Heard van crashing from terrace (8)
I believe the answer is:
verandah
'terrace' is the definition.
'heard van crashing' is the wordplay.
'crashing' indicates an anagram.
'heard'+'van'='heardvan'
'heardvan' with letters rearranged gives 'VERANDAH'.
'from' is the link.
(Other definitions for verandah that I've seen before include "16 21 [INDIAN IMPORT]" , "Roofed area on the side of a house" , "gallery" , "Porch" , "Portico" .)
