Store house by a road (5)
I believe the answer is:
hoard
'store' is the definition.
(hoard is a kind of store)
'house by a road' is the wordplay.
'house' becomes 'ho' (abbreviation for house).
'by' is a charade indicator (letters next to each other).
'road' becomes 'rd' (abbreviation).
'ho'+'a'+'rd'='HOARD'
(Other definitions for hoard that I've seen before include "Accumulate" , "Stockpile" , "Accumulation" , "Store of treasure" , "A lot of people" .)
