Stop in front of a humble building (8)
I believe the answer is:
bungalow
'building' is the definition.
(I've seen this before)
'stop in front of a humble' is the wordplay.
'stop' becomes 'bung' (bung is a kind of stop).
'in front of' is a charade indicator (letters next to each other) (some letters go in front of others).
'humble' becomes 'low' (synonyms).
'bung'+'a'+'low'='BUNGALOW'
(Other definitions for bungalow that I've seen before include "One-storeyed house" , "One-storeyed home" , "One-floor house" , "Type of house" , "It may house" .)
