seen before include "Gets rid" , "Discards" , "Casts off the outhouses?" , "Small huts as used in gardens" , "Casts off the outbuildings" .)
