Distant motorway building (4)
I believe the answer is:
farm
'building' is the definition.
(farm building is a kind of building)
'distant motorway' is the wordplay.
'distant' becomes 'far' ('far' can be similar in meaning to 'distant').
'motorway' becomes 'm'.
'far'+'m'='FARM'
(Other definitions for farm that I've seen before include "Land, with buildings, used for agricultural purposes" , "Work the land" , "Grow crops or livestock" , "agricultural business" , "Ranch" .)
