Run-down dwelling (5)
I believe the answer is:
hovel
'run-down dwelling' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hovel that I've seen before include "A wretched little dwelling" , "Grubby tumbledown dwelling" , "Run-down dwelling" , "Mean home" , "Dirty, neglected dwelling" .)
