More than one fell low-rise store fronts (5)
I believe the answer is:
moors
'more than one fell' is the definition.
('fell' can mean a moor)
'low-rise store fronts' is the wordplay.
'low' becomes 'moo' (both can mean to make a cow noise).
'fronts' indicates taking the first letters (I've seen 'front' mean this).
The first letters of 'rise store' is 'rs'.
'moo'+'rs'='MOORS'
(Other definitions for moors that I've seen before include "Secures" , "wild areas" , "wild places" , "Conquerors once" , "Ties up (vessel)" .)
