"A bush grew out of the gutter and hung down the front of the house."
Could anybody please explain where in the above sentence 'down' belongs? It could belong to 'hang' a bit like a phrasal verb, or it could belong to 'the front'?
That kind of construction is hard for a non-native speaker to get their head around. We understand the meaning of the sentence, of course, but it feels weird, nevertheless. A non-native speak would normally say something like that instead:
"A bush grew out of the gutter and hung (down) over/before/ the front of the house." "A bush grew out of the gutter and hung (down) in front of the house."

Down the front of the housea prepositional/adverbial phrase modifyinghung. The object of the phrase isthe front of the house. – Phoenix Jan 1 '12 at 12:57
