Lean-tos (5)
I believe the answer is:
sheds
'lean-tos' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sheds that I've seen before include "Single-storey outbuildings" , "Discards" , "Small huts as used in gardens" , "Casts off the outhouses?" , "Gets rid" .)
