Home provided over stay (8)
I believe the answer is:
fireside
'home' is the definition.
(I know that fireside is a type of home)
'provided over stay' is the wordplay.
'provided' becomes 'if' (eg 'provided it's sunny' means 'if it's sunny').
'over' shows that the letters should be reversed in order.
'stay' becomes 'reside' (I've seen this before).
'if' in reverse letter order is 'fi'.
'fi'+'reside'='FIRESIDE'
(Other definitions for fireside that I've seen before include "Domestic situation" , "in the home" , "Inglenook" , "One warmed by this" , "Warm part of room" .)
