Cast provided with a humble dwelling (8)
I believe the answer is:
bungalow
'dwelling' is the definition.
(I've seen this before)
'cast provided with a humble' is the wordplay.
'cast' becomes 'bung' (both can mean to throw or fling).
'provided with' means one lot of letters go next to another.
'humble' becomes 'low' (similar in meaning).
'bung'+'a'+'low'='BUNGALOW'
(Other definitions for bungalow that I've seen before include "Single-storey house" , "One-floor house" , "One-storeyed house" , "Low building" , "Single storey house" .)
