Rabbit to look radiant outside a house (8)
I believe the answer is:
bungalow
'house' is the definition.
(bungalow is a kind of house)
'rabbit to look radiant outside a' is the wordplay.
'rabbit' becomes 'bun'.
'to look radiant' becomes 'glow'.
'outside' indicates putting letters inside.
'glow' placed around 'a' is 'galow'.
'bun'+'galow'='BUNGALOW'
(Other definitions for bungalow that I've seen before include "One-storey building" , "cottage" , "One-storied house" , "One-storied dwelling" , "Single-storey home" .)
