Facade of van (5)
I believe the answer is:
front
I believe this clue is a double definition.
'facade' is the first definition.
(I've seen this in another clue)
'van' is the second definition.
(van can mean the front part of something)
'of' is the link.
(Other definitions for front that I've seen before include "Facade" , "Meteorological boundary between different air masses" , "Seaside promenade" , "Vanguard; where armies fight" , "first" .)
